FLATLAND95

Two ISS systems were deployed in support of the Flatland project in central Illinois. These systems were used by the investigators at National Oceanographic and Atmospheric Administration's (NOAA) Aeronomy Laboratory in conjunction with a third 915 MHZ wind profiler already located at the University of Illinois at Champaign-Urbana's Flatland observatory to measure boundary layer entrainment velocities. As part of the effort, the data taken during this project will be used to test the effectiveness of deriving convergence from a triangular configuration of wind profilers. The ISS sites provided surface measurements, wind and virtual temperature profiles, and CLASS sounding capability. Over 140 successful CLASS soundings were taken during FLATLAND.
