Converting a NetCDF file to GeoTIFF using GDAL?
Your netcdf uses a rotated pole grid. GDAL is not able to handle that.
There is a ticket for it: http://trac.osgeo.org/gdal/ticket/4285 which gives some workaround.
GMT has a tool called grdrotater
which should be able to work with rotated poles, but I have not yet used it.
If you are used to GRASS, you can try this workaround:

Did you try to convert it with gdal_translate?
Normally it should work by using one of the two possibilities:
First solution: extract every subdataset manually
gdal_translate -of VRT NETCDF:"RainDays1_1961-1990_LTA_25km.nc":raindays_tmean_abs output_RD.vrt
gdal_translate -of VRT NETCDF:"RainDays1_1961-1990_LTA_25km.nc":lat output_lat.vrt
gdal_translate -of VRT NETCDF:"RainDays1_1961-1990_LTA_25km.nc":lon output_lon.vrt
Second solution: let gdal extract the subdatasets automatically
gdal_translate -of VRT -sds RainDays1_1961-1990_LTA_25km.nc output.vrt
The second solution will extract all subdatasets to separate files.
It may be necessary to include the
-a_srs epsg:4326
flag
