Short summary

This paper presents, for the first time, a method for cross-calibration of spectrometers using data from the Global Ozone Monitoring Experiment (GOME) and the Scanning Imaging Absorption Spectrometer for Atmospheric Chartography (SCIAMACHY), which operated concurrently for 10 years. The method addresses key challenges compared with optical imagery calibration and integrates Polarization Monitoring Device data to enhance the accuracy and reliability of the cross-calibration process.
