Short description
The transformation of trace gases in the atmosphere is determined by radical chain reactions initiated by photolysis processes. More detailed assessment and prediction of air quality, therefore, require knowledge of photolysis frequencies. This standard provides photolysis frequencies for tropospheric conditions. To this end, spectral actinic photon flux densities were calculated for a large number of meteorological situations so as to cover typical conditions for Central Europe, with 200 m above sea level taken as the average altitude. The output of the calculation is done for the altitudes 0 m and 1000 m above ground.
