NCEP/EMC U.S. Gridded Gage Only Daily Precipitation (4 km) 2002-Oct 2006
Listed in National Center for Atmospheric Research
This dataset contains the National Centers for Environmental Prediction (NCEP) Environmental Modeling Center (EMC) 4 KM GRIB gage-only analysis using 24h accumulated ("RFC") dataset.
Description
A prototype, real-time, hourly, multi-sensor National Preciptation Analysis (NPA) has been developed at NCEP in cooperation with the Office of Hydrology (OH). This analysis merges two data sources that are currently being collected in real-time by OH and NCEP.
Hourly digital precipitation (HDP) radar estimates are created by the WSR-88D Radar Product Generator on a 131 X 131 4-km grid centered over each radar site. Data analysis routines, including a bias correction of the radar estimates using rain gage data, have been adapted by NCEP on a national 4-km grid from algorithms developed by OH and executed regionally at NWS River Forecast Centers (RFC). This dataset only contains the NCEP 4 KM GRIB Data gage-only analysis using 24h accumulated ("RFC") data.

Other NCEP 4 KM GRIB Data including gage-only analysis, multi-sensor analysis (gage and unbiased radar), radar estimate (no bias removal) and radar estimate after bias removal are available as independent datasets. Depending on the time period selected, all five types may or may not be available. Please see GCIP/EOP: Surface NCEP Ancillary Catalogue of Available GCIP Precipitation Data (NCEP/EMC).
The format of the files is GRIB. The files are compressed using the UNIX "compress" command and "uncompress" must be used before decoding. This dataset is provided as is and was not quality controlled by UCAR/JOSS.
Beginning 1 Jan 2002, the analysis grid has been changed to conform with the official NWS HRAP grid. File names have also been changed. See the readme provided with this dataset for details.
