Reevaluation of a Feasibility Study to Measure the Vibrational Temperature of Nitrogen in the Upper Atmosphere by Chemical Release of Hydrogen Iodide.
Abstract
A reevaluation has been made of a proposed hydrogen iodide (HI) chemical release experiment to measure the vibrational temperature of nitrogen Tv(N2) in the upper atmosphere. Recently reported laboratory measurements of important production and loss mechanisms for N2(H) in the upper atmosphere are considered. A consideration of recently measured temporal and spatial fluctuations in the infrared hydroxyl airglow brought about a revision of the estimate of the minimum measurable Tv(N2) to 1200K. An analysis is also given to the limitations of the experiment by the necessity to consider evaporation from a release of liquid HI. It is concluded that the probability of obtaining meaningful results from the proposed experiment is not high enough to warrant its continuance. (Modified author abstract)
