Ultrafast Kelvin waves in the MLT airglow and wind, and their interaction with the atmospheric tides [PDF]
Annales Geophysicae, 2018 Airglow and wind measurements from the Brazilian equatorial region were used to investigate the presence and the effects of the 3–4-day ultrafast Kelvin waves in the MLT.

Computing uncertainties in ionosphere‐airglow models: II. The Martian airglow [PDF]
Journal of Geophysical Research: Space Physics, 2012 One of the objectives of spectrometers onboard space missions is to retrieve atmospheric parameters (notably density, composition and temperature). To fulfill this objective, comparisons between observations and model results are necessary. Knowledge of these model uncertainties is therefore necessary, although usually not considered, to estimate the ...

Extraction of Quasi-Monochromatic Gravity Waves from an Airglow Imager Network
Atmosphere, 2020 An algorithm has been developed to isolate the gravity waves (GWs) of different scales from airglow images. Based on the discrete wavelet transform, the images are decomposed and then reconstructed in a series of mutually orthogonal spaces, each of which

On the Origin of Near-Infrared Extragalactic Background Light Anisotropy [PDF]
, 2014 Extragalactic background light (EBL) anisotropy traces variations in the total production of photons over cosmic history, and may contain faint, extended components missed in galaxy point source surveys.

Optical Night-Sky Brightness at Mauna Kea over the Course of a Complete Sunspot Cycle [PDF]
, 1997 We have produced a data base of V-band and B-band night-sky brightness measurements rather evenly spread out over the course of a whole sunspot cycle from September 1985 to August 1996.

Spatiotemporal evolution of radio wave pump-induced ionospheric phenomena near the fourth electron gyroharmonic [PDF]
, 2007 On 12 November 2001, the European Incoherent Scatter (EISCAT) high-frequency (HF) radio wave transmitter facility, operating in O-mode at 5.423 MHz with 550 MW effective radiated power, produced artificial optical rings which appeared immediately at ...

Inversion of Wind and Temperature from Low SNR FPI Interferograms
Remote Sensing, 2023 The temperature and wind in the middle and upper atmosphere can be obtained by recording the Doppler shift and broadening of the airglow emission, which is reflected by the interference ring from a ground-based Fabry–Perot interferometer (FPI) system ...

Characterization of a Double Mesospheric Bore Over Europe [PDF]
, 2017 Observations of a pair of mesospheric bore disturbances that propagated through the nighttime mesosphere over Europe are presented. The observations were made at the Padua Observatory, Asiago (45.9\ub0N, 11.5\ub0E), by the Boston University all-sky ...
