SGP97 Electronically Scanned Thinned Array Radiometer Quick Look Images

NAL Geospatial Catalog
    The core of the 1997 experiment involves the deployment of the L-band Electronically Scanned Thinned Array Radiometer (ESTAR) for daily mapping of surface soil moisture over an area greater than 10,000 km2 and a period on the order of a month. The region selected for investigation is the best instrumented site for surface soil moisture, hydrology and meteorology in the world. This includes the USDA/ARS Little Washita Watershed, the USDA/ARS facility at El Reno, Oklahoma, the ARM/CART central facility, as well as the Oklahoma Mesonet. The region covered by the experiment is 34.5 to 37 North latitude and 97 to 99 West longitude. The aircraft mapping took place over the period 18 June to 18 July 1997. This dataset presents brightness temperature images from the Electronically Scanned Thinned Array Radiometer (L band passive microwave radiometer)

        SGP97 Sub-Surface: PSU Soil Properties Data (Bulk Density)

        NAL Geospatial Catalog
          The temporal coverage for this dataset is as follows: Begin datetime: 1997-06-01 00:00:00, End datetime: 1997-07-31 23:59:59. Using the volume extracted and the dry weight of the soil extracted, the bulk density was computed; the results obtained from sampling the soil surface layer (0-5 cm) bulk density are provided, and files are all ASCII text.

          SGP97 Surface: DOE ARM Energy Balance Bowen Ratio (EBBR) Data

          NAL Geospatial Catalog
            The temporal coverage for this dataset is as follows: Begin datetime: 1997-06-01 00:00:00, End datetime: 1997-07-31 23:59:59. The Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) program operates a network of 12 Energy Balance Bowen Ration (EBBR) stations at its Southern Great Plains site. EBBR provides 30-min observations of latent and sensible heat flux along with net radiation, atmospheric pressure, bowen ratio, wind speed and direction, and the following parameters at five locations surrounding the sites: soil moisture, soil temperature, soil heat flow, soil heat capacity and soil heat flow at the surface.

            SGP97 Surface: DOE ARM Baseline Surface Radiation Network (BSRN) Radiation Data

            NAL Geospatial Catalog
              The temporal coverage for this dataset is as follows: Begin datetime: 1997-06-01 00:00:00, End datetime: 1997-07-31 23:59:59. The Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) program operates a Baseline Surface Radiation Network (BSRN) station at the Central Facility (located near Lamont, in north-central Oklahoma) of its Southern Great Plains site. BSRN provides 1-min observations of direct-beam normal solar irradiance, downwelling hemispheric diffuse solar irradiance, downwelling hemispheric solar irradiance and downwelling hemispheric infrared irradiance.

              SGP97 GCIP/NESOB-97 Sub-Surface: National Climatic Data Center (NCDC) Daily Soil Temperature Dataset

              NAL Geospatial Catalog
                This dataset was formed by extracting soil temperature 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 Soil Temperature Dataset contains data from approximately 12 stations reporting soil temperature data for the NESOB 1997 time period (01 April 1997 through 31 March 1998) and in a domain slightly beyond that of NESOB 1997 (approximately 94.5W to 102W longitude and 34N to 39.5N latitude).

                US Department of Agriculture Soil Climate Analysis Network (SCAN) site 2027 data, Little River, Tift County, Georgia

                NAL Geospatial Catalog
                  This dataset contains air temperature, relative humidity, precipitation, solar radiation, wind speed, soil temperature, and soil moisture data from the Soil Climate Analysis Network (SCAN) site 2027, "Little River," located in Tift County, Georgia. The dataset links to a National Resources Conservation Service data request form, from which available data can be queried. The data collection site is at an elevation of 350 feet; data has been continuously collected there since 1999-05-19.
