| Abstract: | The downward and upward fluxes and radiances at the surface and at the top of the atmosphere in the wavelength intervals of 2000-2020 cm-1, 2300-2320cm-1, 18180-18200 cm-1 calculated by the DISORT and LOWTRAN codes, respectively are compared in this paper. The computational accuracy of these two codes is discussed by this comparison. |
