Here's an idea: we could use the NetCDF format for this, very much like we do to store PISM's configuration parameters.
PISM's source code would contain a pism_epsg.cdl file like this:
netcdf pism_epsg {
variables:
int epsg_3413 ;
epsg_3413:latitude_of_projection_origin = 90. ;
epsg_3413:scale_factor_at_projection_origin = 1. ;
epsg_3413:straight_vertical_longitude_from_pole = -45. ;
epsg_3413:standard_parallel = 70. ;
epsg_3413:false_northing = 0. ;
epsg_3413:grid_mapping_name = "polar_stereographic" ;
epsg_3413:false_easting = 0. ;
int epsg_3031 ;
epsg_3031:latitude_of_projection_origin = -90. ;
epsg_3031:scale_factor_at_projection_origin = 1. ;
epsg_3031:straight_vertical_longitude_from_pole = 0. ;
epsg_3031:standard_parallel = -71. ;
epsg_3031:false_northing = 0. ;
epsg_3031:grid_mapping_name = "polar_stereographic" ;
epsg_3031:false_easting = 0. ;
int epsg_3057 ;
epsg_3057:grid_mapping_name = "lambert_conformal_conic" ;
epsg_3057:longitude_of_central_meridian = -19. ;
epsg_3057:false_easting = 500000. ;
epsg_3057:false_northing = 500000. ;
epsg_3057:latitude_of_projection_origin = 65. ;
epsg_3057:standard_parallel = 64.25, 65.75 ;
epsg_3057:long_name = "CRS definition" ;
epsg_3057:longitude_of_prime_meridian = 0. ;
epsg_3057:semi_major_axis = 6378137. ;
epsg_3057:inverse_flattening = 298.257222101 ;
int epsg_5936 ;
epsg_5936:latitude_of_projection_origin = 90. ;
epsg_5936:scale_factor_at_projection_origin = 1. ;
epsg_5936:straight_vertical_longitude_from_pole = -150. ;
epsg_5936:standard_parallel = 90. ;
epsg_5936:false_northing = 2000000. ;
epsg_5936:grid_mapping_name = "polar_stereographic" ;
epsg_5936:false_easting = 2000000. ;
int epsg_26710 ;
epsg_26710:longitude_of_central_meridian = -123. ;
epsg_26710:false_easting = 500000. ;
epsg_26710:false_northing = 0. ;
epsg_26710:grid_mapping_name = "transverse_mercator" ;
epsg_26710:inverse_flattening = 294.978698213898 ;
epsg_26710:latitude_of_projection_origin = 0. ;
epsg_26710:scale_factor_at_central_meridian = 0.9996 ;
epsg_26710:semi_major_axis = 6378206.4 ;
epsg_26710:unit = "metre" ;
}
that would be converted into a .nc file by the build system. During initialization PISM would read this file and iterate over all the variables to extract the map from EPSG codes to CF variable attributes. Then this map can be used to fill PISM's output files with appropriate CF-conformant metadata based on the EPSG code found in the input file.
Users would be able to create custom pism_epsg.nc file by editing the .cdl file and running ncgen. They would then be able to tell PISM to use this file by setting a command-line option.
Note that this is not needed to be able to generate lon and lat fields and their _bounds: we just need the EPSG code for that.
