  skos:definition "The Harvard Halogen instrument measures ClO and BrO in situ via a two-step process: chemical conversion to Cl and Br atoms via a rapid bimolecular reaction with NO, followed by atomic resonance fluorescence detection of Cl and Br in the vacuum ultraviolet. The instrument is located in the superpod forebody of the ER-2. The flow of ambient air through the instrument is controlled by a single primary bypass duct from which the laminar core is extracted and decelerated into two nested, mirror-image secondary ducts each with two axes for the detection of halogen radical species. The 4-axis design enables multiple ClO and BrO detectors to be present on each flight."@en ;
