Still not able to import big grib-files

Tried to import Grib-data again . Either the files I'm getting are totally wrong ( although it says on the site these are global AVN-gribfiles ) or DA is having trouble importing such large files .

Names of the files are :


gblav.t12z.sf96

and

( I think this one is meant for use with a specialized program, DA gives a range check error here and freezes )


gblav.t12z.pgrbf96


size of these is

28,5 Mb
and 25,3 MB respectively

site where I'm getting the data is :
http://www.emc.ncep.noaa.gov/data/


DAWS starts to import the first file ( gblav.t12z.sf96 ) but simply freezes whilst doing so . Only escape is ctrl-alt-del and "end process
"

I know these are gribfiles because it says so on the site . Do I need to rename them or something else ? Or are these completely the wrong files ??

Hi Rik,

try http://gribs.ocens.net/EastAtlantic.wind.grb.bz2 download the file, unzip it and import it by V0.41 alpha.
Take a map of europe and the color scheme "AWIPS (dark map)".
It works.
More files are here http://www.globalmarinenet.net/grib.htm , scrolling down.

Cheers,
Stefan

Hi Stefan,

yes I already knew these particular files do work . Also the ETA- model gribfiles seem to be working as well on the noaa - server .

http://gribs.ocens.net/EastAtlantic.wind.grb.bz2

http://www.globalmarinenet.net/grib.htm


also only offer wind-data , whereas the noaa-server files seems to be offering the full deal : reason why I wanted to use these files .

Has anyone else found a way to import these large ( because they are global ) AVN-gribfiles ? Or is there any other server where they can be obtained ?

Strangely enough DAWS doesn't have any problems with the ETA-data from the same server .
