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 visiblenear 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.
