using lblrtm to simulate the radiance of cloudy situation

[zuqian]

I have trouble in the TAPE5 file for a cloudy situation . On the "Clouds and Aerosols" Chapter of lblrtm_instructions , it recommends that we had better input the optical depth of cloud in 'in_lblrtm_cld' file and lblrtm no longer supports the LOWTRN. But how could I get the hyperspectral optical depth of the certain hydrometeor profile? Could you please give me some advise if I want to use the GMI_GPROF date?

Hi, Zuqian

You can try using the LOWTRAN options, but we will not be able to help you if they do not work. I am not familiar with GMI_PROF data. If you send me a listing of the available variables I will be able to determine if there is sufficient information to calculate the cloud optical depths.
