Harmonise some canonical units

[larsbarring]

I just saw that for some of the standard names the canonical units use division / notation rather than "inversion -1 notation". Is there a specific reason for this? Else it might be useful to change to the latter.

Here is a table of the ones I have found:

Standard Name	Canonical Units
downwelling_longwave_flux_in_air_assuming_clear_sky_and_reference_mole_fraction_of_ozone_in_air	W/m2
downwelling_longwave_flux_in_air_assuming_reference_mole_fraction_of_ozone_in_air	W/m2
downwelling_shortwave_flux_in_air_assuming_clear_sky_and_reference_mole_fraction_of_ozone_in_air	W/m2
downwelling_shortwave_flux_in_air_assuming_reference_mole_fraction_of_ozone_in_air	W/m2
reference_mole_fraction_of_ozone_in_air	mol/mol
surface_downwelling_longwave_flux_in_air_assuming_clear_sky_and_reference_mole_fraction_of_ozone_in_air	W/m2
surface_downwelling_longwave_flux_in_air_assuming_reference_mole_fraction_of_ozone_in_air	W/m2
surface_downwelling_shortwave_flux_in_air_assuming_clear_sky_and_reference_mole_fraction_of_ozone_in_air	W/m2
surface_downwelling_shortwave_flux_in_air_assuming_reference_mole_fraction_of_ozone_in_air	W/m2
surface_upwelling_longwave_flux_in_air_assuming_clear_sky_and_reference_mole_fraction_of_ozone_in_air	W/m2
surface_upwelling_longwave_flux_in_air_assuming_reference_mole_fraction_of_ozone_in_air	W/m2
surface_upwelling_shortwave_flux_in_air_assuming_clear_sky_and_reference_mole_fraction_of_ozone_in_air	W/m2
surface_upwelling_shortwave_flux_in_air_assuming_reference_mole_fraction_of_ozone_in_air	W/m2
toa_outgoing_longwave_flux_assuming_clear_sky_and_reference_mole_fraction_of_ozone_in_air	W/m2
toa_outgoing_longwave_flux_assuming_reference_mole_fraction_of_ozone_in_air	W/m2
toa_outgoing_shortwave_flux_assuming_clear_sky_and_reference_mole_fraction_of_ozone_in_air	W/m2
toa_outgoing_shortwave_flux_assuming_reference_mole_fraction_of_ozone_in_air	W/m2
upwelling_longwave_flux_in_air_assuming_clear_sky_and_reference_mole_fraction_of_ozone_in_air	W/m2
upwelling_longwave_flux_in_air_assuming_reference_mole_fraction_of_ozone_in_air	W/m2
upwelling_shortwave_flux_in_air_assuming_clear_sky_and_reference_mole_fraction_of_ozone_in_air	W/m2
upwelling_shortwave_flux_in_air_assuming_reference_mole_fraction_of_ozone_in_air	W/m2

Moreover, I also found two more that use the full unit string radian rather rad, which is used elsewhere in the table. Same here, if there is not specific reason for this, I suggest changing these too.

Standard Name	Canonical Units
projection_x_angular_coordinate	radian
projection_y_angular_coordinate	radian

Kind regards,
Lars
