Calculation of light field in 3D cylinder cloud for greenhouse gases monitoring via GOSAT

摘要

In this work we suggest a precise calculation method for GOSAT program devoid of shortcomings of existing methods. The algorithm was tested on the plain unidirectional source which already has an exact solution to compare with. In that way the radiuses of mesh cylinders were a much larger than their height. Then we tested an algorithm on finite cylinders mesh and compared the results with Monte-Carlo simulation to be sure of its appropriateness. As a results of our work we got a fast and precise method for the calculation angular radiance with consideration of polarization.
