Sando, R., Olsen, T.D., Kaiser, K.E., Haluska, T.L., and Hockman-Wert, D.P., 2018, Climatic CPGs -- Probability of Streamflow Permanence (PROSPER) Continuous Parameter Grids (CPGs): U.S. Geological Survey data release,


These datasets are continuous parameter grids (CPG) of total annual precipitation data for the years 2000 through 2016 in the Pacific Northwest. One 30-year normal (average) annual precipitation grid from the period 1981-2010 is also included. Source precipitation data was produced by the PRISM Climate Group at Oregon State University.

These Continuous Parameter Grid (CPG) rasters were generated as inputs to the PROSPER model, predicting the probability of streamflow permanence throughout the Pacific Northwest. Each model predictor variable (parameter grid) was converted from its original spatial form into a CPG, which combines the discrete values with a flow accumulation raster, thereby converting the predictor values into a spatially moving average format.
