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.

Copernicus Sentinel-3 provides added capability in land monitoring

28 February 2019

With two sensors now in orbit, the Copernicus Sentinel-3 satellites could monitor some parts of the world almost daily. This capability could be crucial in monitoring rapidly developing events such as biotic/abiotic stress on crops and provide accurate and timely information from farmers to policy-makers, to develop appropriate mitigation strategies.

On its 5th Anniversary, GPM Still Right as Rain

27 February 2019

Five years ago, on 27 Feb., 2014, the Global Precipitation Measurement (GPM) Core Observatory, a joint satellite project by NASA and the Japan Aerospace Exploration Agency (JAXA), lifted off aboard a Japanese H-IIA rocket. Since then, the cutting-edge instruments on GPM have provided advanced measurements about the rain and snow particles within clouds, Earth's precipitation patterns, extreme weather and myriad ways precipitation around the world affects society. Among the uses of GPM data are helping to forecast disease outbreaks in developing countries, producing global crop reports and identifying endangered Amazon river basins.

Copernicus Sentinel-1 reveals shared plumbing led to Agung awakening

22 February 2019

When Mount Agung in Indonesia erupted in 2017, the search was on to find out why it had stirred. Thanks to information on ground deformation from the Copernicus Sentinel-1 mission, scientists now have more insight into the volcano's hidden secrets that caused it to reawaken.

EarthCARE mission to improve weather forecasts

12 February 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.

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.

More of Africa scarred by fires than thought

04 February 2019

Wildfires can cause devastation and are also to blame for more than a quarter of greenhouse gases being released into the atmosphere. Satellites play a key role in mapping landscape scarred by fire – but the Copernicus Sentinel-2 mission has revealed that there are more fires than previously thought.
