Data & Resources
Description
Precipitation at fokontany or commune level corresponds to all the water falling to the ground in the form of rain, snow, hail or any other form of atmospheric precipitation. These data, expressed in meters, exclude fog and dew. They cover the period from 2000 to 2026, with a spatial resolution of 11,132 meters and a monthly temporal resolution. An additional aggregation was also performed at the level of the 500-meter buffer zones around the IHOPE survey villages, providing village-level monthly estimates for each site.

🔹 Processing Steps
Conversion of data from meters to mm and 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.
