Monthly twelve-digit hydrologic unit code aggregations of the CONUS404 bias adjusted application, 1979-2021

This data release contains accumulated precipitation data from the CONUS404 climate forcing variable subset for hydrologic models, downscaled to 1 km and bias-adjusted for precipitation and temperature (CONUS404-BA; Zhang and others, 2024) from January 1980 through September 2021 that is summarized to a monthly time step and a twelve-digit hydrologic unit code for the spatial extent of the conterminous United States. These data can be found in the “huc12_monthly_conus404ba_WY1980_WY2021.nc” file. Additionally, one supplementary file is also included in this data release. The additional file (“weights_grid_to_huc12_conus404ba.csv”) contains the spatial weights, or fraction, that is used to “weight” the source data in an area-weighting process.
