STORM-Fronts Experiment Systems Test (STORM-FEST) 15 Minute and Hourly Precipitation Composite Dataset (1992) for the U.S.

The hourly surface composite dataset contains data from those mentioned except for NCDC with additional data from the Nebraska High Plains Climate Network, Wind Profiler Demonstration Network, and the National Weather Service (NWS) Cooperative Network. The 'Composite Format' applies to both the hourly and 15-minute composites with one variation. The hourly composite dataset contains the nominal date and time of observation, whereas the 15-minute composite does not.

The nominal date and time is the nearest top of the hour time for the observation as compared to the actual time of the observation. Most networks actually take the observation about 5-minutes before the hour, but this varies from network to network and station to station in a network. The parameters include nominal date of observation, nominal time of observation, network identifier, station identifier, latitude, longitude, station occurrence, precipitation amount, qualification code, and the quality control flag.

Parameter notes: 1. The nominal date and time differs from actual time. It is the actual time rounded to the nearest hour for the hourly dataset and rounded to the nearest quarter hour for the 15-Minute dataset.

Actual times may vary a few minutes before or after nominal time. Actual times are not included in the dataset. 2. The station occurence is a uniqueness code to separate two different stations that may be co-located in the same latitude/longitude point. 3.

The meaning of the precipitation amounts is determined by the qualification code.
