> Dear sir or madam,

> I'm Marietta Bloch, a student from Hochschule Karlsruhe - University of
> Applied Sciences, Germany. At the moment I am struggling with netCDF. In
> this specific GIS-project I have to display REMO climate data
> (RE_UBA_A1B_D3_MM_WIND_SPEED_1-1200.nc) with an WMS. I decided to use
> ncWMS. My problem is, that ncWMS can't load the data telling me that grid
> can't be null. So my question is how can I give my netCDF file a grid?
> I also tried using GDAL (gdal_translate) to convert the dataset. What I
> noticed:
> 
> gdalinfo tells me my file has two subsets: time_bnds and wind_speed.
> 
> When I do "gdal_translate -of netCDF -sds inputfile.nc outputfile.nc" I get
> two files: one contains the time_bnds (output1.nc) and one contains the
> wind_speed (output2.nc). But every variable which was wind_speed is now
> wind_speed1, wind_speed2...... wind_speed1200. netCDF 4.2 UI tells me it
> has a grid now (wherever it came from). I can load output2.nc into ncWMS.
> and the images on the map are shown correctly, but now the time attribute
> is lost and I have a list containing all the 1200 bands as single layers
> (left side in godiva2).
