download_terraclimate

Monthly climate and hydroclimate properties from TerraClimate. The workflow downloads weather and hydrological data for the input time range. Data is available for global terrestrial surfaces from 1958-present, with a monthly temporal resolution and a ~4-km (1/24th degree) spatial resolution.
