The project FDR4ATMOS (Fundamental Data Records in the domain of satellite Atmospheric Composition) has been initiated by the European Space Agency (ESA). A Fundamental Data Record (FDR) is a long-term record of selected Earth observation Level 1 parameters (radiance, irradiance, reflectance), possibly multi-instrument, which provides improvements of performance with respect to the individual mission datasets.

Task A of the project covers the improvement SCIAMACHY of the Level 1b degradation correction, with the aim to remove ozone trends from the SCIAMACHY Level 2 dataset that were introduced during the development of baseline version 9 (dataset not released). Additionally we will provide lunar data. Task A is finished and a new data set was released in July 2024.
