Parameters Values

The method was originally suggested to approximate the average ozone profile with values of the parameters A=400 D.U., B=20000 m, C=5000 m. Even individual integrated ozone profiles seem to be smooth enough for approximation by means of the analytical formula and applied to the database of ozone profiles from WODC for period of 1980-91, it made available a statistical analysis of these parameters with aim to obtain their temporal (seasonal) and geographical variability. Therefore, ozone profiles from selected ozone sounding sites were analyzed. Unfortunately, there were only a few stations covering all the period in the 5^o latitudinal belts, in some of them we have to use even shorter series of ozone sounding or we do not have any sounding available at all. For better estimation of the ozone profile by the formula we used TOMS measurement additionally. Fig. 1 represents the seasonal variability of the parameters for Churchill, Hohenpeissenberg and Payerne, where seasonal and latitudinal dependences are well expressed except the latter for the parameter C that is analyzed with greater error. In Fig. 2 final analysis of the ozone profile parameters is presented for northern hemisphere.
