Abstract:

The algorithm for interpretation of ground-based measurements of brightness temperature of down-welling microwave radiation in the absorption lines, which are traditionally used for ozone profile remote sensing, is described. The inverse problem is formulated as a multiparameter one with respect to ozone vertical profile (target parameter), and also vertical profiles of temperature, pressure, water vapor, cloud liquid water (controlled interfering parameters). Such an approach gives the possibility to utilize additional measurements of atmospheric parameters in different altitude regions (if available) in any combination and also to take into account physical links between parameters (for example, hydrostatic equation for temperature and pressure). Error estimates for retrieval of ozone average concentration in the layers 22-30, 30-40, 40-50, and 50-60 km are presented for summer and winter conditions (for different atmospheric total water content) and for different scenarios of interpretation of down-welling microwave radiation measurements in ozone absorption line 110 GHz.
