Stratocumulus and Cloud-Free Reflectance from Multi-Spectral Satellite Measurements.
Abstract
A summary of the multi-spectral radiative characteristics of marine stratocumulus clouds and pre-cloud suspended aerosols was compiled for August 1986 over the offshore regions of the North American west coast. NOAA-9 AVHRR data were utilized at Channel 1 visible (0.63 micrometer), Channel 2 red visible/near infrared (0.90 micrometer), Channel 3 near infrared (3.7 micrometers), and Channel 4 thermal infrared (11.0 micrometers) wavelengths. Stratus cloud pixels and cloud-free area pixels were identified within the data set, and average radiation parameters with associated standard deviations were calculated for the two pixel classifications. The Channel 3 radiance values were reduced to reflectances through a unique procedure that removed the emittance from the total radiance using the detected Channel 4 emittance. Keywords: Satellite cloud analysis, Cloud distribution, Aerosol distribution, Cloud microphysics.
