Seismic Wave Detectability on Venus Using Ground Deformation Sensors, Infrasound Sensors on Balloons and Airglow Imagers

open access: yesEarth and Space Science
The relatively unconstrained internal structure of Venus is a missing piece in our understanding of the formation and evolution of the Solar System. Detection of seismic waves generated by venusquakes is crucial to determine the seismic structure of ...

Statistics and variability of the altitude of elves

open access: yesGeophysical Research Letters, 2016
From June 2008 to January 2016 nearly 800 elves have been recorded by a low‐light camera in northeastern Spain. Elves occur in this region mainly over the lower topped cold air mass maritime thunderstorms, peaking from November to January.

Airglow Studies in India [PDF]

open access: yes, 1987
84-101  Airglow radiations in different portions of the eletromagnetic spectrum have been studied in many aspects at middle and high latitude stations, from ground-based observations, rockets and satellites.

OMTI Airglow Temperature Photometer (ATP) at Kototabang, Indonesia

open access: yes, 2014
Optical Mesosphere Thermosphere Imagers (OMTIs) Airglow Temperature Photometer (ATP) Data. The ATP measures airglow rotational temperature and airglow intensity in the mesopause region at 80-100km altitudes through the OH and O2 airglow emission lines.

Origin of [OI] 5577 in the airglow and the aurora

open access: yes, 1959
The distribution of 5577 zenith intensities at stations in the subauroral zone is found to be unimodal with no discontinuity at the visual threshold.

First observation of the Venus UV dayglow at limb from SPICAV/VEX

open access: yesGeophysical Research Letters, 2012
We present the first limb observations of the dayglow emissions by the UV channel of SPICAV aboard Venus Express between October and December 2011. The CO Cameron bands between 180–260 nm and CO2+ doublet at 289 nm are clearly identified for the first ...

A rocket-borne airglow photometer [PDF]

open access: yes, 1977
The design of a rocket-borne photometer to measure the airglow emission of ionized molecular nitrogen in the 391.4 nm band is presented. This airglow is a well known and often observed phenomenon of auroras, where the principal source of ionization is ...

Temporal and latitudinal 5577 Å airglow variations

open access: yes, 1981
From 32 000 [O1] 5577 Å airglow limb observations made between April 1971 and December 1972 from the ISIS-2 satellite, the major temporal and spatial night airglow features have been identified.
