AB: The study of atmospheric ozone began in academic institutions in Europe in the late 19th and early 20th Centuries. G.M.B. Dobson soon determined the basic geographic and temporal variations of total ozone with a robust total ozone spectrophotometer. Sydney Chapman proposed a photochemical mechanism to explain the presence of ozone. Yet, even in the 1960's and 70's many uncertainties remained in the understanding of the ozone variations observed with ground, balloon, and rocket instruments. At that time the development of artificial satellites offered a new technology to observe the atmosphere and early survey experiments in the US and USSR showed the feasibility of ozone profile soundings. J.V. Dave and C. L. Mateer suggested in 1967 that total ozone might also be measured from space and proposed a dedicated ozone instrument for profile and total ozone. Donald Heath led the development of the Nimbus 4 Backscatter Ultraviolet (BUV) instrument that was produced by H. A. Roeder and colleagues at Beckman Instruments. Very high quality data proved the wisdom of a dedicated instrument. The credibility of the BUV total ozone data led to it's acceptance by the international ozone community as a data source comparable to the Dobson instrument. The nadir-staring BUV, however, added little to prior knowledge of total ozone due to high variability at mid-latitudes. This paper discusses the state of knowledge leading to the development of a satellite instrument to map the spatial and temporal variations of total ozone, the Total Ozone Mapping Spectrometer.
