Digital Data Sets of Depth-Duration Frequency of Precipitation for Oklahoma, USGS OFR 99-463.

Metadata Updated: September 4, 2024

These geospatial data sets consist of precipitation stations used in a regional precipitation frequency analysis for Oklahoma. Data were used from precipitation gage stations with at least 10 years of record within Oklahoma and about 50 kilometers into bordering states. Three different rain gage networks provided the data (15-minute, 1-hour, and 1-day). Data were analyzed for seven frequencies (expressed as recurrence intervals of 2-, 5-, 10-, 25-, 50-, 100-, and 500-years) and 12 durations (15-, 30-, and 60-minutes; 1-, 2-, 3-, 6-, 12-, and 24-hours; and 1-, 3-, and 7-days). Precipitation annual maxima (depths) were determined from the station data for each duration for 110 15-minute stations (used for 15-, 30-, and 60-minute durations), 141 hourly stations (used for 1-, 2-, 3-, 6-, 12-, and 24-hour durations), and 413 daily stations (used for 1-, 3-, and 7-day durations). Statistical methods were used to estimate precipitation depths for each duration-frequency at each station. These station depth-duration-frequency estimates were interpolated to produce continuous grids with grid-cell spacing of 2,000 meters. Contour lines derived from these surfaces (grids) were used to produce the maps in the "Depth-Duration Frequency of Precipitation for Oklahoma" by R.L. Tortorelli, Alan Rea, and W.H. Asquith, U.S. Geological Survey Water-Resources Investigations Report 99-4232. Depth-duration-frequency estimates and interpolated surface values are included in the point attribute tables. One geospatial data set is provided for each of the 12 durations.
