Snow mass estimates now more reliable

Estimating the amount of seasonal snow is important for understanding the water cycle and Earth’s climate system, but establishing a clear and coherent picture of change has proven difficult. New research from ESA’s Climate Change Initiative has helped to produce the first reliable estimate of snow mass change and has helped to identify different continental trends.

Swarm probes weakening of Earth’s magnetic field

In an area stretching from Africa to South America, Earth’s magnetic field is gradually weakening. This strange behaviour has geophysicists puzzled and is causing technical disturbances in satellites orbiting Earth. Scientists are using data from ESA’s Swarm constellation to improve our understanding of this area known as the ‘South Atlantic Anomaly.’

A sustainable future

With the Covid-19 pandemic halting our daily lives and forcing many countries and region into lockdown, the economic effects have been devastating. Closed borders have caused traffic jams and disrupted supply chains. In Europe, for example, the agriculture industry has suffered. Normally the industry relies on migrant labour to harvest crops, but as the lockdown continues, crops remain unpicked – putting farmers and the food supply under pressure. How can the food supply chain more sustainable?

Seen from space: COVID-19 and the environment

As the COVID-19 pandemic has disrupted lives across the globe, Earth-observing satellites take the pulse of our planet from space. While the global lockdown has had a massive impact on daily life and the economy, there have been environmental benefits that are visible from space. How can we preserve these positives when returning to ‘business as usual’?

Magnetic north and the elongating blob

For some years now, scientists have been puzzling over why the north magnetic pole has been making a dash towards Siberia. Thanks, in part, to ESA’s Swarm satellite mission, scientists are now more confident in the theory that tussling magnetic blobs deep below Earth’s surface are at the root of this phenomenon.

Aeolus goes public

Delivering new information about Earth’s winds, ESA’s Aeolus mission has already been hailed a success. Today, this remarkable satellite mission has yet again achieved new heights: its data are now being distributed publicly to forecasting services and scientific users in less than three hours of measurements being made from space.

Shedding light on the ocean’s living carbon pump

Phytoplankton play a crucial role in ocean biology and climate. Understanding the natural processes that influence phytoplankton primary production, and how they are changing as the planet warms, is vital. A new study, using data from the European Space Agency’s Climate Change Initiative, has produced a 20-year time-series of global primary production in the oceans – shedding new light on the ocean’s living carbon pump.

Building satellites amid COVID-19

During these unprecedented times of the COVID-19 lockdown, trying to work poses huge challenges for us all. For those that can, remote working is now pretty much the norm, but this is obviously not possible for everybody. One might assume that like many industries, the construction and testing of satellites has been put on hold, but engineers and scientists are finding ways of continuing to prepare Europe’s upcoming satellite missions such as the next Copernicus Sentinels.

Mapping methane emissions on a global scale

An important new tool to combat climate change is now available. Using data from the Copernicus Sentinel-5P satellite, this new technology makes it possible to track and attribute methane emissions around the world.

Earth Day: taking the pulse of our planet

Today marks the 50th anniversary of Earth Day. For Earth-observing satellites, every day is Earth Day. While news of COVID-19 dominates headlines and many of us practice social distancing, there still remains the need for action on climate change – and satellites are vital in providing the key facts on this global issue.  

COVID-19: Aeolus and weather forecasts

We are all too aware that COVID-19 is a serious threat to health, is putting huge pressure on healthcare systems and it could leave the global economy struggling for years to come. With lockdown measures in force across the globe, the pandemic is also affecting aspects of everyday life that may not be so obvious. The drop in commercial flights, for example, has led to fewer measurements for weather forecasts, but fortunately, ESA’s Aeolus satellite mission is helping to fill the gap.

Satellites and machine learning for water management

Freshwater is vital to life – but a growing global population, economic development and the effects of climate change are putting mounting pressure on this precious finite resource. Globally, agriculture accounts for 70% of all freshwater consumed, so efficient water management is essential. An ESA project that focuses on fusing data from two different Copernicus Sentinel missions is providing estimates of evapotranspiration, which is not only key for sustainable agriculture, but also important for water resource management and for a number of the United Nations’ Sustainable Development Goals.

CryoSat still cool at 10

Today marks 10 years since a Dnepr rocket blasted off from an underground silo in the remote desert steppe of Kazakhstan, launching one of ESA’s most remarkable Earth-observing satellites into orbit. Tucked safely within the rocket fairing, CryoSat had a tough job ahead: to measure variations in the height of Earth’s ice and reveal how climate change is affecting the polar regions. Carrying novel technology, this extraordinary mission has led to a wealth of scientific discoveries that go far beyond its primary objectives to measure polar ice. And, even at 10 years old, this incredible mission continues to surpass expectations.

Unusual ozone hole opens over the Arctic

Scientists using data from the Copernicus Sentinel-5P satellite have noticed a strong reduction of ozone concentrations over the Arctic. Unusual atmospheric conditions, including freezing temperatures in the stratosphere, have led ozone levels to plummet – causing a ‘mini-hole’ in the ozone layer.

COVID-19: nitrogen dioxide over China

Recent data have shown a decline of air pollution over northern Italy coinciding with its nationwide lockdown to prevent the spread of the coronavirus (COVID-19). This new map shows the variation of nitrogen dioxide concentrations over China from December to March – thanks to the Tropomi instrument on board the Copernicus Sentinel-5P satellite.

Coronavirus: nitrogen dioxide emissions drop over Italy

New data from the Copernicus Sentinel-5P satellite reveal the decline of air pollution, specifically nitrogen dioxide concentrations, over Italy. This reduction is particularly visible in northern Italy which coincides with its nationwide lockdown to prevent the spread of the coronavirus.

The animation shows the fluctuation of nitrogen dioxide concentrations across Europe from 1 January 2020 until 11 March 2020, using a 10-day moving average. These data are thanks to the Tropomi instrument on board the Copernicus Sentinel-5P satellite which maps a multitude of air pollutants around the globe.

Claus Zehner, ESA’s Copernicus Sentinel-5P mission manager, comments, “The decline in nitrogen dioxide concentrations over the Po Valley in northern Italy is particularly evident.

“Although there could be slight variations in the data due to cloud cover and changing weather, we are very confident that the reduction in concentrations that we can see, coincides with the lockdown in Italy causing less traffic and industrial activities.”

Josef Aschbacher, ESA’s Director of Earth Observation Programmes, says, “Copernicus Sentinel-5P Tropomi is the most accurate instrument today that measures air pollution from space. These measurements, globally available thanks to the free and open data policy, provide crucial information for citizens and decision makers."

The coronavirus disease (COVID-19) was recently declared a pandemic by the World Health Organisation, with more than 125 000 current cases of the disease reported globally. In Italy, the number of coronavirus cases drastically soared making it the country with the largest number of cases outside of China.

In an attempt to reduce the spread of the disease, Italy’s Prime Minister Giuseppe Conte announced a lockdown of the entire country – closing schools, restaurants, bars, museums and other venues across the country.

The Sentinel-5 Precursor – also known as Sentinel-5P – is the first Copernicus mission dedicated to monitoring our atmosphere. The satellite carries the Tropomi instrument to map a multitude of trace gases such as nitrogen dioxide, ozone, formaldehyde, sulphur dioxide, methane, carbon monoxide and aerosols – all of which affect the air we breathe and therefore our health, and our climate.

Given the growing importance and need for the continuous monitoring of air quality, the upcoming Copernicus Sentinel-4 and Sentinel-5 missions, as part of the EU’s Copernicus programme, will monitor key air quality trace gases and aerosols. These missions will provide information on air quality, stratospheric ozone and solar radiation, as well as climate monitoring.

Bolivian highland heart

For Valentine’s Day, we bring you this Copernicus Sentinel-2 image capturing a beautiful heart-shaped geographical formation in the dramatic landscape of the southern highlands of Bolivia.

The highlands are part of the Altiplano, meaning High Plateau, a region that stretches almost 1000 km from Peru to Bolivia. The landscape consists of a series of basins lying about 3500 m above sea level and is the most extensive area of high plateau on Earth, outside Tibet.

This particular area featured here is a transition between the desert in the west and the tropical forest in the east. The heart-shaped formation has been moulded by many layers of different geological formations over time. The many streams and rivers visible in this image have also contributed to the shaping of the landscape as we see it today. 

This false-colour composite image was processed by selecting spectral bands that can be used for classifying geological features – but here the image processing also highlights this lovely heart  for today’s image.

Sucre, the capital of the Chuquisaca Department, is visible at the top of the image in grey. Designated a UNESCO World Heritage Site, the city lies at an elevation of around 2800 metres above sea level. To the left of Sucre, the Maragua crater can be seen – a popular hiking destination. 

Satellites, such as Copernicus Sentinel-2, allow us to capture beautiful images such as these from space, but also  to monitor changing places on Earth. Flying 800 km above, satellites take the pulse of our planet by systematically imaging and measuring changes taking place, which is particularly important in regions that are otherwise difficult to access. This allows for informed decisions to be made to help protect our world for future generations and for all citizens that inhabit our beloved Earth.

We send all our love for Valentine’s Day from the high plateaus of Bolivia – and hope we continue our celebration of love for Earth every day of the year.

This image, which was captured on 26 January 2020, is also featured on the Earth from Space video programme.

Iceberg shattered

The Pine Island Glacier recently spawned an iceberg over 300 sq km that very quickly shattered into pieces. This almost cloud-free image, captured on 11 February by the Copernicus Sentinel-2 mission, shows the freshly broken bergs in detail.

A recent animation using 57 radar images captured by the Copernicus Sentinel-1 mission shows just how quickly the emerging cracks from the glacier grew – leading to this historic calving event.

Thanks to the combination of both optical and radar images from the Copernicus Sentinel satellite missions, growing cracks were spotted in the Pine Island Glacier last year, and since then, scientists have been keeping a close eye on how quick the cracks were growing.

The Pine Island Glacier, along with its neighbour Thwaites glacier, connect the centre of the West Antarctic Ice Sheet with the ocean, and together discharge significant quantities of ice into the ocean.

Pine Island Glacier spawns piglets

As anticipated, Pine Island Glacier, known as PIG for short, in Antarctica has just spawned a huge iceberg. At over 300 sq km, about the size of Malta, this huge berg very quickly broke into many ‘piglet’ pieces the largest of which is dubbed B-49. Thanks to images the Copernicus Sentinel satellite missions, two large rifts in the glacier were spotted last year and scientists have been keeping a close eye on how quickly these cracks were growing. This animation uses 57 radar images captured by the Copernicus Sentinel-1 mission between February 2019 and February 2020 (the last frame is from today, 11 February 2020) and shows just how quickly the emerging cracks grew and led to this calving event.

Pine Island Glacier, along with its neighbour Thwaites Glacier, connect the centre of the West Antarctic Ice Sheet with the ocean – together discharging significant quantities of ice into the ocean. These two glaciers have been losing ice over the last 25 years. Owing to their extremely remote location, satellites play a critical role in measuring and monitoring Antarctic glaciology – revealing the timing and pace of glacial retreat in Antarctica. Since the early 1990s, the Pine Island Glacier’s ice velocity has increased dramatically to values which exceed 10 m a day. Its floating ice front, which has an average thickness of approximately 500 metres, has experienced a series of calving events over the past 30 years, some of which have abruptly changed the shape and position of the ice front.
These changes have been mapped by ESA-built satellites since the 1990s, with calving events occurring in 1992, 1995, 2001, 2007, 2011, 2013, 2015, 2017, 2018, and now 2020.

Mark Drinkwater, senior scientist and cryosphere specialist remarked, “The Copernicus twin Sentinel-1 all-weather satellites have established a porthole through which the public can watch events like this unfold in remote regions around the world. What is unsettling is that the daily data stream reveals the dramatic pace at which climate is redefining the face of Antarctica.”

Pine Island Glacier spawns piglets

As anticipated, Pine Island Glacier, known as PIG for short, in Antarctica has just spawned a huge iceberg. At over 300 sq km, about the size of Malta, this huge berg very quickly broke into many ‘piglet’ pieces the largest of which is dubbed B-49. Thanks to images from the Copernicus Sentinel satellite missions, two large rifts in the glacier were spotted last year and scientists have been keeping a close eye on how quickly these cracks were growing. This animation uses 57 radar images captured by the Copernicus Sentinel-1 mission between February 2019 and February 2020 (the last frame is from today, 11 February 2020) and shows just how quickly the emerging cracks grew and led to this calving event.

Pine Island Glacier, along with its neighbour Thwaites Glacier, connect the centre of the West Antarctic Ice Sheet with the ocean – together discharging significant quantities of ice into the ocean. These two glaciers have been losing ice over the last 25 years. Owing to their extremely remote location, satellites play a critical role in measuring and monitoring Antarctic glaciology – revealing the timing and pace of glacial retreat in Antarctica. Since the early 1990s, the Pine Island Glacier’s ice velocity has increased dramatically to values which exceed 10 m a day. Its floating ice front, which has an average thickness of approximately 500 metres, has experienced a series of calving events over the past 30 years, some of which have abruptly changed the shape and position of the ice front.

Flevoland, the Netherlands

The Copernicus Sentinel-1 mission takes us over part of the Dutch province of Flevoland – the newest province in the Netherlands and one of the largest land reclamation projects in the world.

With almost a third of the country lying below sea level, the Netherlands is famously known as a ‘low country,’ and has a long history of land reclamation.

One reclamation project resulted in Flevoland. After a major flood it was decided to tame the Zuiderzee, a large, shallow inlet of the North Sea, to improve flood protection and also create additional land for agricultural use.

The project entailed the creation of land known as polders. The ‘Noordoostpolder,’ or the Northeast polder is the focus of this image. Over the years, the region has developed to become a home to a modern and innovative agricultural industry. The province produces predominantly apples, cereals, potatoes and flowers – with each colourful patch in the image representing a different crop.

This image combines three radar acquisitions from the Copernicus Sentinel-1 mission taken about two months apart to show change in crop and land conditions over time. The first image from 8 May 2018 is associated with red, the second from 7 July depicts changes in green, and the third from 5 September has been linked to blue.

Along the dikes of the Ijsselmeer, west of the Noordoostpolder, lies one of the largest wind farms in the Netherlands. The strong, almost star-shaped, reflections that can be seen near the shore are around 86 wind turbines. The wind farm is said to generate approximately 1.4 billion kWh of clean renewable energy per year – comparable to the power consumption of over 400 000 households.

Images acquired with radar are interpreted by studying the intensity of the backscatter radar signal, which is related to the roughness of the ground. Cities and towns are visible in white owing to the stronger reflection of the signal. Emmeloord can be seen in the centre of the Noordoostpolder, as well as several farms that appear as bright white dots along the roads.

This image is also featured on the Earth from Space video programme.

Space key to wetland conservation

Wetlands worldwide are vanishing at an alarming rate. New maps produced by ESA’s GlobWetland Africa project show how satellite observations can be used for the effective use and management of wetlands in Africa.

Earth from Space: Lake George

Ahead of World Wetlands Day, celebrated internationally each year on 2 February, this week's edition of the Earth from Space programme features a Copernicus Sentinel-2 image over Lake George in western Uganda. In 1988, Lake George was designated as Uganda’s first site under the Ramsar Convention - an international treaty for the conservation and sustainable use of wetlands.

Lake George, Uganda

World Wetlands Day is celebrated internationally each year on 2 February. It marks the anniversary of the signing of the Convention on Wetlands of International Importance, known as the Ramsar Convention, in Ramsar, Iran, on 2 February 1971.

World Wetlands Day raises global awareness about the vital role of wetlands for our planet, paying particular attention to wetland biodiversity.

This Copernicus Sentinel-2 image takes us over Lake George, in western Uganda. In 1988, Lake George was designated as Uganda’s first Ramsar site, given its importance as a centre for biological diversity.

This equatorial lake covers an area of around 250 sq km and has an average depth of around 2.4 metres. Lake George is fed by a complex system of rivers and streams originating from the Rwenzori mountains – supplying a system of permanent swamps surrounding the lake.

A dense fringe of wetland grass, visible in bright green, can be seen around the edges of the lake in the centre of the image.

The wetlands provide a natural living space for a number of mammals including elephants, hippopotamus and antelope. They also provide a habitat for over 150 species of birds including several rare species such as the saddle-billed stork.

Seen from above, the waters of Lake George appear green as a result of the thick concentration of blue-green algae. Metal pollution, mine seepage and agricultural runoff has caused serious pollution to the lake’s waters and are severely impacting the lake’s health.

Lake George drains through the Kazinga Channel in the image’s centre. The wide, 32km long channel connects Lake George with Lake Edward, which lies on the border between Uganda and the Democratic Republic of the Congo.

The Kazinga Channel flows through the Queen Elizabeth National Park. The almost 2000 sq km park is known for its wildlife including the African buffalo and the Nile crocodile.

The park is also famous for its volcanic features, including volcanic cones and deep craters which can be seen dotted around the image. Many contain crater lakes, including the Katwe crater lake, whose salt deposits have been mined for centuries.

Sentinel-2 is a two-satellite mission to supply the coverage and data delivery needed for Europe’s Copernicus programme. The mission’s frequent revisits over the same area and high spatial resolution allow changes in inland water bodies to be closely monitored.

CryoSat sheds new light on ice loss from Antarctica’s biggest glacier

Ice loss from Pine Island Glacier has contributed more to sea-level rise over the past four decades than any other glacier in Antarctica. However, the way this huge glacier is thinning is complex, leading to uncertainty about how it is likely to raise sea level in the future. Thanks to ESA’s CryoSat mission, scientists have now been able to shed new light on these complex patterns of ice loss.

Earth from Space: Deforestation in Bolivia

This week's edition of the Earth from Space programme features a Copernicus Sentinel-2 mage over an area in the Santa Cruz Department of Bolivia, where part of the tropical dry forest has been cleared for agricultural use.

Deforestation in Bolivia

This Copernicus Sentinel-2 image features an area in the Santa Cruz Department of Bolivia, where part of the tropical dry forest has been cleared for agricultural use.

Since the 1980s, the area has been rapidly deforested owing to a large agricultural development effort where people from the Andean high plains (the Altiplano region) have been relocated to the lowlands of Bolivia.

The relatively flat lowlands and abundant rainfall make this region suitable for farming. In fact, the local climate allows farmers to benefit from two growing seasons. The region has been transformed from dense forest into a patterned expanse of agricultural land. This deforestation method, common in this part of Bolivia, is characterised by the radial patterns that can be seen clearly in the image.

Each patterned field is approximately 20 sq km and each side is around 2.5 km long.

Small settlements can be seen in the centre of each individual field in the image, which typically contain a church, a school and a soccer field. These communities are joined by a road network depicted by the straight lines that bisect the radial fields and connect the adjacent areas.

Meandering streams and rivers can be seen flowing through the fields. The long, thin strips of land in the top right of the image are most likely cultivated soybean fields.

Rainforests worldwide are being destroyed at an alarming rate. This is of great concern as they play an important role in global climate, and are home to a wide variety of plants and animals.

Because of their unique perspective from space, Earth observation satellites are instrumental in providing comprehensive information on the full extent and rate of deforestation, which is particularly useful for monitoring remote areas.

This composite image was created by combing three separate ‘Normalised Difference Vegetation Index’ images from the Copernicus Sentinel-2 mission. The first image, from 8 April 2019, is visible in red; the second from 22 June 2019, can be seen in green; and the third from 5 September 2019 can be seen in blue. The Normalised Difference Vegetation Index is widely used in remote sensing as it gives scientists an accurate measure of healthy and status of plant growth.
