Nearly four decades of soil moisture data now available
03 November 2017
A new, long-term and global dataset of soil moisture measurements from space has been released to help us better understand the water cycle and climate, monitor agriculture and manage our water resources.
The amount of water held in global soils makes up only about 0.001% of the total water found on Earth, but still plays a crucial role in regulating plant growth, our weather and climate.
This is because soil moisture is a key variable controlling the exchange of water and energy between the land and the atmosphere: dry soil emits little or no moisture to the atmosphere and heats up more strongly during a hot day, thus intensifying heatwaves. Wet soils, on the other hand, have a cooling effect on the atmosphere.

As part of a scientific collaboration with the Mexican Space Agency, ESA has combined images from the Copernicus Sentinel-2 mission to produce a detailed view of the vegetation growing across the entire country.
The high-resolution land-cover map combines images captured by Copernicus Sentinel-2 between 2016 and 2018.
