Time-series (1996 to 2012) of total polar ozone mean values over the months of September, October and November as measured by GOME, SCIAMACHY

The SCanning Imaging Absorption spectroMeter for Atmospheric CartograpHY (SCIAMACHY) was an imaging spectrometer on board the Envisat mission.

SCIAMACHY's primary objective was to perform global measurements of trace gases in the troposphere and in the stratosphere. Its large wavelength range was ideally suited for the determination of aerosols, cloud properties and surface reflection were also retrieved.

SCIAMACHY was developed by a trilateral German/Dutch/Belgian activity under the German Aerospace Centre (DLR), Netherlands Space Office (NSO) and Belgian Federal Science Policy Office (BELSPO) contract involving Dornier Satellitensysteme GmbH and Fokker Space.

Data Description

All Envisat SCIAMACHY products, in accordance with ESA Earth Observation Data Policy, are freely available to registered users via FTP. Read more about the available products and the registration process which is required to access them:

Data Tools

Tools available for visualising, processing and analysing Envisat SCIAMACHY data:

Atmospheric Toolbox

The Atmospheric Toolbox (also known as BEAT) is a collection of executable tools and an application programming interface (API) which has been developed to facilitate the utilisation, viewing and processing of ESA GOMOS, MIPAS, SCIAMACHY and GOME data.


SciaL1C Command-line Tool

The SCIAMACHY Calibration and Extraction Tool (SciaL1c) is an application for selecting and applying specific calibrations of SCIAMACHY Level 1b products to the measured spectra.



Auxiliary Data

Auxiliary data from on-ground and in flight sources is sometimes used to help produce data products. Auxiliary data files for SCIAMACHY data products are available to download.

The goal of SCIAMACHY calibration and validation activities was to verify the accuracy and quality of data the instrument acquired. Details are available of the SCIAMACHY Cal/Val Plan, Calibration and Validation Activities.

SCIAMACHY Quality Control Reports

Quality Control is monitoring routinely the status of the spacecraft (payload and platform) and to check if the derived products meet the quality requirements along mission life-time. Product availability, product anomalies, daily and bi-monthly reports and monthly maps are available for SCIAMACHY quality monitoring.
