Looks great to me! Thanks for all the hard work!

Odele, Peter and Judith, the proposers, have all previously indicated that this would be an acceptable solution, so I think we now have consensus on the names. Based on the discussion in this thread and our usual wording for standard name definitions I suggest that the following be added to the standard name table:

The quantity applies outside the atmosphere, by default at a distance of one astronomical unit from the Sun, but a coordinate or scalar coordinate variable of distance_from_sun can be used to specify a value other than the default. "Irradiance" means the power per unit area (called radiative flux in other standard names), the area being normal to the direction of flow of the radiant energy.'

A coordinate variable for radiation wavelength should be given the standard name radiation_wavelength. The quantity applies outside the atmosphere, by default at a distance of one astronomical unit from the Sun, but a coordinate or scalar coordinate variable of distance_from_sun can be used to specify a value other than the default. "Irradiance" means the power per unit area (called radiative flux in other standard names), the area being normal to the direction of flow of the radiant energy.'
