How valid are NWCSAF inputs? #54

Fogpy uses Reff, COT, and LWP from NWCSAF, to what degree are those valid? For ABI I was considering to use NOAA estimates of the three, but for LWP NOAA uses a parametrisation from Bennartz et al. (2007) that is valid for marine boundary clouds and that, according to Cermak et al. (2011), performs very poorly in fog clouds. For my own understanding, I need to understand how exactly fogpy is using LWP and how this compares to what is described by Cermak et al. (2011).
