Nitrogen dioxide pollution mapped

12 March 2019

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.

Proba-V 2018-2019 Antarctica data now available

07 March 2019

For the second consecutive austral summer season (see the 2018 news), Proba-V observed Antarctica and its ongoing changes: observations on the continent's land and sea ice surfaces were performed from 12 November 2018 until 18 February 2019.

EarthCARE mission to improve weather forecasts

06 March 2019

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.

Methane and ozone data products from Copernicus Sentinel-5P

04 March 2019

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.

Swarm helps pinpoint new magnetic north for smartphones

08 February 2019

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.

Flying under Aeolus

08 February 2019

Following the launch of Aeolus on 22 August 2018, scientists have been busy fine-tuning and calibrating this latest Earth Explorer satellite. Aeolus carries a revolutionary instrument, which comprises a powerful laser, a large telescope and a very sensitive receiver.
