Estimating the cross-sectional sizes of potential solar triggers of near-Sun magnetic switchbacks
Astronomy & AstrophysicsContext. The discovery of near-Sun magnetic switchbacks (SBs) represents a key result of the Parker Solar Probe (PSP) mission. Aims. Several theories and models suggest that near-Sun SBs may be triggered by small-scale transient phenomena occurring in ...

Atmospheric super-rotation in solar system and extra-solar planetary atmospheres [PDF]
, 2014 Super-rotation is a common phenomenon in solar system planetary atmospheres. Out of the four substantial atmospheres possessed by solid bodies in the solar system, the slowly rotating planet, Venus, and moon, Titan, are both well-known to have atmospheres that rotate on average substantially more quickly than does the solid surface underneath. The more

The effects of solar particle events on the middle atmosphere [PDF]
Solar particle events (SPEs) have been investigated since the late 1960's for possible effects on the middle atmosphere. Solar protons from SPEs produce ionizations, dissociations, dissociative ionizations, and excitations in the middle atmosphere.

Long-Term Evolution in Noctilucent Clouds’ Response to the Solar Cycle: A Model-Based Study
AtmosphereNoctilucent clouds (NLC) are sensitive indicators in the upper mesosphere, reflecting changes in the background atmosphere. Studying NLC responses to the solar cycle is important for understanding solar-induced changes and assessing long-term climate ...

Aerosol scattering of ultraviolet sunlight in the tropical maritime atmosphere [PDF]
The effects of atmospheric aerosol scattering on the vertical profile of solar ultraviolet radiation are investigated. Measurements of diffuse and total ultraviolet radiation were made using a rocketborne optical sonde in the marine atmosphere of Antigua.

Mars surface radiation exposure for solar maximum conditions and 1989 solar proton events [PDF]
The Langley heavy-ion/nucleon transport code, HZETRN, and the high-energy nucleon transport code, BRYNTRN, are used to predict the propagation of galactic cosmic rays (GCR's) and solar flare protons through the carbon dioxide atmosphere of Mars. Particle
