Current status of SCIAMACHY polarisation measurements

JM Krijger, LG Tilstra

The measured signals by SCIAMACHY are corrected by a Polarisation Correction Algorithm to transform the signals to those that would have been measured for unpolarised light. This is achieved by transforming the signals of seven broadband Polarisation Measurement Devices onboard SCIAMACHY to the fractional Stokes parameters Q and U and interpolating them across the whole wavelength range of SCIAMACHY. At the moment of this report the fractional Stokes parameters Q and U as determined by the data-processor show unphysical values, except for the two Polarisation Measurement Devices at the shortest wavelength, as shown by a comparison with GOME polarisation measurements.
