This file looks like it's from a GFDL model? Based on the names of the<br>
coordinates, and the global attributes "grid_type" and "grid_tile", it<br>
looks like it is a "history" file which is on the model grid and has yet<br>
to be regridded to a lat/lon grid. I'm not a user of the ocean data,<br>
but am working with a GFDL history data file from the atmospheric model<br>
on the cubed-sphere model grid tile4. Be very careful! The grid<br>
coordinates xt_ocean and yt_ocean may need to be mapped into actual<br>
global coordinates. To get a view of the data, have you tried opening<br>
the file in GrADS without using a GrADS ctl file? GrADS is able to open<br>
and view the tile4 file I'm working with, but one must be aware that the<br>
map background that GrADS assigns is not physically correct. Can you<br>
use post-processed "pp" data (if you have this, it should be in a "pp"<br>
subdirectory)? These "pp" data have been put on a physical grid.<br>
I talked with someone here at GFDL who works with ocean data, and he<br>
says Ferret is able to open the datasets he works with...<br>
<br>
Here's an example of what's in a pp/ocean/<a href="http://ocean.static.nc" target="_blank">ocean.static.nc</a> file. Note<br>
how the tracer latitude and longitudes are functions of<br>
yt_ocean,xt_ocean: geolat_t(yt_ocean,xt_ocean) and<br>
geolon_t(yt_ocean,xt_ocean). So the lat and lon are themselves<br>
functions of grid coordinate variables. Here's an example of<br>
two-dimensional lat, lon coordinates:<br>
