> Dear all,
> I have some changes ready to commit to NEMS trunk. The changes are:
> 1. Current NEMS code can restart from history files, but digital filter
> does not work for this case. The time in GFS clock/alarm is updated to
> allow digital filter work for restart
> 2. Ruiyu found that the sigma level used for cloud initialization needs
> vertical coordicate information ak5 and bk5, but current gsm phys does not
> have ak5,bk5, instead, it uses the ratio of vertical level to compute sigma
> level, which causes reduce PBL clouds. A subroutine is added to read the
> vertical coordinate from grid point model level file, and used to compute
> the sigma level for cloud initialization.
> 3. high frequency output is limited only for cold start
> NEMS ticket is:
> corresponding gsm ticket is:
> The nems branch is at:
> The gsm regression test results are generated, the regression test passed
> on both theia and wcoss. There is no impact on nmm.
> Please let me know if you have any questions. Thanks.
