Calculation of optical characteristics of atmospheric aerosols composed from basic aerosol constituents (the AERCOMP FORTRAN code)
The FORTRAN code AERCOMP (UNIX version) developed at LITMS (Institute of Molecular Physics, Russian Research Center "Kurchatov Institute") by Dr. A.N. Rublev. It allows calculations of the above mentioned (**) aerosol integrated optical properties for more complex, composite aerosol models, in the same format as that for *.dat files from Tables 2,3.
To download and install this software:
The aerocomp.f program uses the following files:
