Hi Rich, The problem is that we can't currently write valid GeoTIFF files using these projections. The netCDF-java library can handle data in these projections. The TDS can serve the data over WCS just not if a GeoTIFF response is requested. Updating the GeoTIFF code will require a bit of coding and some digging into the GeoTIFF spec to figure out the appropriate tags. I will toss this over to our GeoTIFF person, Yuan, to see what he thinks.
