Abstract:
The U.S. Army Topographic Engineering Center (USATEC) maintains the
TEC Radiation/Meteorology Data Base which consists of surface
radiation and meteorological parameters collected using various
ground-based sensors situated on 20-50 foot towers at four sites: (1)
the TEC site at Ft. Belvoir, VA (which consists of a large set of data
from 1983-1989 and a smaller set from 1992 to the present); (2)
... Jornada Experimental Range (USDA) site, Las Cruces, NM. This site is
located in the Chihuahuan Desert and is a designated ISLSCP/NASA
International site for Study of Arid Lands. Data was collected from
1986-1991; (3) the Yuma, AZ Marine Corps Air Station site located in
the Lower Sonoran Desert. Data was collected from 1988 to the
present. The Yuma site is also a USGS Desert Winds site; and (4) Owens
Lake, CA site located in the Sequoia National Forest. Data at this
site was collected from 1992 to the present. All of the data from each
of the Western U.S. sites have 6, 12, and 60 minute records. The
Virginia site has 30 minute records. The data were taken at fixed
sites and were averaged over 0.3 meter circles at the western sites
and 2.5 meter ovals at the Virgina site. The data collected consists
of wind speed and direction, incoming and outgoing short-wave,
long-wave and diffuse radiation, surface and soil temperature, air
temperature, humidity, precipitation, soil moisture and heat flux,
barometric pressure, and sand flux (for the desert sites). The data
were processed using an HP 9000/520 in HP BASIC and are being migrated
to a Sun Sparcstation 1+ using UNIX. Data from the western sites are
received at a Gateway 2000 PC via direct satellite link and
transferred to the Sun.
