Abstract :
The incorrect problem of the ozone height profile retrieval by ground-based measurements of the brightness temperatures in ozone spectral lines has been considered elsewhere only by using recurrence numerical methods based on properly chosen height discretization. Such an approach is mathematically inconsistent and does not allow the true retrieval possibilities to be established. The method based on the Tikhonov´s theory has been worked out in order to solve the problem and numerical simulation in the lines centred at 110.8 and 142.2 GHz. The influence of measurement errors, spectral band width, and channel number in the spectral band on the retrieval of the ozone profile peculiarities at different height levels is investigated
