1.2. Objectives

The scientific algorithms for glint correction have been implemented in a processor which is available as a plugin for the BEAM toolbox. This user manual gives a description of the software, i.e. how to install, how to use the graphical and command-line interfaces, and the input/output products of the processor.

The GLINT processor basically consists of two main parts:

FLINT: The algorithm to compute glint reflection at 865 nm from glint at SWIR and TIR bands of AATSR
AGC: The atmosphere and glint correction algorithm

The FLINT computation is optional and provides a 'FLINT value' (the Glint reflection) as additional neural net input used by the AGC. The AGC can also be run standalone without FLINT input. The FLINT algorithm requires overlapping MERIS/AATSR L1b products as input, the AGC only needs a MERIS product.
