Hello CF community I have been perusing the CF conventions again, particularly the section on Ancillary Data http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.6/ch03s04.html
The conventions make the statement: The nature of the relationship between variables associated via ancillary_variables must be determined by other attributes. The example given provides data variables which reference the same dimensions in the file: thus they data arrays are the same size. However, the conventions do not seem to mandate this. I am interested in the use of the ancillary_variables attribute in real world datasets. Do people have examples they can share of ancillary datasets which: a. reference the same file dimensions as the data variable with the ancillary_variables attribute references b. reference a subset of the file dimensions referenced by the data variable with the ancillary_variables attribute c. reference file dimensions which are not referenced by the data variable with the ancillary_variables attribute I am particularly interested in examples of case c, as I feel this is markedly different from cases a and b and requires a different kind of support if it is in use. many thanks mark _______________________________________________ CF-metadata mailing list CF-metadata@cgd.ucar.edu http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata
