The possible detection of OBrO in the stratosphere

International audience The analysis of spectral residua recorded at night by the balloon-borne AMON (Absorption par Minoritaires Ozone et Nox) UV-visible spectrometer during five stratospheric flights at middle and high latitudes shows that some absorption features remain in the 475-550 nm range, wh...
