download_gridmet

Daily surface meteorological properties from GridMET. The workflow downloads weather and hydrological data for the input time range. Data is available for the contiguous US and southern British Columbia surfaces from 1979-present, with a daily temporal resolution and a ~4-km (1/24th degree) spatial resolution.
