Satellite Measurements of Maritime Aerosol Parameters

Abstract

A two-channel analysis has been made of NOAA-6 AVHRR data obtained at Barbados in 1980 in conjunction with multispectral ground truth sunphotometer measurements of the aerosol optical thickness. The AVHRR Channel 1 (0.65 micrometers) and Channel 2 (0.86 micrometers) radiances were used to infer the aerosol optical thickness and the Junge size distribution parameter nu, and were compared with the corresponding ground truth values. The analysis has shown, in spite of uncertainties in the accuracy of both the ground truth and satellite data, that the AVHRR Channel 1 and Channel 2 radiances can provide useful estimates of nu to support the aerosol content estimates previously demonstrated.
