Whitney A. Seymour John A. Engott 20230526 maps and data Corvallis, OR, USA PRISM Climate Group at Oregon State University https://doi.org/10.5066/P9PLR5H1 Monthly 30-year "normal" dataset covering the conterminous U.S., including the Russian River watershed, averaged over the climatological period 1981-2010. Contains spatially gridded average monthly and average annual precipitation, maximum temperature, and minimum temperature at 800m grid cell resolution. Distribution of the point measurements to the spatial grid was accomplished using the PRISM model, developed and applied by Dr. Christopher Daly of the PRISM Climate Group at Oregon State University. This dataset was heavily peer reviewed, and is available free-of-charge on the PRISM website. The dataset was downloaded from the PRISM website in 2019 PRISM data was used as input to develop initial parameter values for the Russian River Integrated Hydrologic Model (RRIHM). The general purpose of the PRISM data is for display and/or analysis requiring spatially distributed monthly or annual precipitation, maximum temperature, or minimum temperature for the climatological period 1981-2010. This data release contains legacy data. User is advised to access source data for most up-to-date version of this dataset. 19810101 20101231 observed Complete None planned -125.0208 -66.4792 49.9375 24.0625 ISO 19115 Topic Category climatologyMeteorologyAtmosphere USGS Thesaurus hydrology modeling water resources USGS Metadata Identifier USGS:638a5e7ed34ed907bf79086a Common Geographic Areas California United States None Russian River None.

Henson 2018 publication https://www.sciencedirect.com/science/article/pii/S1364815217311908#sec9 All data were based on the same averaging period (1981-2010). Similar quality assurance procedures were used with all input data sets. Point estimates originated from some or all of the following sources: 1) National Weather Service (NWS) Cooperative (COOP) stations, 2) Natural Resources Conservation Service (NRCS) SNOTEL, 3) United States Forest Service (USFS) and Bureau of Land Management (BLM) RAWS Stations, 4) Bureau of Reclamation (AGRIMET) stations, 5) California Data Exchange Center (CDEC) stations, 6) Storage gauges, 7) NRCS Snowcourse stations, 8) Other State and local station networks, 9) Estimated station data, 10) Canadian stations, 11) Upper air stations, 12) NWS/Federal Aviation Administration (FAA) Automated surface observation stations (ASOS), 13) Community Collaborative Rain, Hail, and Snow Network stations (CoCoRaHS), 14) Soil Climate Analysis Network (SCAN), 15) Oklahoma Mesonet, 16) Weather Bureau Army Navy (WBAN), and 17) Colorado Agricultural Meteorological Network (CoAgMet). All COOP station data were subjected to quality control checks by the National Climatic Data Center (NCDC). All COOP, SNOTEL and other data were subjected to further quality control checks by PRISM Climate Group at Oregon State University. Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Accuracy of this data set is based on the original specification of the Defense Mapping Agency (DMA) 1 degree digital elevation models (DEM). The stated accuracy of the original DEMs is 130 m circular error with 90% probability.

Spatially gridded average monthly and annual surfaces for precipitation, maximum temperature, and minimum temperature averaged over the climatological period 1981-2010 were downloaded from the PRISM website. A total of 39 surfaces were downloaded - 13 for each climate variable - precipitation, maximum temperature, and minimum temperature.
