Statistical properties of nonlinear wave signatures in OH and O2 airglow brightness data observed at lower midlatitudes
(Elsevier, 2010-04)
Among 2187 nights of airglow observations of the OH(6-2) and O2b(0-1) bands from Argentina (mainly from El Leoncito, 32°S 69°W), 132 show airglow brightness jumps (ABJs) of short duration (16 min median). ABJs are supposed ...
Stereoscopic imaging of the hydroxyl emissive layer at low latitudes
(Elsevier, 2008-05-04)
The hydroxyl nightglow layer is an excellent tracer of the dynamical processes occurring within the mesosphere. A new stereo-imaging method is applied that not only measures the altitude of the airglow layer but also ...
Unexpected East-West effect in mesopause region SABER temperatures over El Leoncito
(Elsevier, 2017-05)
We find that mesopause region temperatures determined by the SABER instrument on the TIMED satellite during nocturnal overpasses at El Leoncito (31.8°S, 69.3°W) are several kelvins higher when SABER observes from the East ...
Estudo da propagação vertical das ondas de gravidade de pequena escala observadas na Estação Antártica Comandante Ferraz nos anos de 2015 a 2017
(Universidade Federal de Santa MariaBrasilMeteorologiaUFSMPrograma de Pós-Graduação em MeteorologiaCentro de Ciências Naturais e Exatas, 2020-12-09)
This dissertation had the objective of identification and analysis of the vertical propagation conditions and possible sources of the gravity waves observed over the Comandante Ferraz Antarctic Station (EACF: 62.1° S; 58.4° ...
Solar variablity of the daytime atomic oxygen O(¹S) emission in the middle and lower thermosphere.
(The American Geophysical Union, 2004-03-13)
[1] The Wind Imaging Interferometer (WINDII) on board the Upper Atmosphere Research Satellite (UARS) measures winds from the Doppler shifts of airglow emissions, and as a by-product the volume emission rates (photon cm־³ ...
