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.

ESA is addressing the challenge of cultivating and regenerating forests with Thematic Exploitation Platforms.
The aim is to unlock satellite data and make the information available to the non-expert along with the tools and resources they need – and critically make all this accessible from one place.
