Choptank Experimental Watershed Soil Moisture Network

A network of soil moisture and soil temperature profiles as well as solar radiation and precipitation gages are distributed throughout the central region of the DelMarVa peninsula to capture variability of these parameters to give a broad understanding of agricultural conditions in this domain. Soil profile data is captured at depths of 5, 10, 20, and 50 cm below the surface and recorded hourly at locations on the edges of agricultural fields, not inside the production fields.

Reynolds Creek Experimental Watershed, Idaho (Lysimeter)

Lysimeters are instruments that measure water and/or solute movement in soils. The primary purpose for these lysimeters was to measure evapotranspiration (ET); these data describe changes in soil water during the snow-free season. In addition to measuring changes in total soil water, soil water content profiles and soil temperature profiles were measured within or adjacent to the lysimeters and are reported. Two pairs of soil lysimeters were installed in the RCEW in 1967, one pair at the Lower Sheep Creek climate station (designated the east and west lysimeters), separated, center to center, by 3.6 m, and the other pair at the Reynolds Mountain climate station (designated north and south), separated by 4.7 m. These lysimeters were hydraulic weighing lysimeters in which an inner cylindrical tank containing soil is set within a slightly larger outer cylinder.

Southern Great Plains 1997 (SGP97) Hydrology: United States Geological Survey (USGS) Stream Flow Data

The data collected at USGS gaging stations consist of records of stage and measurements of discharge of streams or canals, and stage, surface area, and contents of lakes or reservoirs. This dataset contains only the USGS stream flow data.

Southern Great Plains 1997 (SGP97) Hydrology: United States Geological Survey (USGS) Daily Reservoir Data

This dataset contains only the USGS reservoir data. For a lake or reservoir, capacity tables giving the contents for any stage are prepared from stage-area relation curves defined by surveys. The application of the stage to the capacity table gives the contents, from which the daily, monthly, or yearly change in contents is computed.

Southern Great Plains 1997 (SGP97) Hydrology: Co-operative Agency Reservoir Data

This dataset contains reservoir data from 26 Co-operative Agency stations within the Enhanced Observing Period (EOP) domain and time period. No additional quality control was performed by the University Corporation for Atmospheric Research/Joint Office for Science Support (UCAR/JOSS).

SGP97 GCIP/NESOB-97 Surface: 15-Minute Precipitation Composite

NAL Geospatial Catalog

This precipitation composite was formed from two data sources (National Climatic Data Center (NCDC) Fifteen Minute Precipitation data (TD 3260), and fifteen minute precipitation extracted from the Department Of Energy (DOE) Atmospheric Radiation Measurement Surface (ARMSFC) five minute surface data).

Southern Great Plains 1997 (SGP97) Model: GEM Model Location Time Series (MOLTS) Derived Soundings

The full GEM MOLTS data set covers most of North America (up to 252 locations). MOLTS are hourly time series output at selected locations that contain values for various surface parameters and `sounding' profiles at GEM model levels and are derived from the GEM model output.

SGP97 Surface: NCDC Summary of the Day COOP Precipitation Data

NAL Geospatial Catalog

The primary thrust of the cooperative observing program is the recording of 24-hour precipitation amounts. The observations are for the 24-hour period ending at the time of observation. Observer convenience or special program needs mean that observing times vary from station to station. However, the vast majority of observations are taken near either 7:00 AM or 7:00 PM local time. The National Weather Service (NWS) Cooperative Observer Daily Precipitation dataset was formed by extracting the daily incremental precipitation values provided in the National Climatic Data Center (NCDC) TD 3200 dataset.

SGP97 Surface: NCDC Summary of the Day COOP Dataset

NAL Geospatial Catalog

This NCDC Co-operative Observer (COOP) dataset contains data from sixty-two stations for the SGP 1997 time period (18 June 1997 through 18 July 1997) and in the SGP 1997 domain (approximately 97W to 99W longitude and 34.5N to 37N latitude). The primary thrust of the cooperative observing program is the recording of 24-hour precipitation amounts, but approximately 55% of the stations also record maximum and minimum temperatures.

SGP97 Upper Air: DOE ARM 915 MHz Profiler Winds

This data set contains hourly average profiles of wind speed and direction, u and v wind components (from the Radar Wind Profiler), and virtual temperature (from the RASS [Radio Acoustic Sounding System]).
