[climbfuji]

Is your feature request related to a problem? Please describe.

During the review process of #330, the following items were noted as follow-up work:

• in driver/fvGFS/atmosphere.F90, the logic around lines 2152 is redundant - see https://github.com/NOAA-GFDL/GFDL_atmos_cubed_sphere/pull/330/files/85faba53a23060b301c898a438d3df2c44fb14a3#diff-53ee59c906ed74739c938e8c964c9c4fc6b71627e5cd6a5741e2cdacedfc16ab for details
• in driver/fvGFS/atmosphere.F90, remove comment in line 1615
• revisit the files change in PR Branch dev/emc: convert GFS DDTs from blocked data structures to contiguous arrays #330 and remove all unnecessary block loops (do nb=1,blen ...)

Describe the solution you'd like

See above

Describe alternatives you've considered

Leave things as is - not a good idea, since we will be missing out on expected performance improvements

@climbfuji - did this get addressed in #330 or is it a follow on issue to be addressed?

[climbfuji]

No, this is indeed follow-up work that will hopefully lead to less code and small performance gains. Hopefully someone from EMC can pick this up.

Thanks, we will leave this open.
