Description:
Abstract:
This data set contains spatially gridded precipitation of average monthly and annual precipitation for the climatological period 1961-90. Distribution of the point measurements to a spatial grid was accomplished using the PRISM model, developed by Chris Daly of SCAS/OSU.
Purpose:
Display and/or analyses requiring spatially distributed monthly or annual precipitation for the climatological period 1961-90.
Supplemental_Information:
There are many methods of interpolating precipitation 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 precipitation 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 a digital elevation model (DEM) to generate gridded estimates of monthly and annual precipitation (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 precipitation. Precipitation was modeled monthly. An annual grid was produced by summing the monthly grids. A Gaussian filter was applied to increase the resolution of the grids from the base resolution 2.5 arc-minutes (~4 km) to 1.25 arc-minutes (~2 km). This filter is a modification of the Barnes filter (Barnes, 1964), originally adapted by Dr. Stephen Esbensen of Oregon State University, and later modified for use here by Wayne P. Gibson, also of Oregon State University.

Data_Quality_Information:
Logical_Consistency_Report:
All data were based on the same averaging period (1961-1990). Similar quality assurance procedures were used with all input data sets.
Completeness_Report:
Point estimates of precipitation originated from the Taiwan Central Weather Bureau. All station data were subjected to quality control checks by the Spatial Climate Analysis Service.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Accuracy of this data set is based on the specification of the US Geological Survey GTOPO30 global digital elevation model (DEM). The stated accuracy of the DEM ranges depending on the source of terrain data, but is approximately 130 m circular error with 90% probability.

Process_Description:
It is beyond the scope of this metadata to document the processes involved in generating spatially gridded precipitation using the PRISM model. However, the processes are documented in numerous conference proceedings and journal articles. The references can be found online at <URL:http://www.ocs.oregonstate.edu/prism>.
