A Gridded Hourly Precipitation Data Base for the United States

| DOI: 10.5065/P6BM-VM62

The Climate Prediction Center at NCEP compiled a multi-year gridded hourly precipitation data set over the United States. One of the main goals of the project was to produce a manageable research-quality data set suitable for studies of precipitation variability on timescales ranging from diurnal to interannual. This data set was derived from the hourly observations of approximately 2500 U.S. stations. The observations were gridded, using a modified Cressman scheme, into 2-degree latitude by 2.5-degree longitude boxes.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
