A method for parameterizations of the absorption of UV radiation by atmospheric ozone is described. Parameterizations are proposed for computer modeling of tropospheric fluxes of UV–A and UV–B radiation and modified fluxes of biologically active UV radiation in medical applications (for the analysis of vitamin D formation and risk of erythema, cancer, and cataracts). The parameterizations allow solution of the UV radiation transfer equations at the only effective spectral point to obtain integral fluxes in the 280–400 nm range (taking into account the spectral factors characterizing biological effects). When using the parameterizations, the characteristic errors in the calculations of the fluxes in the clear and cloudy troposphere are ~ 3–5%. The use of these parameterizations is relevant for fast radiation models, for example for on-line modeling of UV radiation fluxes for medical purposes. This method can be used to improve the accuracy of radiation codes in general atmospheric circulation models, radiation-chemical models, etc.
