To calculate the absorption and scattering of radiation through LBLRTM

[syroh109]

Absorption due to clouds/aerosols and LOWTRAN5 routines
Absorption due to clouds and aerosols can be computed in LBLRTM by setting the IAERSL flag in the input TAPE5 file (refer to instructions). This flag allows for LBLRTM to utilize the aerosol capabilities of LOWTRAN5.

I would like to calculate the absorption and scattering of radiation through LBLRTM when atmospheric cloud and aerosol information is specified by the user. The information in the document above is not sufficient, and I was unable to find further relevant details, hence reaching out to you. Could you provide more detailed documentation or guidance on how to incorporate the effects of clouds and aerosols in LBLRTM?

The only option available is IAERSL = 5, which is set in Record 1.2 in the TAPE5 file. You will have to provide a file called "in_lblrtm_cld" that contains cloud (or aerosol) optical depths as a function of wavenumber for each of the layers, which must align with the layers specified for the atmosphere. Please see the section in the LBLRTM instructions called "Spectral Absorption by Layer", which provides the details on formatting the required input text data in the file "in_lblrtm_cld". A sample of "in_lblrtm_cld", which illustrates the formatting, is attached here.
