A SEA SURFACE REFLECTANCE MODEL SUITABLE FOR USE WITH AATSR AEROSOL RETRIEVAL

This document describes an algorithm for the calculation of sea surface reflectance, suitable for use in an AATSR aerosol retrieval. Methods used in, for ex ample, the 6S model of Vermote et al. [1997], from which this one is derived, are typically c on erned with the region from 400 nm to 700 nm. AATSR’s visible channels are from 550 nm to 1 .6 μm, hence new values of parameters must be researched, and previous assumptions re-eval uat d, to create an model suitable for AATSR. Some examples of aerosol retrieval using the new surf ace algorithm are also presented.
