New potential for tracking severe storms

14.5.2019 13:45  

Even just within the last couple of months, Cyclones Fani, Idai and Kenneth have brought devastation to millions. With the frequency and severity of extreme weather like this expected to increase against the backdrop of climate change, it is more important than ever to forecast and track events accurately. And, an ESA satellite is helping with the task in hand.

Jakobshavn Isbrae Glacier bucks the trend

14.5.2019 10:55  

Our planet works in mysterious ways. We are all used to hearing about the world’s ice being the first casualty of climate change and, indeed, it is declining fast. However, recent findings show that one glacier is not conforming to the norm – it’s actually been flowing more slowly and getting thicker.

Joining forces on Earth science to benefit society

13.5.2019 16:20  

With human activity leaving its indelible mark on the landscape and affecting the climate, our natural world is changing faster than at any other time in history. Science is fundamental to understanding environmental change so that these huge challenges can be tackled. To ensure a more efficient approach on Earth-system science and to bring direct benefits to society, ESA and the European Commission are working to join forces.

Spotlight on the pulse of our planet

13.5.2019 14:48  

Satellites deliver crucial information to help solve what is our biggest global problem: climate change. As well as taking the pulse of our planet, satellite data are used in a myriad of daily applications, and are also used increasingly in business. It’s no surprise then that over 4 000 people have flocked to Milan to hear the latest scientific findings on Earth’s natural processes and global change, and to learn about the wealth of new opportunities that Earth observation has to offer.

Getting ready to chart sea level

12.4.2019 15:38  

Records show that, on average, global sea level rose by 3.2 mm a year between 1993 and 2018, but hidden within this average is the fact that the rate of rise has been accelerating over the last few years. Taking measurements of the height of the sea surface is essential to monitoring this worrying trend – and the Copernicus Sentinel-6 mission is on the way to being ready to do just this.

Glaciers lose nine trillion tonnes of ice in half a century

8.4.2019 17:10  

When we think of climate change, one of the first things to come to mind is melting polar ice. However, ice loss isn’t just restricted to the polar regions. According to research published today, glaciers around the world have lost well over 9000 gigatonnes (nine trillion tonnes) of ice since 1961, raising sea level by 27 mm.

Satellites key to addressing water scarcity

22.3.2019 11:30  

Today is World Water Day, but with millions of people in Mozambique, Malawi and Zimbabwe struggling to cope in the aftermath of Cyclone Idai, the notion of water shortages may not be at the forefront of our minds right now. Even so, floods, like we see here, lead to real problems accessing clean water. Whether the problem is inundation or water scarcity, satellites can help monitor this precious resource.

As millions of people in Mozambique, Malawi and Zimbabwe struggle to cope with the aftermath of what could be the southern hemisphere’s worst storm, Copernicus Sentinel-1 is one of the satellite missions being used to map flooded areas to help relief efforts.

Taking gravity from strength to strength

20.3.2019 9:09  

Ten years ago, ESA launched one of its most innovative satellites. GOCE spent four years measuring a fundamental force of nature: gravity. This extraordinary mission not only yielded new insights into our gravity field, but led to some amazing discoveries about our planet, from deep below the surface to high up in the atmosphere and beyond. And, this remarkable mission continues to realise new science today.

12.3.2019 16:50  

New maps that use information from the Copernicus Sentinel-5P satellite reveal nitrogen dioxide emission being released into the atmosphere in cities and towns across the globe.

Working towards AI and Earth observation

11.3.2019 11:46  

Satellites observing and measuring our planet deliver a huge amount of data that not only helps understand how our world is changing, but also benefits society by feeding into a myriad of everyday applications. Taking this to the next level, ESA is exploring how even more could be gained from these valuable data by using artificial intelligence (AI).

New observations for the new economy

8.3.2019 15:41  

We all listen to weather forecasts and know they rely on satellite data. What may not be so obvious is that many other aspects of our lives depend on robust satellite data, from growing crops to tackling the major issue of climate change. The socio-economic benefits of Earth observation are huge, and increasing. In Europe, ESA, Eumetsat and the EU work closely together, in long-term partnerships, to make sure these benefits are delivered.

Methane and ozone data products from Copernicus Sentinel-5P

4.3.2019 17:50  

The Copernicus Sentinel-5P mission has been used to produce global maps of two atmospheric gases responsible for making our world warmer: methane, which is a particularly potent greenhouse gas, and ozone, which is a greenhouse gas and a pollutant in the lower part of the atmosphere. The maps give insight into where these gases are coming from.

EarthCARE mission to improve weather forecasts

12.2.2019 16:01  

Earth observation satellite data are crucial for generating accurate weather predictions. They provide a global picture of the current state of the atmosphere, which is used as the starting point for creating a forecast. But our knowledge of that current state is limited, partly because satellites have so far not been able to collect much information about clouds, which play a key role in the weather. The ESA/JAXA future mission EarthCARE will provide this information to improve our predictions about the future weather and climate.

Swarm helps pinpoint new magnetic north for smartphones

8.2.2019 16:45  

Since it was first measured in 1831, we have known that the magnetic north is constantly on the move. However, its tendency to slowly roam has stepped up a pace recently – so much so that the World Magnetic Model has had to be updated urgently with the pole’s new location, vital for navigation on smartphones, for example. ESA’s magnetic field Swarm mission has been key for this update.

Slow flow for glaciers thinning in Asia

10.12.2018 17:15  

Providing water for drinking, irrigation and power, glaciers in the world’s highest mountains are a lifeline for more than a billion people. As climate change takes a grip and glaciers lose mass, one might think that, lubricated by more meltwater, they flow more quickly. However, satellite images from over the last 30 years show that it isn’t as simple as that.

Another El Niño on the horizon?

7.12.2018 11:00  

The jury is still out as to whether climate change will lead to stronger El Niño events, but while representatives from around 200 countries at the COP24 conference are working to breathe life into the 2105 Paris Agreement, there is a 75–80% chance that a fully-fledged event could be with us in the next couple of months.
