! There were problems acquiring the gfs data files for model initialization

! Some of the initialization or boundary condition files are unavailable.



There shall be no EMS gruven for you on Mon Nov 13 13:49:20 2017 UTC

The very first message detected by SETI will be: "Think Globally, Model Locally!"

I kindly request for help. Thx

! There were problems acquiring the gfs data files for model initialization

! Some of the initialization or boundary condition files are unavailable.

It appears to me that you are trying to run on data from 2013. Not all historic data is kept on the operational data servers.
You should try and find the GFS historic archives and manually download from there.
Alternately you can try changing the server settings in the gfs_gribinfo.conf file to where the historic files exist or even better create a clone with a new name and work on that.

Thank you Norulz,

I kindly request to help me on how to modify the gribinfo such that i can get data for initialization and boundary conditions for 2013 up to 2015.
Thank you once again.

Hi Cliffe,

You need to perform a number of steps.
First find the historic grib files. There are a number of places. Also note that for 2013 there are no 0.25 degree gribs.
I suggest https://nomads.ncdc.noaa.gov/data/gfsanl/ for 0.5 degree gribs.

After you download the required gribs (in 3 hour steps), place these in the "grib" folder of your domain.

Next prepare a customized ~/uems/conf/gribinfo/<Name>_gribinfo.conf file. You might best make a copy of gfsp50_gribinfo.conf file
In this file make sure that FREQFH equals the time step of your data. 03 should be good if you use 3 hourly files.
FOR SURE you will need to edit LOCFILE variable to match the naming convention of the downloaded files.

Last step is to have the correct ems_prep options. You will need to set --dset to the name of your custom gribino.conf file. As the files have been pre-downloaded and already exist in the grib folder you must add the option --local to the command line to skip any new download requests.

I think that that more or less does it for the manual approach

You can, of course, create a new gribinfo.conf file to automatically download the reanalysis files of your choice. There are enough explanations included in the file comments to be able to do this.

Dear Norulz,
Thank you very much, you are restoring my hope now. I also kindly request for help on this one.
For the year 2016, i have been using ems_prep --dset gfs --date yyyymmdd --cycle 12:00:24:06. And files in grid folder are of the form yymmdd.gfs.t12z.0p50.pgrb2f0000 up to yymmdd.gfs.t12z.0p50.pgrb2f024.
From the website https://nomads.ncdc.noaa.gov/data/gfsanl/, files are of the form gfsanl_3_yyyymmdd_1200_000.grb.
I kindly inquire whether it is correct to use different grib files for the years 2013 to 2015 as (gfsanl_3_yyyymmdd_1200_000.grb) and then use yymmdd.gfs.t12z.0p50.pgrb2f---- format for 2016.
I will be grateful for the response.
Thank you very much.
Cliffe

I also kindly request to know how i can identify initialization and boundary conditions for my region from the data on this website https://nomads.ncdc.noaa.gov/data/gfsanl/

The files have global coverage. When you run ems_prep it will "take" what it needs.

Thank you very Norulz may God bless you. I also kindly request you not to give up on me. Kindly allow me to ask one more time about this:

If they are all 0.5 degree files - it is just a naming issue. Content of the files should be the same. You can check this by looking at the file inventories using a utility such as wgrib or wgrib2

You will need a info.conf file for each set with the appropriate naming rules and obviously you will not be able to mix the different named files in the same run
