Hecht, J.H., Collins, S., Kruschwitz, C., Kelley, M.C., Roble, R.G. and Walterscheid, R.L. (2000). The excitation of the Na airglow from Coqui Dos rocket and ground-based observations. Geophysical Research Letters 27: doi: 10.1029/1999GL010853. issn: 0094-8276.

On February 20 1998 two rockets were launched from Puerto Rico as part of the Coqui Dos campaign. Data from on-board photometers and ground-based data from a Na lidar and an airglow imager allowed an estimate to be made, using both the TIME-GCM and MSIS models, of the branching coefficient &agr; for the Na airglow emission. Assuming the hydrogen density is within the range predicted by the two models the data are consistent with &agr; being less than 0.05. This value is well below a recent theoretical estimate of 0.67 and also below the nominally accepted value of 0.1 derived from previous aeronomic data. ¿ 2000 American Geophysical Union
