What is OPTSIM?
OPTSIM is a numerical tool dedicated to calculate optical properties in the troposphere from modelled aerosols concentrations fields.
Source code and documentation
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]
- The documentation in PDF: optsim-guide.pdf
- There is two versions of OPTSIM v1, depending on the CHIMERE aerosol output format:
- For CHIMERE output before v2017, with aerosol in tables as p01AERO, p02AERO etc. (one table per aerosol and per bin): optsim_v1_p01AERO.tar
- For CHIMERE output after v2017, with aerosol in tables as bAERO (one table per aerosol and for all bins): optsim_v1_bAERO.tar
