WebJan 1, 1973 · The Mariner 9 Ultraviolet Spectrometer has observed the 2550 Å ozone spectral absorption feature on Mars. This absorption was previously detected in the south polar region by Mariner 7 in 1969. Mariner 9 did not observe ozone at any time in the equatorial region, nor at the south polar cap during its summer season. WebAbstract Absolute absorption cross-sections of ozone have been measured at five temperatures (218–295 K) in the UV wavelength region corresponding to the Hartley and Huggins bands (195–345 nm). The aim is to give to the users, a coherent set of data determined under high resolution. A comparison with previous work has been made.
