Remote Sounding of Cirrus Cloud Parameters During Daytime.

Abstract

A numerical scheme has been developed to remove the solar component in the AVHRR 3.7 microns channel for the retrieval of cirrus parameters during daytime. The cloud retrieval scheme described in Ou et al. (1993) has been modified in connection with the removal program. We have applied the removal-retrieval scheme to the AVHRR daytime data, collected during FIRE-I- IFO. Distributions of the retrieved cloud heights and optical depths are comparable to those determined from lidar measurements and from GOES visible and IR channels data reported by Minnis et al. (1990a). Moreover, validation of the algorithm has been performed by using various data sets that were collected during the FIRE-Il-IFO (November -December, 1991) at Coffeyville, Kansas. We have focused on the 5 December case. We demonstrate that the retrieved cirrus cloud temperature, mean effective ice crystal size, and optical depth closely match the values derived from the balloon-borne replicator measurements. (MM)
