Inverting OII 83.4 nm Dayglow Profiles Using Markov Chain Radiative Transfer
George Geddes, Ewan Douglas, Susanna C. Finn +2
Emission profiles of the resonantly scattered OII~83.4~nm triplet can in principle be used to estimate \(\mathrm{O}^+\) density profiles in the F2 region of the ionosphere. Given t…
Evaluation of Ionospheric Densities Using Coincident OII 83.4 nm Airglow and the Millstone Hill Radar
Ewan S. Douglas, Steve M. Smith, Andrew W. Stephan +6
We test the utility of the OII 83.4 nm emission feature as a measure of ionospheric parameters. Observed with the Remote Atmospheric and Ionospheric Detection System (RAIDS) Extrem…
Wavefront Sensing in Space from the PICTURE-B Sounding Rocket
Ewan S. Douglas, Christopher B. Mendillo, Timothy A. Cook +2
A NASA sounding rocket for high contrast imaging with a visible nulling coronagraph, the Planet Imaging Coronagraphic Technology Using a Reconfigurable Experimental Base (PICTURE-B…
