| Abstract: | An algorithm for estimating global sea surface temperatures (SST) from data obtained from the Moderate Resolution Imaging
Spectroradiometer (MODIS) aboard the Aqua satellite has been developed empirically. Four atmospheric correction models for
MODIS observations are examined, and the effects of ancillary data for corrections are discussed. A nonlinear (NLSST) model
using high-temporal-resolution climatological SSTs as the first guess shows high accuracy and availability. The addition of
a temperature-proportional term to the NLSST model effectively improves the estimate. |
