| ==== User defined aerosol ==== |
| |
| The most general method to setup your own aerosol (or cloud) properties is the following: |
| |
| profile_file 1D aer1 your_aerosol1.dat |
| profile_properties aer1 your_aerosol1.cdf interpolate |
| |
| profile_file 1D aer2 your_aerosol2.dat |
| profile_properties aer2 your_aerosol2.cdf interpolate |
| |
| ... |
| |
| This way you may combine as many aerosol species as you need. The profile_file includes mass concentration altitude profiles and particle size. The netcdf profile_properties_files include the aerosol optical properties (extinction, single scattering albedo, phase matrix, Legendre polynomials of phase matrix ... ) and can be generated using e.g. the Mie tool in libRadtran, where you can specify refractive index and size distribution parameters (see examples/MIE_2.INP). Run |
| bin/mie < examples/MIE_2.INP |
| and you may use the output wc.mie.cdf as example for an optical properties file. |
