Abstract: Abstract The authors present a computationally highly efficient method for the online calculation of photolysis and heating rates, which is especially suited for coupled transport–chemistry models. For this purpose, the spectral range 178.6 nm ≤ λ ≤ 752.5 nm, which is important for photochemistry in the troposphere and middle atmosphere, is divided into eight wavelength bands. For each band a parameterization of its contribution to photolysis and heating rates for a purely absorbing atmosphere is proposed, taking into consideration only ...
