New developments in the discrete ordinate method for the resolution of the radiative transfer equation
Abstract
The application of the discrete ordinate method of solving the radiative transfer equation as developed by Wehrse (1985) and Schmidt and Wehrse (1987) to a resonance line in a planetary atmosphere is discussed. It is shown that the construction of a quasianalytical solution to the corresponding matrix diagonalization problem reduces the time calculation and permits the use of more dense discrete frequency and angle grids. A comparison with previous work shows that the present method reduces the computation time by more than a factor of 10 and is more appropriate in all cases.
