-:We are coupling the whole GEOS-Chem with BCC-ACGM. So we also use the GCHP interface (e.g. gigc_chunk_mod.F90, although may be an older version), and transfer the State_Met and State_Chm objective between BCC and GC. The difference regards to CESM-GC or WRF-GC as I read from Seb’s and May’s slides is that we turn off HEMCO at this stage and process emissions directly in the model. BCC-GC coupling also does not use MAPL or ESMF as BCC is not build on ESMF.
-:I guess the GC code will add many tags as <tt>defined (CESM)</tt> or <tt>defined (WRF)</tt> in the modules. If so, I suggest a tag of <tt>defined (BCCCSM)</tt> be added together. As all couplings are similar in many ways but (I guess) BCC-GC is more model-specific and requires additional coding, e.g. on emissions and eliminating ESMF dependency, I think this is a good way at this stage, and I will reconcile my changes based on these updates in the near future. This can be further discussed.
