Lockdowns imposed to halt the spread of the coronavirus have been recently linked with cleaner air quality over Europe and China. New images, from the Copernicus Sentinel-5P satellite, from the European Union Copernicus programme, now show some cities across India seeing levels drop by around 40–50% owing to its nationwide quarantine.

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.

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.

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.

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.

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.
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.

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.

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.
