Chris, I took a look at http://hfrnet.ucsd.edu:8080/thredds/dodsC/HFRNet/USEGC/6km/hourly/RTV.html I agree that "site_code" should not have units.
The CF document states: "Units are not required for dimensionless quantities. A variable with no units attribute is assumed to be dimensionless. However, a units attribute specifying a dimensionless unit may optionally be included." Indeed, if you run your file through the CF-checker, there are no warnings or errors, only informational messages: Checking variable: site_code ------------------ ------------------ Checking variable: site_lon ------------------ ------------------ Checking variable: procParams ------------------ INFO (3.1): No units attribute set. Please consider adding a units attribute for completeness.
