Studying 630 nm atomic oxygen emission sources during strong magnetic storms in the night mid-latitude ionosphere

Solar-Terrestrial Physics, 2019
We analyze significant increases in 630 nm atomic oxygen night emissions during very strong geomagnetic storms, using optical measurements, theoretical modeling, and magnetogram inversion technique (MIT) data.

A Comparison of Einstein A Coefficients for OH Rotational Temperature Measurements Using a Large Astronomical Data Set

Atmosphere, 2019
The Einstein A coefficients are considered to be a significant source of uncertainty in the measurement of OH rotational temperatures. Using simultaneous ground and spaced-based observations of OH emission, five sets of Einstein A ...

Aurora and airglow 1970

Eos, Transactions American Geophysical Union, 1971
The Summer Advanced Study Institute, ‘Aurora and Airglow 1970,’ held at Queen's University, Kingston, Ontario, August 3–1970, was attended by 122 persons from 15 different countries. Through aurora and airglow, atmospheric processes were studied and an effort was made to analyze magnetospheric phenomena.
