Did you know? New Proba-V infographic

21 April 2020

ESA's vegetation-monitoring mission - Proba-V - will end operations in June 2020 after seven years. In honour of the occasion, and as the anniversary of the launch in May 2013 approaches, we took the occasion to summarise this minisatellite and its achievements in an infographic.

Mapping Chernobyl fires from space

16 April 2020

With an outbreak of wildfires recently threatening the closed Chernobyl nuclear power plant in the Ukraine, the Copernicus Emergency Mapping Service has been activated and the Copernicus Sentinel-2 satellite mission has imaged the fires and smoke, and mapped the resulting area of burned ground.

Air pollution remains low as Europeans stay at home

16 April 2020

Further analyses are showing the continued low levels of nitrogen dioxide concentrations across Europe – coinciding with lockdown measures implemented to stop the spread of the coronavirus. New data from the Copernicus Sentinel-5P satellite, from the European Union Copernicus programme, show some cities seeing levels fall by 45—50% compared to the same period last year.

Satellites and machine learning for water management

09 April 2020

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.

Unusual ozone hole opens over the Arctic

06 April 2020

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.

New life for Landsat historical data

01 April 2020

45 years of data, more than 1.8 million images, these are the numbers of an adventure started 48 years ago with the launch of the first Landsat satellite. Today, the entire Landsat Multispectral Scanner (MSS) ESA dataset has been processed with improved algorithms, so as to offer top quality data to the user community.

Coronavirus lockdown leading to drop in pollution across Europe

27 March 2020

New data, based on observations from the Copernicus Sentinel-5P satellite, are showing strong reductions in nitrogen dioxide concentrations over several major cities across Europe – including Paris, Madrid and Rome.

Land-cover maps of Europe from the Cloud

20 March 2020

Mapping land cover is not only essential for monitoring change, but it also underpins numerous practical applications. However, generating these maps entails handling huge amounts of satellite data and some technical expertise. Thanks to the Copernicus Sentinel-2 mission and new cloud-computing resources, fully automated land-cover maps in 10 m resolution are on the horizon.

Coronavirus: nitrogen dioxide emissions drop over Italy

13 March 2020

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.

Heritage Data still widely used today

06 March 2020

For about 30 years now, ESA satellites have been cruising some 800 km above our heads, collecting information about our planet—but why are older missions still so fundamental today?
