Andros Island, Bahamas
The University of Wisconsin is responsible for the deployment and operation
of several advanced meteorological instruments at the CAMEX-III ground
truth site on Andros Island in the Bahamas. The focus of the ground-based
observations is on the accurate measurement of atmospheric water vapor
in the column of atmosphere above the ground truth site. Analysis
of this data in conjunction with coincident observations from NASA aircraft
and weather satellites will contribute to the improvement of hurricane
prediction by providing validation of the algorithms and models used in
the interpretation of the aircraft and satellite data. The University
of Wisconsin ground-based observations on Andros Island are being made
in close coordination with the Goddard Space Flight Center Scanning Raman
Lidar (SRL) and
the Wallops Island Flight Facility (WFF)
upper air balloon sounding teams.
Several state-of-the-art sensors were deployed by the University of
Wisconsin on Andros Island,
-
an Atmospheric Emitted Radiance Interferometer (AERI)
for continuous boundary layer profiling of temperature and water vapor,
-
a water vapor GPS
for accurate continuous total column measurements,
-
a surface weather station featuring an accurate dewpoint (chilled mirror)
hygrometer provided by Scott Richardson of the University of Oklahoma,
-
an upper air balloon sounding system (CLASS) for measurement of temperature
and water vapor profiles using Vaisala RS80 radiosondes.
The equipment is based in and around the University of Wisconsin research
vehicle which was transported by barge to the island at end of July 1998.
