[gdal-dev] gdal_rasterize with a NetCDF file?

I'm still fairly new at using GDAL, but I am having trouble burning a
vector image onto a NetCDF file.  I've had success with using
gdal_rasterize to burn a vector onto a GeoTIFF file, but when I try to
burn the same vector onto a NetCDF file, I get an error.

Based on the error, I'm suspecting it's because it doesn't know how to
find the right "band" in the NetCDF File (I want the
"Albedo_with_1400_Local_Time_of_Measurement" subdataset), but although
I've looked at the documentation, I'm not sure how to specify this to

Any help would be much appreciated!  Below is the info.

Here is the command I am trying to run:

/usr/local/FWTools-2.0.6/bin_safe/gdal_rasterize -i -burn 0 -l
"OGRGeoJSON" dummy.json Albedo.nc

And the error I get:

ERROR 5: GDALDataset::GetRasterBand(1) - Illegal band #

/usr/local/FWTools-2.0.6/bin_safe/gdal_rasterize: line 9: 26950
Segmentation fault      $FWTOOLS_HOME/bin/`basename $TARGET` "$@"

Here is the gdalinfo for Albedo.nc:

Corner Coordinates:

And for completeness, the dummy.json file (it's basically a triangle):

        "geometry": {

            "coordinates": [ [
                [ -2000000, -2500000 ],
                [ -2500000, -1400000 ],
                [ -1500000, -1400000 ],
                [ -2000000, -2500000 ]
            ] ]
