The calibration of GOME-2 data

摘要

The GOME-2 spaceborne spectrometers will provide data for the ozone product chain of the EUMETSAT Polar System (EPS), in charge of the monitoring of atmospheric ozone. The accuracy of any geophysical parameter retrieved from the GOME-2 measurements will ultimately be limited by the accuracy of the spectral and radiometric calibration of instrument data. This imposes strong accuracy and stability requirements on the instrument, the calibration activities and the ground processing. In this paper, the processing scheme for the spectral and radiometric calibration of GOME-2 data is presented.
