Set the aerosol phase function moments to the values specified in the aerosol moments file  

aerosol_moments_file file_name

 
where the file contains one column with arbitrary number of Legendre terms of the phase function. The phase function p(\mu) is

p(\mu)=\sum _{{m=0}}^{{\infty}}(2m+1)\cdot k_{m}\cdot P_{m}(\mu) (1)

where k_{m} is the m'th moment and P_{m}(\mu) is the m'th Legendre polynomial. If not specified, a Henyey-Greenstein phase function is assumed where the asymmetry parameter g is either a default value depending on the aerosol type or it may be specified using aerosol_set_gg. The phase function will be the same for all altitudes and wavelengths. See aerosol_files if more flexibility is wanted. May only be used together with the cdisort or fdisort2 solver in combination with the option disort_icm moments.
