Paper Abstract

Results will focus on cirrus events which occurred during the ARM FIRE Water Vapor Experiment (AFWEX 2000) and Texas 2002 (TX2002) field campaigns over the Southern Great Plains Cloud and Radiation Testbed site (Oklahoma, USA) on 8 December 2000 and 29 November 2002, respectively. Aircraft measurements were taken from the NPOESS Airborne Sounder Testbed-Interferometer (NAST-I) during AFWEX 2000 and the Scanning-High resolution Infrared Sounder (S-HIS) during TX2002. Surface measurements were acquired by the Atmospheric Emitted Radiance Interferometer (AERI), located at the Central Facility. A second AERI, operating in rapid-scan mode within the University of Wisconsin mobile AERIbago, was available during the Texas 2002 case. Spectral absorption optical depths were retrieved using the high spectral resolution infrared measurements combined with lidar measured cloud boundaries. The spectral variation in each optical depth measurement were used to infer cloud particle effective radius from a database of hexagonal column extinction calculations. Results will compare cloud optical properties from simultaneous below- and above-cloud measurements.
