Mean-monthly global gridded calibration targets and parameter values derived from monthly-mean Global Circulation Model (GCM) simulations, January 1980 - November 2022

This work contributes to an understanding of the global hydrologic cycle. Global Circulation Model (GCM) data from National Aeronautics and Space Administration (NASA) were processed into 10 mean-monthly global datasets stored in NetCDF formatrepresenting 12 mean-monthly layers ( .nc file extension; https://www.unidata.ucar.edu/software/netcdf/ ). These NetCDF files are used as calibration targets and (or) parameter values for Precipitation Runoff Modeling System (PRMS; pubs.usgs.gov/tm/6b7/pdf/tm6-b7.pdf; https://doi.org/10.5066/P9LVUWDC) National Hydrologic Modeling (NHM) applications ( https://www.usgs.gov/mission-areas/water-resources/science/integrated-water-availability-assessments..Integrated Water Availability Assessments | U.S. Geological Survey (usgs.gov). PRMS is a deterministic, distributed-parameter, physical-process-based modeling system developed to evaluate the response of streamflow and general basin hydrology to various combinations of climate and land use.

DATA TYPE DESIGNATION

SM       Soil moisture
SR        Solar radiation
SRO     Surface runoff
SSR     Subsurface runoff.
SWE     Snow-water equivalent
SWI      Soil-water infiltration
