Algorithm Theoretical Basis Document (ATBD) for A-Classification (A-TC ATBD)

This document describes two modules relevant to the classification of the scene. The ATBD is set up according to the EarthCARE ATBD format and the two modules will be described subsequently in the different relevant sections. The first module is the main classification module identifying water cloud, ice clouds and aerosol regions. The second module deals with the aerosol typing only. In practise, this means that in case of , e.g. the description of the input parameters, first a Table is presented with inputs for the main classification and secondly the Table for the aerosol typing. Both modules can be called from any of the other L2a ATLID algorithms when required, for example, see [A-AER-ATBD]. The context of these algorithms with respect to other EarthCARE algorithms is shown
