I would like to know if there are any (generalized) coefficients which relate crop evapotranspiration with total Precipitation, taken into account land use distribution of CORINE classification. As far as I know, apart from the specific crop coefficients, which are out of my scope, there is a reference from Katzensteiner (1999) which assesses evapotranspiration according to vegetation in % of the annual precipitation for only 3 classes (3.1, 3.2, 3.3.2) of CORINE. Is anyone familiar with any updates or alternatives?
Yes there is some studies which try to estimate evapotranspiration using precipitation and land cover (not necessarily based on CORINE classification). eg. is the study done by Ward E. Sanford and David L. Selnick
ESTIMATION OF EVAPOTRANSPIRATION ACROSS THE CONTERMINOUS UNITED
STATES USING A REGRESSION WITH CLIMATE AND LAND-COVER DATA
in JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION
where the authors relate precipitation and land cover to estimate evapotranspiration in the following way (see attached file)
