Paper Abstract

In microwave remote sensing of atmospheric trace gases a retrieval technique described by C. D. Rodgers as optimal estimation has widely been adopted during recent years. We found out some difficulties in applying this method to the analysis of long term groundbased observations due to the large variability of the tropospheric transmission. The corresponding changes of the data quality and the weight of the a priori profile in the inversion algorithm can lead to an artificial correlation between the retrieved profiles and the transmission. In addition an assessment of the inversion only from the error bars of the profile is impossible since they don't respond linearly to the errors of the spectra. It is shown, that an inversion algorithm according to Backus-Gilbert's philosophy will avoid these difficulties.
