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.

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

The full Eta MOLTS dataset covers most of North America east of the Rocky Mountains (up to 574 locations). MOLTS are hourly time series output at selected locations that contain values for various surface parameters and ‘sounding’ profiles at Eta model levels, and are derived from the Eta model output.

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).

Soil Dynamics Research for Greenhouse gas Reduction through Agricultural Carbon Enhancement network in Auburn, Alabama

This study provides data on soil C and N dynamics and subsequent trace gas emissions at the landscape scale. Evaluates effects of landscape and soil management on 1) methane (CH4), nitrous oxide (N2O) and carbon dioxide (CO2) fluxes, 2) soil carbon (C) and nitrogen (N) mineralization and 3) cover crop decomposition and mineralization.

SMT Study for Greenhouse gas Reduction through Agricultural Carbon Enhancement network in St. Paul, Minnesota

We measured the C and N content of soils managed under corn (Zea mays L.)-soybean (Glycine max L.) rotation following 10 and 15 yr of treatments. A conventional tillage (CT) regime employing moldboard and chisel plowing in alternate years was compared with both continuous no-till (NT) and biennial tillage (BT), which employed chisel plowing before soybean only.

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]).

SGP97 Upper Air: DOE ARM 50 MHz Profiler Winds

This data set covers the period from 1 June through 31 July 1997. The SGP97 domain is approximately 97W to 99W longitude and 34.5N to 37N latitude. These data are in their original NetCDF format. The 50-MHz Radar Wind Profiler/RASS (RWP50) measures wind profiles from (nominally) 2 to 12 km and virtual temperature profiles from 2 to 4 km.
