NO 2 was measured in the stratosphere at night by means of a balloon‐borne spectrometer, pointing at a bright rising star, in the 427 to 452 nm range. The vertical distribution of NO 2 was deduced using the tangent ray technique between 23 and 38 km. The concentration was (6±1.5)×10 9 mol.cm −3 at 25 km, passing through a minimum of (2±1)×10 9 mol.cm −3 at 29 km and rising again up to (4±0.8)×10 9 mol.cm −3 at 32 km.
