SCIA-Visie

Calibration/Validation of SCIAMACHY data products

SCIAMACHY - SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY - is a passive remote sensing spectrometer observing the Earth in the spectral range 240-2380 nm. The instrument was launched on board ENVISAT which was operational from March 2002 to April 2012. The primary scientific objective of SCIAMACHY is the global measurement of various trace gases in the troposphere and stratosphere. The large wavelength is also ideally suited for the determination of aerosols, clouds, and radiative fluxes. Validation of SCIAMACHY is essential to ensure the quality of these derived products.

The Dutch project SCIA-Visie aims at calibration/validation of SCIAMACHY data products, and is the national contribution to the international SCIAMACHY Quality Working Group. The project is performed by SRON and KNMI, and funded by NSO.  KNMI is performing validation of L1 data and of L2 products, like ozone, NO2, CO, clouds and aerosols.
