SGP97 GCIP/EOP Surface: Precipitation NCEP/EMC 4KM Gridded Data (GRIB) Gage-Only 24h accumulated RFC -2001
The Southern Great Plains 1997 (SGP97) Hydrology Experiment originated from an interdisciplinary investigation, "Soil Moisture Mapping at Satellite Temporal and Spatial Scales" (PI: Thomas J. Jackson, USDA Agricultural Research Service, Beltsville, MD) selected under the NASA Research Announcement 95-MTPE-03. The Global Energy and Water Cycle Experiment (GEWEX) Continental-scale International Project (GCIP) Enhanced Observing Period (EOP) takes place in the Mississippi River basin during 1995-2000. The Mississippi River basin provides a number of watershed areas that are potentially useful for hydrologic focused studies. During this period, there will be a number of Enhanced Seasonal Observing Periods (ESOPs) in various smaller scale areas. The temporal coverage for this dataset is as follows: Begin date: 1995-10-01 00:00:00, End date: 2000-10-01 23:59:59. 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. 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). The format of the files is GRIB. The files are compressed using the UNIX "compress" command and "uncompress" must be used before decoding.

National Center for Atmospheric Research / Earth Observing LaboratoryIntended use
The GCIP scientific objectives are 1) Document the time-space variability of the hydrological and energy budgets at a continental-scale; 2) Develop and validate macro-scale land surface hydrologic models, related high resolution atmospheric models, and coupled hydrologic-atmospheric models; 3) Develop and validate information retrieval schemes incorporating existing and future satellite observations combined with enhanced ground-based observations; and 4) Provide a capability to translate the effects of a future climate change into impacts on water resources on a regional basis.Use limitations
