Changes needed for GFS Update 2017?

Hi Ivan
i modified ems with new ungrib.exe program, new Vtable.GFS, and METGRID.TBL.ARW (EMS 3.4.1) but if i use combine GRIB2 files A+B, WRF-EMS crashes. This does not happen if i use gfsp25ptile.

Does it happen to you ?

I have exactly the same problem with the update as apextreme. Tried it on a couple different systems with the same result.

It appears that does not work with NOMADS grib filter at all, but with STRC ptiles does. Segmentation faults with NOMADS tiles (regardless I use only standard set or standard + b).

Soil temperature field is not interpolated good, it gets values of 0 kelvins at places when NOMADS files are used, but does not when STRC files are used.

Something is obviously wrong with NOMADS files. I'm trying to find out what and is there a way to fix this.

OK,

There is new variable in grib filter, called LANDN. If you don't download it, soil temperatures are interpolated from wrong mask. Please include that one in your download and try again. It works for me now.

Don't forget to download new terrestrial data sets for latest geogrid, you will probably want to use them.

There is a new update on uems server: 15.99.5 http://ems3.comet.ucar.edu/uems/releases/
Has anyone tested it?

After update I did experience a number of unexplained run failures but with no log files kept - only the usual email message. Each of these failures started up OK on a retrial. I have no idea what happened.

I am experiencing the same, but I am currently still on 15.99.2. My runs fail, and I do not get any diagnostic messages. Is this problem solved in 15.99.5?
