Seasonal MLT-region nightglow intensities, temperatures, and emission heights at a Southern Hemisphere midlatitude site
We consider 5 years of spectrometer measurements of OH(6–2) and O<sub>2</sub>(0–1) airglow emission intensities and temperatures made near Adelaide, Australia (35° S, 138° E), between September 2001 and August 2006 and compare them with measurements of the same parameters from at the...

| Summary: | We consider 5 years of spectrometer measurements of OH(6–2) and O<sub>2</sub>(0–1)
airglow emission intensities and temperatures made near Adelaide, Australia
(35° S, 138° E), between September 2001 and August 2006 and
compare them with measurements of the same parameters from at the same site
using an airglow imager, with the intensities of the OH(8–3) and O(<sup>1</sup>S)
emissions made with a filter photometer, and with 2 years of Aura MLS
(Microwave Limb Sounder) v3.3 temperatures and 4.5 years of TIMED SABER
(Thermosphere Ionosphere Mesosphere Energetics and Dynamics Sounding of the
Atmosphere using Broadband Emission Radiometry) v2.0 temperatures for the
same site. We also consider whether we can recover the actual emission
heights from the intercomparison of the ground-based and satellite
observations. We find a significant improvement in the correlation between
the spectrometer OH and SABER temperatures by interpolating the latter to
constant density surfaces determined using a meteor radar. |
