Abstract

The Global Ozone Monitoring Experiment (GOME) on board the ERS-2 satellite is an across-track nadir-viewing spectrometer which measures solar light reflected from the Earth's atmosphere and surface in the UV visible. The cloud retrieval algorithm presented here combines spectral threshold test on GOME's broad-band radiances with the fitting of reflectances to GOME's moderately high resolution spectra in and around the O₂ A band to retrieve cloud- cover fraction, cloud-top height and cloud optical thickness. The algorithm utilizes the latest O₂ spectroscopic data and features dynamical updating procedures to provide global threshold sets of GOME reflectances. Auxiliary information is obtained from GOME measurements of the Ring effect and the degree of polarization of the Earth's radiation field.
