Performance of Radar Wind Profilers, Radiosondes, and Surface Flux Stations at the Southern Great Plains (SGP) Cloud and Radiation Testbed (CART) Site

The performance of several routinely operating CART central facility indicated that data from the 50- observational systems at the Southern Great Plains (SGP) MHZ system can be used to determine if the winds Cloud and Radiation Testbed (CART) site has been measured by the 915-MHZ system are distorted by signal evaluated. The results of a few specific investigations are returns from migrating birds. Average differences in the shown here for Radar Wind Profilers (RWPs), Radio (north-south) component of the wind measured with the Acoustic Sounding Systems (RASSs), Balloon-Borne 915-MHZ boundary layer profiler (BLP) versus the 50- Sounding Systems (BBSSs), and Energy Balance Bowen MHZ tropospheric profiler (TP) are shown in Figure 1 for Ratio (EBBR) stations (Coulter and Holdridge 1995; the months of June and August. Evidence suggests that Coulter and Martin 1995; Lesht 1995; Wesely et al. 1995). the large differences in August were caused by migratin g
