Abstract

Ozone profiles on a global scale can be derived form GOME satellite data by minimzing the difference between the measured and the corresponding simulated spectra as a function of the vertical distribution of O₃. For this purpose the FUll Retrieval Method was developed, which is based on the optimal estimation approach and contains the radiative transfer code GOMETRAN as an essential component. The quality of the Gome ozone profiles is assessed by comparing them with coincident ozonesonde, lidar, and SAGE II measurements. The comparison results show good agreement at mid-latitudes in winter and spring. For measurements performed at low solar zenith angles GOME tends to overestimate the ozone content at the altitude of the ozone maximum and above. This systematic effect is most probably due to errors in the radiometric calibration of the GOME spectra.
