Aratos Earth Observation Data Platform supports a new map layer for Agricultural Irrigation and Water Resource Management.

In the renewed system of Aratos Earth Observation Data Platform the up-to-date Evapotranspiration (ET) layer is added. Water vapor flux or Evapotranspiration (ET) is a complicated process, consisting of the evaporation of water from the soil and water intercepted by the canopy, as well as of the transpiration from plant leaves. Physiological, soil and climatic variables are involved in these processes.

The role of ET in the decision-making procedure concerning water requirements for the crops, climatic characterization and for water management in general is of great importance. The estimation of ET from vegetated areas is a basic tool to compute water balances and to estimate water needs and availability.


We continue to innovate with space technologies since 2005.
