Book excerpt: Multichannel sea surface temperatures (MCSST) computed from NOAA 7 AVHRR channels 4 and 5 are compared to sea surface temperatures measured by an aircraft radiometer (PRT-5). This data set was collected in Fall, 1982 off the southern Californian coast. The MCSST was warmer by 0.82 degrees in the area aerosol effects did not offset increasing radiance due to vertically warming air temperature. As aerosols were able to offset the temperature contribution to radiance, the difference between MCSST and PRT-5 SST measurements decreased. Aerosol effects on infrared radiance were qualitatively examined using an atmospheric transmittance model (LOWTRAN 6). Comparing the model and PRT-5 results indicates that below the marine boundary layer, high aerosol extinction caused significant cooling. Above the boundary layer, aerosols scattered and emitted energy, generally decreasing the measured radiance. The emission moderated the decrease by increasing the radiance slightly.
