Long-lived meteor trails

Solar-Terrestrial Physics, 2019
The paper presents data on long-lived (~20–40 min) meteor trails. We describe a group of soliton-type meteor trails expanding at transonic speeds. Radio sounding data evidences that the latter include ~7–8 min ionization trails.

Morphology of the Excited Hydroxyl in the Martian Atmosphere: A Model Study—Where to Search for Airglow on Mars?

Remote Sensing
Monitoring excited hydroxyl (OH*) airglow is broadly used for characterizing the state and dynamics of the terrestrial atmosphere. Recently, the existence of excited hydroxyl was confirmed using satellite observations in the Martian atmosphere.

Airglow and Aurorae at Dome A, Antarctica [PDF]

, 2012
Despite the absence of artificial light pollution at Antarctic plateau sites such as Dome A, other factors such as airglow, aurorae, and extended periods of twilight have the potential to adversely affect optical observations.

High latitude artificial aurora from EISCAT: An unique phenomenon? [PDF]

, 2001
The EISCAT HF-facility is capable of transmitting up to 210MW of effective radiated power into the ionosphere around 4 MHz. Beam swinging experiments have been undertaken with O- and X-mode transmissions. During O-mode pumping soon after sunset, F-region

Absolute optical calibrations using a simple tungsten bulb: Theory [PDF]

, 2001
The absolute spectral intensity calibration of optical detectors has always been difficult. In the past, this was only possible using expensive sources, which had been cross-calibrated against national standards. We describe a simple theoretical approach
