#95: Development of CF 1.5 Data Model -----------------------------+---------------------------------------------- Reporter: markh | Owner: [email protected] Type: task | Status: new Priority: medium | Milestone: Component: cf-conventions | Version: Resolution: | Keywords: -----------------------------+---------------------------------------------- Comment (by markh): As The auxiliary coordinate is a similar construct I also invite comments on the proposed text. This may help if people would liek to comment on them as a pair. == Auxiliary coordinate construct == An auxiliary coordinate construct provides auxiliary information for interpreting the cells of an ordered list of one or more domain axes of the field. An auxiliary coordinate construct must contain * A coordinate array whose shape is determined by the domain axes in the order listed, optionally omitting any domain axes of size one. The elements of the coordinate array must all be of the same data type (numeric, character or string), but they do not have to be distinct or monotonic. Missing values are not allowed (in CF version 1.5). and may also contain * A boundary coordinate array with all the dimensions, in the same order, as the coordinate array, and a fastest-varying dimension (first dimension in Fortran) equal to the number of vertices of each cell. * Properties serving to describe the coordinates. Auxiliary coordinate constructs correspond to auxiliary coordinate variables named by the coordinates attribute of a data variable in a CF- netCDF file. CF recommends there to be auxiliary coordinate constructs of latitude and longitude if there is two-dimensional horizontal variation but the horizontal coordinates are not latitude and longitude. As for dimension constructs, auxiliary coordinate constructs of different field constructs are independent in the data model. -- Ticket URL: <https://cf-pcmdi.llnl.gov/trac/ticket/95#comment:17> CF Metadata <http://cf-pcmdi.llnl.gov/> CF Metadata This message came from the CF Trac system.
