Has the GFS model Zygrib uses been upgraded to the new FV3 version?

Hello,
GFS F3 is the only model available I think.
Some modification on the code have been done in XyGrib to benefit of this change and being able to show correct values of data.

For Zygrib, you have to ask on the forum of Zygrib
Bonne journée ou bonne soirée (vous pouvez choisir)
Have a nice day or good night (you can choose)
Guten Morgen oder gute Nacht (Sie können wählen)

Hi,

Just to add some more information:
On June the 12th XyGrib switched to using the FV3 version of GFS (v15.1).
The older version is still available on a parallel NOAA server but we are not using it any more.
The new version, being non-hydrostatic, has some new meteorological parameters. The one most applicable for sailing forecasts is "Reflectivity".
The option to download and display reflectivity for GFS has been added in the v1.2.6 release of XyGrib

Please note that zyGrib still exists and it can be found at zygrib.org

How about add 2 degrees of resolution for GFS models?

Hi,

Something to consider for some future release.
Is it not simpler to get 2 degree gfs gribs from saildocs.com?
