| Abstract: | In the DOS+ISW algorithm (JQSRT,2004,83(3-4): 407-421) for calculating 1-D atmospheric radiation,the discrete ordinate equations were solved by using the Gauss-Seidel iterative method. A lot of steps were iterated before the convergence was established. Though the simultaneous replacement SOR method may be used to speed up the convergence,it is not very effective. A strongly impulsive SOR was proposed to effectively speed up the convergence. The spatial difference scheme in the above-mentioned algorithm was not conservative. A conservative scheme was developed based on the basic method for deducing the step and diamond schemes. |
