Ifanadiana ERA5 Temperature

Air temperature measured at 2 meters above ground, 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 averages, expressed in Kelvin.

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_temp : average monthly temperature (Celsius)

Processing steps	temperature conversion in degrees Celsius / Data aggregation by fokontany/commune using spatial average (weighted mean). The average value was calculated using Google Earth Engine's reducer function, which computes a weighted mean based on the proportion of each pixel area that falls within the polygon boundary.
