Abstract
Standard measurements of total column ozone are made in the ultraviolet portion of the spectrum in the Huggins bands, using wavelengths between 305 and 340 nm. Dobson spectrophotometers (Dobson 1931), Brewer spectrophotometers (Wardle et al. 1963), and M-83 filter ozonometers (Gushchin et al. 1985) are standard ground-based instruments for these ultraviolet total column ozone measurements. They each use wavelength pairs to get a differential absorption between strong and relatively weaker portions of the ozone spectrum.
