SGP97 GCIP/EOP Surface: Precipitation NCEP/EMC 4KM Gridded Data (GRIB) Gage-Only Analysis (GAG) 1996-2001

NAL Geospatial Catalog
    This dataset contains the National Centers for Environmental Prediction (NCEP) Environmental Modeling Center (EMC) 4 KM GRIB gage-only analysis ("GAG") data. 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 hourly, 6-hourly, and daily analysis. 6-hourly data are generally available at 00Z, 06Z, 12Z, and 18Z.

    NAL Geospatial Catalog
      This dataset contains the National Centers for Environmental Prediction (NCEP) Environmental Modeling Center (EMC) 4 KM GRIB radar estimate (no bias removal) "RAD" data. 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.

        SGP97 GCIP/NESOB Surface: National Climatic Data Center (NCDC) Daily Evaporation Dataset

          This dataset was formed by extracting evaporation data from the GCIP/Enhanced Seasonal Observing Period 1997 (GCIP/ESOP-97) NCDC Summary of the Day Co-operative Dataset (TD-3200) for the NESOB 1997 area and time of interest. This NCDC Evaporation Dataset contains data from approximately 14 stations reporting evaporation data for the NESOB 1997 time period (01 April 1997 through 31 March 1998, and in the NESOB 1997 domain (approximately 94.5W to 100.5W longitude and 34N to 39N latitude).

          On-Farm Residue Removal Study for Resilient Economic Agricultural Practices in Morris, Minnesota

            Interest in harvesting crop residues for energy has waxed and waned since the oil embargo of 1973. Since the at least the late 1990’s interest has been renewed due to concern of peak oil, highly volatile natural gas prices, replacing fossil fuel with renewable sources and a push for energy independence. The studies conducted on harvesting crop residues during the 1970’s and1980’s focused primarily on erosion risk and nutrient removal as a result early estimates of residue availability focused on erosion control.

            SGP97 GCIP/NESOB Surface: Shortwave and Longwave Radiation Composite

              This composite was developed by the merging of the 30-minute averaged values of Irradiance as derived by University Corporation for Atmospheric Research/Joint Office for Science Support (UCAR/JOSS) from the 20-second values provided by ARM for its 25m MFR station and its SIROS and SIRS stations; the 30-minute averaged values of Irradiance as derived by UCAR/JOSS from the 1-minute values provided by ARM for its BSRN station; and the hourly values provided by HPCN. UCAR/JOSS computed standard deviations for the averaged irradiance data when at least 15 observations were available within the 30-minute averaging interval.

              SGP97 GCIP/NESOB Surface: Skin Temperature Composite

                This Skin Temperature composite was formed from three data sources: the 10m and 25m ARM/Clouds and Radiation Testbed (CART) Multi-Filter Radiometer (MFR) 20 second data, and 30 minute data from the GCIP National Oceanic and Atmospheric Administration (NOAA)/Atmospheric Turbulence and Diffusion Division (ATDD) Little Washita, Oklahoma long term flux monitoring site. This composite was developed by the merging of the 30-minute averaged values of skin temperature as provided by NOAA/ATDD for its Little Washita station and the 30-minute averaged values of skin temperature as derived by University Corporation for Atmospheric Research/Joint Office for Science Support (UCAR/JOSS) from the 20-second values provided by ARM for its 10m and 25m MFR stations. UCAR/JOSS computed standard deviations for the ARM 10m and 25m MFR data when at least 15 observations were available within the 30-minute averaging interval.
