Dear David: Yes, that will work. Thanks for pointing that out to me.
Is this enhancement going to make it into 1.7 ? I took a look at the 1.7 draft, and it is not in there yet. very respectfully, randy ---------------------------------------- From: "David Hassell" <[email protected]> Sent: Friday, December 20, 2013 4:17 AM To: "Randy Horne" <[email protected]> Cc: "[email protected]" <[email protected]> Subject: Re: [CF-metadata] one data variable is associated with two grid mappings Dear Randy, Will the method accepted in ticket 70 (https://cf-pcmdi.llnl.gov/trac/ticket/70) work for you? "The expanded form of the grid_mapping attribute is required if one wants to store coordinate information for more than one coordinate reference system" Something like this, perhaps: float data_var data_var:grid_mapping = "latitude-longitude: <associated coordinates> geostationary: <associated coordinates>" char latitude-longitude // grid mapping char geostationary // grid mapping All the best, David ---- Original message from Randy Horne (09PM 19 Dec 13) > From: Randy Horne <[email protected]> > Date: Thu, 19 Dec 2013 21:26:20 -0500 > To: "[email protected]" <[email protected]> > X-Mailer: Apple Mail (2.1510) > Subject: [CF-metadata] one data variable is associated with two grid > mappings > > Folks: > > We have a product with a data variable containing 10 degree latitude band statistics (i.e. min, max) derived from observation data whose east/west extents are associated with the field of view of a geostationary satellite (i.e. the recently defined geostationary grid mapping / projection). > > The implication is that this data variable is associated with two different grid mappings (latitude-longitude & geostationary).
