The water consumption monitoring service consists in providing estimations of actual evapotranspiration (ETa). Evapotranspiration is a significant process that drives the energy and water exchange between the atmosphere and the land surface and is defined as the sum of evaporation and crop transpiration. Actual evapotranspiration is a good estimate of water consumption in large heterogeneous areas where limited information is available. Quantitative information on ETa is important as it is related to plant growth, depletion of water resources, energy and gas fluxes. At large spatial scales ET estimations are crucial to understand land and atmosphere interactions in the context of global warming thus an ETa anomaly layer is provided extra.
