Ifanadiana ERA5 Evapotranspiration

Potential evapotranspiration represents the maximum quantity of water that could evaporate from the soil and be transpired by vegetation under ideal conditions, without limitation of available water. Data are available from 2000 to 2023, with an initial spatial resolution of 11,132 meters. These data have been aggregated by Commune and Fokontany to calculate monthly totals, expressed in meters.

Columns :
- fid : numeric id of commune or fokontany
- date : date in format: YYYY-MM, corresponding to year and month
- new_commun : commune name after 2019
- old_commun : commune name before 2019
- comm_fkt : name of fokontany using standardized ‘new_commune’_’fokontany’ nomenclature
- mean_pev : spatial average of total monthly potential evapotranspiration (m)
