This issue is associated with the CPT to test / implement CLUBB-MF (MF = mass fluxes) into CAM, in coordination with JPL / UCLA & NCAR (@mikaelwitte, @JulioTBacmeister). For more information, please refer to the main issue at the cam repo here ESCOMP/CAM#181.

The purpose of this issue is to get a primitive working version of CLUBB-MF onto the cam trunk ASAP. I am currently translating Mikaels CLUBB-MF code mods from an older tag to this more recent tag. I've forked / branch off of the latest CLUBB tag here: clubb_release_b76a124.clubb-mf which will contain all of the necessary code mods. I will respond to this thread when the code mods are ready to be merged.

This relates to the CLASP CPT that aims to communicate subgrid heterogeneity in the land model up to the atmosphere. The proposed approach to achieve that is by computing the surface higher order moments that CLUBB needs within the surface model itself (in a way that accounts for heterogeneous surfaces), and pass those into CLUBB where they can then be prescribed.

In order to pass the moments into CLUBB however, there will need to be modifications to the clubb_api that allow additional inputs to be drawn from within camsrfexch.F90. After discussing with others (especially @Katetc, @adamrher, and @gold2718), it doesn't seem that there's a straightforward way to achieve the end goal without touching CLUBB, so as a first step towards implementing this my aim is to develop a method that works within the CLUBB_CESM repo (we'll need this to work in CESM even if it doesn't ultimately wind up on the UWM repo).
