Validation Structure

SCIAMACHY Validation Structure

The German Contribution to the Validation of SCIAMACHY is part of the international structure of the validation of the atmospheric chemistry instruments on Envisat.

This contribution will be complemented by the validation measurements planned in the framework of the Dutch and Belgian validation activities as well as those planned by ESA and co-ordinated within the ENVISAT Atmospheric Chemistry Validation Team (ACVT). The Atmospheric Chemistry Validation Team has been created to address the validation of MIPAS, GOMOS and SCIAMACHY. The ACVT consists of four subgroups:

• SCIAMACHY Calibration and Verification Team (SCCVT, ACVT subgroup leader: Johannes Frerick)
• Ground-based Measurements and Campaign Database (GBMCD, ACVT subgroup leader: Rob Koopman)
• ENVISAT Stratospheric Aircraft and Balloon Campaign (ESABC, ACVT subgroup leader: Patrick Wursteisen)
• Models and Data Assimilation, Satellite Intercomparisons (MASI, ACVT subgroup leader: Claus Zehner)

The requirements for the validation of SCIAMACHY have been developed by the SCIAMACHY Validation and Interpretation sub-Group (SCIAVALIG) of the SCIAMACHY Science Advisory Group (SSAG). One of the tasks of the SCIAMACHY Science Advisory Group is to give advice and assistance concerning the validation of SCIAMACHY. These activities are co-ordinated by the SCIAMACHY Validation and Interpretation Group. SCIAVALIG consists of an international scientific consortium of representatives of the institutes participating in the validation.

The German validation team established working groups for an optimised coordination of the activities. Four working groups were established reflecting the different expertise needed for validation and available within the German research community:

• Validation by ground based and ship borne Measurements,
   Speaker: Klaus Bramstedt, Univ. Bremen;
• Validation by Measurements from Aircraft Platforms,
   Speaker: Gerhard Ehret, DLR
• Validation by Balloon Borne Measurements,
   Speaker Klaus Pfeilsticker, Univ. Heidelberg
• Validation by independent Satellites Measurements,
   Speaker: M. Weber, Univ. Bremen.
