Ag Data Commons migration begins October 18, 2023

The Ag Data Commons is migrating to a new platform – an institutional portal on Figshare. Starting October 18 the current system will be available for search and download only. Submissions will resume after the launch of our portal on Figshare in November. Stay tuned for details!

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).

    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: National Centers for Environmental Prediction (NCEP) Miscellaneous Hourly Precipitation Data

        This dataset contains all hourly precipitation data from the National Centers for Environmental Prediction (NCEP) stations. Stations that reported at standard or incremental times are also included in the various NESOB 1997 precipitation composite datasets. The miscellaneous precipitation dataset contains data from stations in the NESOB 1997 domain (94.5 W to 100.5W longitude and 34N to 39N latitude) and time period (01 April 1997 through 31 March 1998).

        SGP97 GCIP/NESOB Surface: Hourly Surface Meteorological Composite

          This Surface Composite contains data for the ARM/GCIP NESOB 1997 time period (01 April 1997 through 31 March 1998) and for the ARM/GCIP NESOB 1997 domain only. The ARM/GCIP NESOB 1997 domain is approximately 34N to 39N latitude and 94.5W to 100.5W longitude. The ARM/GCIP NESOB 1997 Hourly Surface Composite contains ten metadata parameters and 38 data parameters and flags. The metadata parameters describe the station location and time at which the data were collected.

          SGP97 GCIP/NESOB Surface: National Centers for Environmental Prediction (NCEP) Miscellaneous Daily Precipitation Data

            This dataset contains all daily precipitation data from the National Centers for Environmental Prediction (NCEP) stations. Stations that reported at standard or incremental times are also included in the various NESOB 1997 precipitation composite datasets. The miscellaneous daily precipitation dataset contains data from stations in the NESOB 1997 domain (94.5 W to 100.5W longitude and 34N to 39N latitude) and time period (01 April 1997 through 31 March 1998).

            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)

              Antarctica Soil Climate Research Stations

                Nine long-term soil-climate stations in Antarctica were set up to study the effects of latitude, elevation, and soil age. Stations monitor soil temperature, soil water content, air temperature, relative humidity, solar radiation, and wind (speed and direction). Stations: Bull Pass, Bull Pass East, Don Juan Pond, Granite Harbour, Marble Point, Minna Bluff, Mt. Fleming, Scott Base, Victoria Valley. Information and data presented for each station cover Personnel; Description of Station, Data, and Soils; Graphic Display of Data (HTML); Download Data (daily averages) by Year, (Excel).

                SolarCalQ - Version 1

                  The purpose of the SolarCalQ Version 1 JAVA model is to simulate the spectral quality of incident solar radiation for any location on the globe, down to one minute time steps.
