Tafkaa atmospheric correction of hyperspectral data

摘要

We previously developed an algorithm named Tafkaa for remote sensing of ocean color from aircraft and satellite platforms. The algorithm allows quick atmospheric correction of hyperspectral data using lookup tables generated with a modified version of Ahmad & Fraser's vector radiative transfer code. During the past few years we have extended the capabilities of the code. Current modifications include the ability to account for varying solar geometry (important for very long scenes) and view geometries (important for wide fields of view). Additionally, versions of Tafkaa have been made for a variety of multi-spectral sensors, including SeaWiFS and MODIS. Here we present sample results of atmospheric corrections of data from several platforms.
