[CF-metadata] Azimuthal Equidistant Projection

Dear All,

Please accept my apologies for yet another querie.

I have browsed through the documentation to find the way to represent
data in Azimuthal Equidistant Projection, but unfortunately had no
success.

Considering I have two arrays which specifiy the values of my
longitudes and latitudes, how do I represent my data ?

With a simple equidistant cylindrical projection I had the following
notation:

dimensions:
        longitude = x ;
        latitude = y ;
variables:
        float longitude(longitude) ;
                longitude:standard_name = "longitude" ;
                longitude:long_name = "Longitude" ;
                longitude:units = "degrees_east" ;
                longitude:step = "lon_delta" ;
                longitude:valid_min = "lon_min" ;
                longitude:valid_max = "lon_max" ;
                longitude:axis = "X" ;
        float latitude(latitude) ;
                latitude:standard_name = "latitude" ;
                latitude:long_name = "Latitude" ;
                latitude:units = "degrees_north" ;
                latitude:step = "lat_delta" ;
                latitude:valid_min = "lat_min" ;
                latitude:valid_max = "lat_max" ;
                latitude:axis = "Y" ;
        short variable_mean(latitude, longitude) ;
                variable:standard_name = "standard_name" ;
                variable:units = "units" ;
                variable:cell_method = "mean (interval: 1 month)" ;
                variable:scale_factor = "scale_factor" ;
                variable:add_offset = "offset" ;
                variable:valid_min = "valid_min" ;
                variable:valid_max = "valid_max" ;
                variable:missing_value = "missing_value" ;

What do I need to do in order to construct a netCDF file following the
CF conventions for data projected on an azimuthal equidistant
projection.

Many thanks for your help.

Best Regards,
Pepe
