geobricks.compute_relative_humidity(*, dewpoint_input_file, temperature_input_file, pressure_input_file, method='Penman-Monteith')[source]#

Compute relative humidity from 2m dewpoint, 2m temperature and surface pressure.

Each input may be a file path, an xarray.Dataset (with the historical short names d2m/t2m/sp or with any single data variable) or an xarray.DataArray (units must be K for temperatures and Pa for pressure, matching ERA5 conventions). Returns a Dataset with a single relative_humidity variable in %. The pressure argument is currently unused by both formulas but is required by the signature for future use (e.g. wet-bulb extensions).
