This data release contains inputs for and outputs from hydrologic simulations for the Alaska (AK) domain using the Precipitation Runoff Modeling System (PRMS) version 5.2.1.1 and the USGS National Hydrologic Model infrastructure (NHM, Regan and others, 2018). Historical simulations using the Daymet Version 4 gridded estimates of daily weather parameters (Thornton and others, 2020) were produced for the period 1980 – 2021. These data document the PRMS output data files for the precalibration and byHRU release runs for the AK domain. Each .zip folder contains 15 NHM-PRMS output variables, in NetCDF format, for each simulation's release run and the Water-Budget File with the model-domain summary table of the AK domain (Markstrom and others, [...]

The main landing page provides additional information and a data dictionary (output_variables_data_dictionary.csv) which describes the selected output variables.

The purpose of this data release is to provide an archive of the Alaska NHM PRMS files needed to run the AK NHM and replicate.
This work contributes to an understanding of the hydrologic cycle of the State of Alaska and the part of the Canadian Yukon Territory draining into Alaska. The domain has been modeled using the Precipitation Runoff Modeling System (PRMS; pubs.usgs.gov/tm/6b7/pdf/tm6-b7.pdf; https://www.usgs.gov/software/precipitation-runoff-modeling-system-prms) as part of the Integrated Water Availability Assessments (IWAA), Water Resources Mission Area (WMA), National Hydrologic Modeling applications (AK NHM; https://www.usgs.gov/mission-areas/water-resources/science/integrated-water-availability-assessments). 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.
