Surface Flux Teams |
In addition to the ARM surface flux stations within the SGP study area, investigators collected surface flux and ancillary meteorological data during the SGP intensive field campaign. These are summarized below:
NASA-GSFC/Univ of Arizona
The Univ of Arizona Eddy Correlation system acquired validation data for the ARM EC and Bowen Ratio measurements.
USDA-ARS
The USDA-ARS conducted measurements at three sites within the El Reno facility that were representative of the three main vegetation cover types: winter wheat, Bermuda grass and natural rangeland/prairie. Ancillary measurements included soil temperature, soil heat flux and meteorological observations: wind speed and direction, air temperature, relative humidity, and net and solar radiation. Instrument systems were added to measure soil heat flux, soil temperatures, soil thermal conductivity and moisture in the root zone (approximately the first 1 m of the soil profile). At the three sites radiometric surface temperatures were collected on a continuous basis.
University of Wisconsin
A major focus of this group was to compare a "roving" eddy correlation unit to the different instrumentation running at the various flux stations during the SGP study period, helping to determine which flux stations had problems or at the very least showed large discrepancies with the "roving" system. It also provided a means for reducing variation in net radiation observations caused by differences in net radiometer types/calibrations. They also installed infrared radiometers at as many of the flux sites as possible for recording surface temperature on a continuous basis.
NASA JPL
Main interest was to collect surface flux data during aircraft thermal infrared observations and compare eddy correlation measurements using different instrument types with ground-based thermal infrared observations.
Georgia Tech
Sounding measurements included incoming solar radiation, net radiation, ground heat flux and soil temperature, wind speed and direction, surface pressure, air temperature, and relative humidity .
NOAA/ATDD
This group has been collecting energy and CO2 flux data on a continuous basis at a rangeland site in the Little Washita. Ancillary measurements include net and solar radiation, incoming and reflected PAR, soil temperatures (at 6 levels), ground heat flux, precipitation, surface wetness, surface temperature, air temperature and relative humidity, atmospheric pressure, and soil moisture.
