Description:
Abstract: 
Monthly 30-year "normal" dataset covering the Susquehanna River Basin, averaged over the climatological period 1991-2020. Contains spatially gridded average total precipitation 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 is available free-of-charge on the PRISM website.
Purpose: 
Dataset modified to fit the needs of the Susquehanna River Basin Commission. Display and/or analysis requiring spatially distributed total precipitation for the climatological period 1991-2020.
Supplemental_Information: 
There are many methods of interpolating climate from monitoring stations to grid points. Some provide estimates of acceptable accuracy in flat terrain, but few have been able to adequately explain the extreme, complex variations in climate that occur in mountainous regions. Significant progress in this area has been achieved through the development of PRISM (Parameter-elevation Regressions on Independent Slopes Model). PRISM is an analytical model that uses point data and an underlying grid such as a digital elevation model (DEM) or a 30 yr climatological average to generate gridded estimates of monthly or annual precipitation and temperature (as well as other climatic parameters). PRISM is well suited to regions with mountainous terrain, because it incorporates a conceptual framework that addresses the spatial scale and pattern of orographic processes. Grids were modeled on a monthly basis. Annual grids were produced by averaging (temperature, vapor pressure, vapor pressure deficit, and solar radiation) or summing (precipitation) the monthly grids.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: 
All data were based on the same averaging period (1991-2020). Similar quality assurance procedures were used with all input data sets.
Logical_Consistency_Report: 
Point estimates originated from many federal, state, and local weather networks. A list of networks is available from https://www.prism.oregonstate.edu/documents/PRISM_datasets.pdf. All station data were subjected to quality control checks by the PRISM Climate Group at Oregon State University.
Completeness_Report: 
This dataset is considered complete. Please view the logic section of this document for further information.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: 
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 are 130 m circular error with 90% probability.
