Maybe I am wrong that we have done exactly this, because I can't find one by searching the help text of standard names, although I haven't spent long on it. However, angstrom_exponent_of_ambient_aerosol_in_air is an example of a quantity where scalar coordinates can optionally be provided to specify the quantity more precisely (relative_humity and air_temperature) and sound_pressure_level_in_air is a quantity whose definition contains a numerical reference value. I'm assuming that solar irradiance is a quantity which usually refers to 1 AU in practice, is it? If in fact it's used just as often for other distances from the sun, then it would be better not to have a default, and to require the distance from the sun to be specified as a coordinate variable, like number_of_days_with_air_temperature_above_threshold, for instance. If 1 AU is the usual distance, but not the only possibility, then having a default with the possibility of overriding it is neater, I think.
