Abstract For this study regional frequency analyses were conducted for precipitation annual maxima in the state of Oregon for the 24-hour duration. A total of 693 precipitation gages in Oregon, southern Washington, western Idaho, northern California and northern Nevada were included in the study, representing 34,062 station-years of record.What types of data are used to calculate rainfall amounts?
Note: Rainfall amounts are estimates and consist of both rain gauge data and radar data.What GIS data is available for precipitation-frequency information?
Electronic gridded datasets are available for use in creation of GIS applications that utilize precipitation-frequency information. A catalog of extreme storms was assembled that lists precipitation events that exceeded a 20-year return period for the various climatic regions.
