SMOS on speed

14 October 2016

While ESA's water mission was built to advance our understanding of Earth, it continues to show how well it's suited to delivering information for numerous applications that improve everyday life. Taking this a step further, soil moisture data products are now available within three hours of measurement, which is essential for many applications.

Sentinel-3 and the ocean carbon conundrum

25 February 2016

Each year, about a quarter of the carbon dioxide we release into the atmosphere ends up in the ocean, but how it happens is still not fully understood. The Sentinel-3A satellite is poised to play an important role in shedding new light on this exchange.

Five years of soil moisture and beyond

03 November 2014

ESA's SMOS satellite has clocked up more than one billion kilometres orbiting Earth to improve our understanding of our planet's water cycle. Marking its fifth birthday, all the data collected over land and ocean have been drawn together to show how moisture in the soil and salinity in the ocean change over the year.
