Small fixes

[moritz-g]

1. When we added the aerosol module, we forgot to add the zenodo link to download more aerosol profiles, I fixed this.
2. There was an error in the doc string for the fluxes2heating function, the pre-factor should be g/c_p, not F/c_p. In the code it's correct, only the docstring was wrong.

Thanks for the fixes!
