Total cloud cover var name is changed.
***Note - As of 11/13/2014 12Z cycle the variable SNOD was moved from "pgrb2b" files and into "pgrb2" files for all parallel resolutions.***

SNODsfc is back! :D

Yes and upgrade is postponed to January 2015 so we will not see master files probably up to then (any maybe not even then?)

Must be no spaces inside "gfs-para".

I have empty CSNOWsfc if I use GFS 0.25°to feed my WRF ARW. Anyone else too? :(

Is there a way to download GFS PARA grib files for period that are older than a few days ?
I would like to reforecast some days but the ftpprd.ncep.noaa.gov only contains the last 3 days.

I do not believe so because parallel run is considered as testing product, not operational. I might be wrong though.

Thanks for your response. And what about GFS-PROD ? Do you know a server where to download archives ?

If you need reanalysis I would recommend FNL 0.5°:
http://nomads.ncdc.noaa.gov/data/gfsanl/

As far as I know this is the longest free dataset in that resolution available.

In fact, you can use it only for intialization, and then for boundary input files use normal gfs of gfsptiles. In EMS environment, use something like DSETS=gfs-para%gfsptile to do that (see chapter 7 of users guide).

I hope the service will be available from december, but honestly I don't have any rumors about this.

But I sure will do tests with the new GFS data, so to be ready when the tiling service will be available.
Robert promised 0.25deg ptiles when he finish setting up new server (in about a month from now) :)

I am wondering why we can't use gfs-para for boundary conditions ? Will it be possible with the future version of EMS ?
