Hi Sami,
The Weather and Climate Toolkit (
http://www.ncdc.noaa.gov/oa/wct ) can
handle curvilinear grids (2D lat/lon coordinate variables) and export
nearest-neighbor resampled lat/lon data to a variety of GIS formats
including ArcInfo ASCII GRID, GeoTIFF and NetCDF 3. The export can be
run from the command-line as well as the user interface.
I tested with your file and noticed that there is a bug in the Toolkit
when exporting data to NetCDF 3 when there is no time coordinate for the
data. I will work on fixing this, but in the meantime you can adjust
your file with a couple of lines of NcML to add a time coordinate. The
other formats should work fine and may be all you need to get the data
into a GIS.
The curvilinear grid support is thanks to the work of Jon Blower, who
developed the code as part of the NcWMS project.
Let me know if you have any questions or feedback.
Thanks,
Steve
