Comparison of Multichannel and Two-Satellite Methods for Remote Measurement of Sea Surface Temperature.

摘要

Atmospheric correction of IR satellite data for retrieval of sea surface temperatures (SST) by means of differential absorption can take on two forms. The most popular method utilizes changes in the spectral transmittance of the atmosphere between two or more IR channels (multichannel). The second form employs path length differences in the same spectral band using two satellites. The multichannel and two satellite approaches are applied to coincident imagery and in situ data and compared.
