General Comment: See Hansen et L. (1995) in T.R. Karl (Ed.) 1995 Long term climate monitoring by GCOS. Kluwer. Also, Climatic Change 31, Nos. 2-4. Climate forcing by strat O3, need low bias & spectrally-resolved (~1nm) solar irradiance. UV monitoring may need higher freq. Confidence: reasonable
Def: :Not firm, but based on a strong heritage of experiments with similar data
