Fun Idea: format output of mcd as input to libRadtran #37

Closed aaronreichmenberliner closed 6 years ago

I want to calculate the spectral flux at any time/location on Mars. The output of mcd should be sufficient to define an input .INP file for libRadtran.

aymeric-spiga commented 6 years ago

Some fluxes are available in the Mars Climate Database https://github.com/aymeric-spiga/mcd-python/blob/416c472b35cdbc9fd82fe8324acdae123c028f14/mcd.py#L190 that are computed by the radiative transfer of the Global Climate Model, from which the MCD is derived.

Or do you have a specific need?

aaronreichmenberliner commented 6 years ago

Yes I saw that! Super awesome. But I need the spectral irradiance from ~200-2000 nm for my calculations. (“Line by line” I think it is called)

aymeric-spiga commented 6 years ago

Yes this will not be in the MCD. Our GCM uses outputs from line-by-line modeling to define absorption in "channels" so that the radiative transfer in the GCM does not take forever. In that case, it would make sense thus to take the atmospheric state from the MCD and input this in libRadtran. This is a use that some MCD users are doing e.g. when using the MCD in retrievals, trying to fit a synthetic spectra to e.g. spectra measured by orbiting spacecraft

I will close this issue, but if you happen to write a small script to format .INP files for libRadtran, you are welcome to submit a pull request so that I'll include this in the Python part. Thanks!
