This document provides the theoretical basis that hides behind the modules of MAJA processor. MAJA stands
for MACCS-ATCOR Joint Algorithm, where MACCS was the Multi-Temporal Atmospheric Correction and
Cloud Screening software, developed by CNES and CESBIO, and ATCOR is the Atmospheric Correction soft-
ware developed by DLR. MAJA is based on MACCS architecture and includes modules that come from AT-
The MAJA processor is applicable to time series of Sentinel-2, Landsat, Venµs, and Formosat satellites.
This Algorithmic Theoretical Basis Document (ATBD) provides a scientific description of the methods used
within MAJA and some justifications of the choices made, as well as basic validation results.
