"Initial spaceborne ozone (O ) observations started with the BUV (Backscatter Ultraviolet) sensor, a demonstration instrument flown on Nimbus-4 of NASA (launch April 8, 1970; sun-synchronous near-circular polar orbit, perigee = 1092 km, apogee = 1108 km, inclination = 80.1º, period = 107.2 minutes). The BUV instrument consisted of a double monochromator containing all reflective optics and a photomultiplier detector. The double monochromator was composed of two Ebert-Fastie-type monochromators in tandem. The objective was to monitor the vertical distribution and total amount of atmospheric ozone on a global scale by measuring the intensity of UV radiation backscattered by the Earth/atmosphere system during day and night in the spectral band of 25-34 nm. - The new measurement technique of BUV total column ozone data led to it's acceptance by the international ozone community as a possible data source comparable to the Dobson instrument in ground observations."^^ .
