Thanks for presenting, Oscar.  I recorded a few comments in the Etherpad, and 
I’ll make sure they all get recorded in the final minutes.

One comment I had when reading through the draft is that it looks like your 
discussion around interactions between L3SM and L3NM are incomplete.  In 
Section 5.1, you only list one sub-bullet on how data can be used between the 
models.  Your lead-up to that makes me think there are other potential things 
to consider when using the two models.
