This new version of COOP HPD with faster automations due updated stations will result in faster access for the public. The data are from 1940 to present, depending upon when each station was installed. These stations, nearly all of which were part of HPD version 1, also known as DSI-3240, were gradually upgraded from paper punch tape data recording systems to a more modern electronic data logger system from 2004-2013. Access to 15-minute data past 2014 was halted. Access restarted in 2025. The 15-min gauge depth time series are processed at NCEI via automated quality control and filtering algorithms to identify and remove spurious observations from noise and malfunctioning equipment, and also those due to natural phenomena such as evaporation and the necessary occasional emptying of the gauge. Data and metadata are ingested on a daily basis and combined in a single integrated dataset. As with the legacy punch paper instrumentation, the electronic loggers record rain gauge depth every 15 minutes. Monthly site visits to each station are still performed, but instead of collecting punched paper (that would subsequently need conversion to a digital record via a MITRON reader), data are downloaded from the station's datalogger to a memory stick and centrally collected at the local Weather Forecast Office (WFO) for all stations in the WFO area. The WFO subsequently combines all data into a single tar file and transfers the data to NCEI via ftp upload nominally each month. This updated 15-Minute dataset includes the historical data from the punch paper era and the recent digital era in order to provide the full period of record for each location. These data are formatted consistent with practices for NCEI Global In-situ datasets. This data set provides precipitation amounts on a 15 minute timescale for stations in the Fischer-Porter network. onGoing NOAA National Centers for Environmental Information Customer Engagement Branch 1-828-271-4800 1-828-271-4876 151 Patton Avenue Veach-Baley Federal Building, Room 468 Asheville NC 28801-5001 USA ncei.orders@noaa.gov https://www.ncei.noaa.gov HTTPS Web Browser NOAA National Centers for Environmental Information (NCEI) NCEI home page with information, data access and contact information. information 8:00 - 6:00 Eastern pointOfContact monthly https://data.noaa.gov/docucomp/image/57398ca5-5209-42e7-b4c4-ba0e9315dc1e NCEI COOP 15-Minute Precipitation JPEG Earth Science > Atmosphere > Precipitation theme Global Change Master Directory (GCMD) Science Keywords 2018 revision Version 8.6 Global Change Data Center, Science and Exploration Directorate, Goddard Space Flight Center (GSFC) National Aeronautics and Space Administration (NASA) https://earthdata.nasa.gov/about/gcmd/global-change-master-directory-gcmd-keywords HTTPS Web Browser Global Change Master Directory (GCMD) Keywords The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

Access to 15-minute data was stopped in 2014 and was restarted in 2025. The product is now known as "COOP Precipitation Data - 15 minute (CPD - 15m)." The previously named HPD network has operated since the middle of the 20th century, providing 15-minute precipitation observations and hourly totals for approximately 2000 stations. It originally consisted of several different weighing rain gauge instruments before F&P gauges, with automated readout recorded on paper tape, were phased into the network in the early 1960s. Small changes in the number of stations have occurred throughout the period of record, but the number of stations remains near 2000. Additional information is available in the ATBD (Algorithm Theoretical Basis Document). Data are provided by each of the 122 NWS Weather Forecast Offices. Monthly site visits are made, data are downloaded to thumb drives and then the volunteer either mails the thumb drive or e-mails the data to the WFO. The WFO then consolidates the data and provides to NCEI's anonymous ftp site in a zip file. These data are in the form of gauge depths collected every 15 minutes. The steps are necessary for assuring the quality of the data.
