Description

This is a proposed correction for an error in the documents, not a change to the standard. According to the rules, it will be accepted if no-one objects to it in the next three weeks.

The table in Appendix A incorrectly states that flag_values is a string attribute. This is inconsistent with CF 3.5, which says, "The flag_values attribute is the same type as the variable to which it is attached." This error was pointed out by John Stark in April 2007 http://www.cgd.ucar.edu/pipermail/cf-metadata/2007/001614.html and this month by Philippe Poilbarbe on the netCDF email list.

The correction required is as follows:

  • Add "D for the type of the data variable" to the sentence "The Type values are S for string, N for numeric" before the table in Appendix A.
  • Change the type from S to D for flag_values in the table.
  • In the conformance document, add a section:
    3.5 Flags
    Requirements:
    The flag_values attribute must have the same type as the variable to which it is attached.
