Dear all,

Some new changes are ready to commit. The nems ticket #158:Q2FY17 NEMS-GFS
Benchmark Version by Fang Yang.

Description:

To prepare for Q2FY17 NEMS-GFS implementation, NEMS-GFS has been
extensively tested and compared to non-NEMS GFS. Differences between the
two versions have been either removed or greatly reduced.

Changes in this ticket are:

1) corrections of snow water equivalent depth used by radiation,
2) updates of Rayleigh damping
3) the use of ladj=.true. for semi-implicit adjustment
4) fix phour for digital filter

The corresponding gsm ticket is:

The gsm branch is:

gsm regression test results are changed. Full test passed on wcoss and
theia. There is no impact on NMMB.

Please let Fanglin or me know if you have any questions. If there is no
objection, the changes will be committed to nems trunk tomorrow. Thanks.
