Monitoring of terrestrial evaporation from space

Monitoring from spaceClimate change alters the complex interplay between land and atmosphere, significantly impacting different processes in the global hydrological cycle.

Analysing these impacts requires long-term, observational, and consistent data sets of essential hydrological variables, such as soil moisture, precipitation, and terrestrial evaporation.

Unfortunately, the large-scale observation of terrestrial evaporation is hampered by the inability to sense this flux directly from satellites.

Consequently, the crucial return flow of water from land into the atmosphere remains one of the most elusive and uncertain components of the hydrosphere.

What we do

We develop and maintain a gobal evaporation model: GLEAM.

The model is fully dedicated to the estimation of terrestrial evaporation from satellite observable drivers of the flux.

Ever since its launch in 2011, the model has been widely used to investigate climate extremes, water management, climate model skill and trends in the hydrological cycle.
