[GRASS-user] error opening netcdf file

[Chiara Scaini]

 hi everybody
 this is my first post :-)

 i'm working with meteo data.
 usually i open netcdf with qgis and then import them in grass, using 
 the r.in.gdal.

 grass/qgis error in command line is:

 Loaded : GdalTools (package: GdalTools)
  100%
 ERROR 4: `/home/cscaini/Desktop/meteo/
 WRF-Puerto/prova.nc' not recognised as a supported file format.

 i have a .nc file that i cannot import,
 so i tryed by command line to investigate what happens
 ncdump -h gives a normal output starting like this:

 netcdf Con-001.res {
 dimensions:
        lon = 151 ;
        lat = 151 ;
        alt = 33 ;
        time = UNLIMITED ; // (25 currently)
 variables:
        float lon(lon) ;
                lon:units = "degrees_east" ;
                lon:description = "longitude. East positive" ;
        float lat(lat) ;
                lat:units = "degrees_north" ;
                lat:description = "latitude. North positive" ;
        float alt(alt) ;
                alt:units = "m" ;
                alt:description = "heights (a.s.l.)" ;
        float time(time) ;
                time:units = "h" ;
                time:description = "time after 0000UTC" ;
 etc etc etc

 but when i try to do a gdalinfo, or translate it into geotiff, this is 
 the message i get:

 cscaini at cscaini-ThinkPad-T400:~/Desktop$ gdal_translate -a_srs WGS84 
 -sds prova2.nc prova-translation
 ERROR 4: `prova2.nc' not recognised as a supported file format.

 GDALOpen failed - 4
 `prova2.nc' not recognised as a supported file format.

 cscaini at cscaini-ThinkPad-T400:~/Desktop$ gdalinfo prova2.nc
 ERROR 4: `prova2.nc' not recognised as a supported file format.

 gdalinfo failed - unable to open 'prova2.nc'.

 does everybody know which could be the problem?
 this file is generated by WRF weather forecast model, and then 
 modified.
 (i attached the file)

 with packages netcdf, gdal, etc, everything should be ok,
 because until today i could manage netcdf without problems directly in 
 grass

 thank you very much :-)
