Relative humidity represents the ratio between the quantity of water vapor present in the air and the maximum quantity the air can contain at a given temperature. Data are available from 2000 to 2023, with an initial spatial resolution of 11,132 meters. They are derived from the dew point temperature and the air temperature at 2 meters, according to the formula :
Relative Humidity = 100 * (exp((17.625 * TD) / (243.04 + TD)) / exp((17.625 * T) / (243.04 + T)))
where TD is the dew point temperature and T is the air temperature.
These data have been aggregated by Commune and Fokontany to calculate monthly averages, expressed as a percentage (%), where 100% indicates complete saturation of the air with water vapor.
