NCEP/EMC U.S. Gage Only Hourly Precipitation Data

Summary

The Environmental Modeling Center (EMC), a component of the National Centers for Environmental Prediction (NCEP) acquires precipitation reports in near real-time from several thousand sites across the contiguous 48 states of the USA. Approximately 3000 automated, hourly rain gage observations are available in the US via the GOES Data Collection Platform (DCP) administered by the NWS Office of Hydrology (OH). These hourly reports are transmitted continuously throughout the day to NCEP in a SHEF-encoded message. This dataset contains the NCEP Hourly Precipitation Gage Data. This dataset is provided as is and was not quality controlled by NCAR/EOL (formerly UCAR/JOSS).

Archive note

Note: 6 and 26 Feb 2018 hourly gage data are missing.

31 August 2020: Start and end dates/times on the files were updated.

7 January 2021: Files missing from June 1998 were added.
