Airglow Derived Measurements of Q-Branch Transition Probabilities for Several Hydroxyl Meinel Bands
Franzen, Christoph; Espy, Patrick Joseph; hofmann, niklas; Hibbins, Robert; Djupvik, Anlaug Amanda (Journal article; Peer reviewed, 2019)Spectroscopic measurements of the hydroxyl (OH) airglow emissions are often used to infer neutral temperatures near the mesopause. Correct Einstein coefficients for the various transitions in the OH airglow are needed to ... -
Observation of Quasiperiodic Structures in the Hydroxyl Airglow on Scales Below 100 m
Franzen, Christoph; Espy, Patrick Joseph; Hibbins, Robert; Djupvik, Anlaug Amanda (Journal article; Peer reviewed, 2018)Gravity waves are known to transport energy and momentum to the middle atmosphere. The breaking processes associated with divergence of fluxes of energy and momentum into the atmosphere occur on scales that cannot be ... -
Optimizing hydroxyl airglow retrievals from long-slit astronomical spectroscopic observations
Franzen, Christoph; Hibbins, Robert; Espy, Patrick Joseph; Djupvik, Anlaug Amanda (Journal article; Peer reviewed, 2017)Astronomical spectroscopic observations from ground-based telescopes contain background emission lines from the terrestrial atmosphere's airglow. In the near infrared, this background is composed mainly of emission from ...
