Soil Moisture Essential Climate Variable

The important role of soil moisture for the environment and climate system is well known. Soil moisture influences hydrological and agricultural processes, runoff generation, drought development and many other processes. It also impacts on the climate system through atmospheric feedbacks. Soil moisture is a source of water for evapotranspiration over the continents, and is involved in both the water and the energy cycles. Soil moisture was recognised as an Essential Climate Variable (ECV) in 2010.

Soil moisture and the Water-Energy-Food Nexus


In recent years, the Water-Energy-Food Nexus has become a ‘hot topic’ at international conferences, workshops and debates. Soil moisture has a great potential benefit for the W-E-F nexus and a global soil moisture monitoring system that captures spatial and temporal trends in moisture conditions is of importance.

ENSO dominates multi-decadal dynamics in terrestrial evaporation

Modified from Miralles et al. 2013

A recent study funded by the European Space Agency has just been published in Nature Climate Change (Miralles et al., 2013). The work uses satellite data of terrestrial evaporation (ET), together with independent observations of soil moisture and NDVI, to uncover a strong link between ET and the dynamics of the El Niño-La Niña cycle.
