Resumo
During the period August-September of any year, the entire NAA-São Paulo path is illuminated almost simultaneously at sunrise, resulting in a sharp drop in the phase of the received signal. Using sunrise phase transitions and an assumed night-time reflection height of 90 km, an ozone screening height of 58 km was deduced. A calculation of the wavelength of the photo-detaching radiation, using this value of the screening height yielded a value of λ = 3015 A ̊. © 1970.
