Swarm probes weakening of Earth’s magnetic field

20.5.2020 13:10  

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

19.5.2020 11:00   Video: 00:04:00

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?

This video includes an interview with Josef Aschbacher, ESA’s Director of Earth Observation Programmes.

COVID-19: Aeolus and weather forecasts

21.4.2020 16:38   Fewer flights mean fewer atmospheric measurements

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.

9.4.2020 17:13   Water management key for sustainable agriculture

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

8.4.2020 11:00   ESA's ice mission

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.

Coronavirus: nitrogen dioxide emissions drop over Italy

13.3.2020 16:00   Video: 00:00:00

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.

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.

Coronavirus: nitrogen dioxide emissions drop over Italy

New data from the Copernicus Sentinel-5P satellite reveal the decline of air pollution, specifically nitrogen dioxide emissions, 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 emissions 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.

Bolivian highland heart

14.2.2020 10:00   Bolivian highland heart Image:

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

12.2.2020 14:10   Iceberg shattered Image:

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

11.2.2020 10:27   Video: 00:00:11

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 10 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, 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.”

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, 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.”

Earth from Space: Flevoland

7.2.2020 10:00   Video: 00:03:01

In this week's edition of the Earth from Space programme, 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.

Flevoland, the Netherlands

7.2.2020 10:00   Flevoland, the Netherlands Image:

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.
