Lines and continuum sky emission in the near infrared: observational constraints from deep high spectral resolution spectra with GIANO-TNG [PDF]

, 2015
Aims Determining the intensity of lines and continuum airglow emission in the H-band is important for the design of faint-object infrared spectrographs. Existing spectra at low/medium resolution cannot disentangle the true sky-continuum from instrumental

CalFUSE v3: A Data-Reduction Pipeline for the Far Ultraviolet Spectroscopic Explorer

, 2007
Since its launch in 1999, the Far Ultraviolet Spectroscopic Explorer (FUSE) has made over 4600 observations of some 2500 individual targets. The data are reduced by the Principal Investigator team at the Johns Hopkins University and archived at the ...

A Survey of 10-Micron Silicate Emission from Dust around Young Sun-Like Stars [PDF]

, 2003
We obtained low resolution (R = 100) mid-infrared (8-13 micron wavelengths) spectra of 8 nearby young main sequence stars with the Keck 1 telescope and Long-Wavelength Spectrometer (LWS) to search for 10 micron silicate (Si-O stretch) emission from ...

Airglow

Eos, Transactions American Geophysical Union, 1971
The past 4 years have seen the continuation of considerable activity in airglow research. Patterns of changing emphasis are becoming clear, observations are tending to become more selective, and changes in technique have led to regular observations of dayglow, line widths in the nightglow, and observations in the middle and far ultraviolet, detection ...

The First Detections of the Extragalactic Background Light at 3000, 5500, and 8000A (II): Measurement of Foreground Zodiacal Light [PDF]

, 2001
We present a measurement of the absolute surface brightness of the zodiacal light (3900-5100A) toward a fixed extragalactic target at high ecliptic latitude based on moderate resolution (~1.3A per pixel) spectrophotometry obtained with the du Pont 2.5m ...

Space-Based Limb-Imaging Spectrometer for Atmospheric O₂ Airglow Detection

Atmosphere
This paper presents a space-based limb-imaging spectrometer (LIS) for detecting atmospheric O2 airglow; it scans the atmosphere with a vertical range of 10–100 km and has a vertical resolution of 2 km. The LIS’s detection performance needs to be examined

Variability of the Brunt–Väisälä frequency at the OH^∗-airglow layer height at low and midlatitudes [PDF]

Atmospheric Measurement Techniques, 2020
Airglow spectrometers, as they are operated within the Network for the Detection of Mesospheric Change (NDMC; https://ndmc.dlr.de, last access: 1 November 2020), for example, allow the derivation of rotational temperatures which are equivalent to the ...

Automated Detection and Tracking of Equatorial Plasma Bubbles Utilizing Global‐Scale Observations of the Limb and Disk (GOLD) 135.6 nm Data

Earth and Space Science, 2023
Equatorial plasma bubbles (EPBs) are regions of depleted plasma within the ionosphere that form during post‐sunset hours near the magnetic equator. EPBs tend to align with local geomagnetic field lines, extend hundreds of kilometers along geomagnetic ...

Statistical Analysis of the Phase Velocity Distribution of Mesospheric and Ionospheric Waves Observed in Airglow Images Over a 16‐Year Period: Comparison Between Rikubetsu and Shigaraki, Japan

Journal of Geophysical Research: Space Physics, 2018
Atmospheric gravity waves (AGWs) in the mesopause region and medium‐scale traveling ionospheric disturbances (MSTIDs) in the thermosphere from 1999 through 2014 were studied by applying a three‐dimensional spectral analysis technique to airglow images 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 ...
