SCIAMACHY


The SCIAMACHY (SCanning Imaging Absorption SpectroMeter for Atmospheric CHartographY) instrument is a 8 channel grating spectrometer covering the spectral range from the UV to the NIR at moderate spectral resolution. It observes the solar radiation scattered by the atmosphere and reflected on the surface. A special feature of SCIAMACHY is the alternating between limb and nadir measurements, facilitating the measurement of both vertical profiles from the mesosphere down to the upper troposphere at low spatial resolution and the measurement of total columns at high spatial resolution (up to 30 x 60 km2 depending on wavelength and solar elevation). Due to a unique matching between limb and nadir measurements (see animation), the scans can be combined to provide tropospheric columns. Where possible, SCIAMACHY is also performing solar and lunar occultation measurements.

SCIAMACHY was launched on board of ENVISAT on March 1st, 2002 and nadir measurements are available from August 2002 to April 2012.

Using the DOAS method, atmospheric columns of NO2, BrO, SO2, HCHO, OClO, glyoxal, IO, and H2O are retrieved from SCIAMACHY nadir measurements at the IUP Bremen.

More on the instrument, the mission concept and scientific products can be found on the IUP SCIAMACHY page; limb and IR data products are available at the IUP SCIAMACHY data centre. For information on the satellite and other ENVISAT instruments check the ESA ENVISAT page. More SCIAMACHY scientific products can be found at the Institute of Environmental Physics, University of Heidelberg and on the TEMIS web site.
