What is OPTSIM?
OPTSIM is a numerical tool dedicated to calculate optical properties in the troposphere from modelled aerosols concentrations fields.

Aerosol Optical Thickness estimation for several wavelengths (all aerosols types) Homogeneous or core-shell mixing for refractive index and optical properties calculations Lidar backscattered signal simulation for direct comparisons with CALIOP and PARASOL satellite level 1 data. OPTSIM is written in Fortran 90 and uses NetCDF model files as inputs

Example of lidar simulator use, [Stromatas et al., 2012]
