Yes, the f/Q correction employed in msl12 uses chlorophyll as input to Morel's look-up tables (which are actually interpolated from MERIS wavelengths, btw). The input chlorophyll is computed using the sensor default algorithm (OC4 for SeaWiFS, OC3 for MODIS, etc.). The "exact" nLw is computed as:
nLw_ex = nLw * B0 / B
B = (f/Q) * Gothic_R for observed radiant path geometry (solz, senz, relaz)
B0 = B for solz=0, senz=0, relaz=0
and Gothic_R accounts for fresnel reflection & refraction at the interface. The msl12 implementation is updated from Morel 2002 to include Gordon 2005 and Wang 2006 changes to Gothic_R (references below).
The correction is actually derived through iteration, as we need nLw to compute chlorophyll (i.e., nLw -> chl -> nLw_ex -> chl' -> nLw_ex' -> chl'' -> nLw_ex'').
We are currently providing to all the IOP models Rrs_ex = nLw_ex / <F0>. We save the B0/B term internally, so it is possible to provide to the model(s) Rrs(=Rrs_ex*B/B0). That seems to be what the PML code is designed to expect. Alternatively, the PML code could use Rrs_ex and solz=0, senz=0, relaz=0 as the path geometry, since that is the appropriate geometry (theoretically) for Rrs_ex.
I would stress, though, that this workshop is not intended to be an algorithm shoot-out. It is precisely these kinds of differences that we wish to identify and explore. I think the important question here is whether an IOP model inversion can provide a better B0/B than we can currently produce externally. In principle, probably yes, in practice, ...?
