Abstract

Lidar was used to measure wind and PBL depth for a 6 day period from 16 to 21 July 79 as part of CIRCE (the Central Illinois Rainfall Chemistry Experiment). The boundary layer depth was measured from RHI and RTI scans. These measurements compare favorably with the depths observed in Radiosonde temperature soundings. The model of Sroga et al. (1980) was used to measure the speed, direction, and RMS variation of the wind. During the data analysis, an extension to this model was discovered which reduces the random errors in the measurement of the wind component along the lidar beam.
