Lack of NetCDF support would be a problem for sure. We wondered about that. Jennifer is trying on Windows and I'm on a Mac.

I have attached the errors I got. They look like the same that you were describing (I tried both with and without the -o flag). I did however remember the work around I used, which was to: 1. import the .nc files into MATLAB 2. Export as GeoTIffs 3. Read the GeoTiffs into GRASS This made sense for me partly because I needed to aggregate daily values to monthly means which I did in step 1, but then never thought much more about why I couldn't import directly into GRASS . Your problem motivated me to look into why I needed this workaround in the first place (which is not much of a workaround unless you have access to MATLAB)… which appears to be that my gdal does not have GMT/netcdf support either (as Markus pointed out yesterday). I am also using WIlliams binaries and frameworks. I agree that more detail in the wiki would be helpful, but I think the first step is to compile to update gdal with GMT/NetCDF support. Perhaps William would be interested? =================================================================================================================================== GRASS ERRORS: GRASS 6.4.1 (latlon):~ > r.in.gdal input=~/Desktop/ppt_SRESA2_mid_annual_down_anomaly.nc output=ppt_SRESA2_mid_annual_down_anomaly ERROR: Projection of dataset does not appear to match current location.

I don't seem to remember having any trouble with gdal (which means that it must have worked!) Are you sure that the NetCDF is Lat Long? What was your error exactly? Is the file too big to share? If not send it to me and I'll take a look. Best, Kirk Kirk R.

Looking at the GDAL info, I think we need to specify some additional metadata, but the GDAL page stops short of giving an example of how to do this. Has anyone imported climate data this way?
