SCIAMACHY Auxiliary Data

Auxiliary data

The SCIAMACHY consolidated datasets result from reprocessing activities where the best available on-ground and in-flight auxiliary information was adopted.

The auxiliary data files used to produce the consolidated datasets are available to download:

Level 1b

Auxiliary Data Files for Level 1b v10 processing:

The SCIAMACHY Level 1 processing baseline version 10 adopts the same aux files of version 8 (below) except for the Level 1 initialization file (SCI_LI1_AX) which was replaced and for the new set of M-factor files provided by the Institute of Environmental Physics (IUP), University of Bremen, Germany.


Auxiliary Data Files for Level 1b v8 processing:

Starting from SCIAMACHY Level 1 processing baseline version 8, the radiometric degradation and etalon corrections are applied via monitoring factors (m-factors) files to the Level 0-1b processing step and enclosed into the Level 1b products. With previous baseline versions, the m-factor correction was performed in the Level 1b-c processing step during the generation of Level 2 products. M-factor files are provided by the Institute of Environmental Physics (IUP), University of Bremen, Germany.

As the degradation correction is already applied, m-factor files for Level 1b versions 8 and 10 products are not relevant for the users of SCIAMACHY data.

SCIAMACHY Level 1b baseline version 8 extracts calibration information for specific in-flight parameters from a calibration database generated in a pre-processing stage by Deutsches Zentrum für Luft- und Raumfahrt e.V. (DLR-IMF), Oberpfaffenhofen, Germany. For some orbits along the mission, suitable entries in the database do not exist (e.g. calibration measurements not yet performed). In these cases, default values for the calibration parameters (Leakage current, Pixel-to-Pixel Gain and Etalon, Spectral calibration, and Solar reference spectra) were extracted from a set of reference auxiliary data files causing slightly reduced quality.

The reference files used for the in-flight calibration are the following:

  • SCI_LK1_AXVD-P20090317_115605_20020920_171219_20021119_185224
  • SCI_SP1_AXVD-P20090927_002246_20020920_203413_20021219_221339
  • SCI_PE1_AXVD-P20090925_204810_20020920_171219_20990101_000000
  • SCI_SU1_AXVD-P20110708_093418_20020920_203413_20021005_221339

Level 2

Auxiliary Data Files for Level 2 SGP v7.1 processing:

The SCIAMACHY Level 2 processing baseline version 7.1 adopts an improved initialization file (SCI_IN__AX) implementing some new and changed parameters. The auxiliary file is now integrated into the processor itself (XML format) and is not distributed separately from the processor.
