Downolading "filtered" files from NOAA

Post by kiavik » 06 Mar 2015 17:21

Hi all,
this is my first post on this forum.
First of all I would to thank all the stuff for the great job and the contribution to the community.
Now let us have a look at my problem :)

I am trying to view with ZyGrib files downloaded directly from NOAA website, here the link:

http://nomads.ncep.noaa.gov/cgi-bin/filter_gfs_0p25.pl

the routine allows the user to choose some zone, level, simulation runs in order to keep files small (it is very useful for Virtual Sailing :)

unfortunately I can not open any downloaded file, for sure I am doing something wrong but I do not know what...

Has anyone experienced my issue?

Regards,
Fabio

Hi,
normal it does not work.
files are grib2 format and zygrib can only read grib1 format.
may be in the future

Hi,
The console tool cnvgrib (from NOAA) can convert grib2 to grib1.
There are compiled versions for different OS on internet.
A+

UCAR's grib2to1 can also convert NOMADS grib2 to grib1 for zyGrib/OpenCPN.
