[Chem] Wrong unit or comment in chem/VPRM fluxes

[lpilz]

In the following line, either the unit conversion factor is too small by 3 orders of magnitude or the comment concerning the unit conversion is wrong.

mmol/m^2/s = 1e6 mmol/km^2/s = 1e3 mol/km^2/s = 3.6e6 mol/km^2/h

@weiwangncar - Confirming with a frequent user of this module, will update

@jordanschnell Just wanted to check back if there are any updates

Hi All, here the comment is wrong, the actual unit should be micro-mole m-2 s-1, as per reported in Mahadevan et al., 2008. I guess the original code developer was in haste, and since there are no Greek letters in Fortran...

See. Table 2.

In that case, I would suggest changing this to ! For unit conversion from umol/m^2/s to mol/km2/hr
