Zonal Statistics of Relative Humidity derived from ERA5-Land for Brazilian Municipalities, 1950-2025

This dataset provides daily mean and minimum zonal statistics of relative humidity (percent) for Brazilian municipalities from 1950 to 2025. The estimates are derived from Copernicus ERA5-Land daily aggregates of dew point temperature and mean 2-m air temperature, using the following formula: e_saturation = 6.11 * exp((2.5e6 / 461.52) * (1 / 273.15 - 1 / temp)) e_actual = 6.11 * exp((2.5e6 / 461.52) * (1 / 273.15 - 1 / dew_point)) rh = round(100 * (e_actual / e_saturation), 2) The full code is available here.
