TL;DR: In this paper, a grating optical spectrograph and infrared imager system (OSIRIS) on board the Odin spacecraft is designed to retrieve altitude profiles of terrestrial atmospheric minor species by observing limb-radiance profiles.
Journal ArticleDOI
ETON 2: Quenching parameters for the proposed precursors of O2(b1Σg+) and O(1S) in the terrestrial nightglow
Ian C. McDade,Donal P. Murtagh,R.G.H. Greer,P.H.G. Dickinson,Georg Witt,Jacek Stegman,E. J. Llewellyn,L. Thomas,D.B. Jenkins +8 more
TL;DR: In this paper, the authors used the volume emission profiles of the O 2 (b 1 Σ g + − X 3 Σg t - )( O - O ) Atmospheric Band and the O( 1 S- 1 D) green line to test the hypothesis that both emissions are excited by Barth type mechanisms.
Journal ArticleDOI
Height, structure and displacements of noctilucent clouds
TL;DR: In this article, the results of a photogrammetric analysis of a very bright cloud display with good visibility conditions on August 10-11th, 1958 at Torsta (63.3° N; 14.6° E) in Central Sweden are presented.
Journal ArticleDOI

TL;DR: In this paper, the authors used heterodyne spectroscopy from space to search for molecular oxygen in the interstellar medium using a Swedish-led satellite called Odin, which carries a 1.1 m sub-millimeter dish and a dedicated 119 GHz receiver for the ground state line of O2.
Journal ArticleDOI
ETON 1: A data base pertinent to the study of energy transfer in the oxygen nightglow
R.G.H. Greer,Donal P. Murtagh,Ian C. McDade,P. H. G. Dickinson,L. Thomas,D.B. Jenkins,Jacek Stegman,Edward J. Llewellyn,Georg Witt,D. J. Mackinnon,E. R. Williams +10 more
TL;DR: A comprehensive group of experiments, assembled and flown on a series of Petrel rockets in March 1982 for the primary purpose of investigating the extent to which energy transfer is important in the excitation of the oxygen nightglow, is briefly described in this article.
