Link is the root URL for an ERDDAP griddap service endpoint. The service responds to OPeNDAP requests and related ERDDAP-specific requests to a gridded dataset. A request starts with this root URL, adds a file type extension, and sometimes a constraint expression to specify a subset of data. Example file type extensions which don't require a constraint are .das, .dds, .html, and .graph. Example file type extensions which do require a constraint are .dods, .nc, .mat, .json, and .htmlTable. Full documentation for ERDDAP API at http://coastwatch.pfeg.noaa.gov/erddap/rest.html",
