Problems reading Grib files (hsaf / h14)

[user343553]

Hi there!

I have a problem with extracting data from a certain family of grib-1 files:

Files can be found at @ http://hsaf.meteoam.it/ Model H14 (SM-DAS-2).


My M-code:

ds=ncdataset(filename);
avail_keys=ds.variables;

This returns

avail_keys =

    'Vertical_velocity_surface'
    'Absolute_vorticity_surface'
    'Absolute_divergence_surface'
    'Relative_vorticity_surface'
    'lat'
    'lon'
    'time'

Then I'll grabbing the data with

dat_tmp=ds.data(curr_key)

'Lat', 'Lon', 'time' works just fine. However when trying to grab the first 4 variables it get this error message:

Bitmap section length = 105438 != grid length 1280000 (1600,800)Java exception occurred:
java.lang.IllegalStateException: Bitmap section length!= grid length %

Any ideas how to fix this?

ds.size('Vertical_velocity_surface')

returns the following for all 4 variables.

ans =

           1         800        1600
