Hi Jonathan:
Thats a good question. The CF checker (
http://titania.badc.rl.ac.uk/cgi-bin/cf-checker.pl) is much improved since I last looked, and I will add a link to it from my page.
The TDS tool is not a general-purpose CF-1.0 compliance checker, but more of a practical tool that identifies the variables for which it can identify georefrencing coordinate systems, using CF-1.0 or other Conventions that it knows about (COARDS, etc). This accurately indicates what will be viewable in applications like the IDV that use the Netcdf-Java library. It currently only works on griddded data. My goal is to add better messages to indicate how to fix any problems, but that's a long way off.
I would expect the two tools to be complementary, and I will be comparing the output with the CF checker to try to improve my tool.
Regards,
John
