In Earth's environment, the observed polar outflow rate for O+ ions, the main source of oxygen above gravitational escape energy, corresponds to the loss of ∼18% of the present-day atmospheric oxygen over 3 billion years. However, part of this apparent loss can actually be returned to the atmosphere. Examining loss rates of four escape routes with high-altitude spacecraft observations, we show that the total oxygen loss rate inferred from current knowledge is about one order of magnitude… Expand
Enhanced atmospheric oxygen outflow on Earth and Mars driven by a corotating interaction region
[1] Solar wind controls nonthermal escape of planetary atmospheric volatiles, regardless of the strength of planetary magnetic fields. For both Earth with a strong dipole and Mars with weak remnantExpand
Biogenic oxygen from Earth transported to the Moon by a wind of magnetospheric ions
For five days of each lunar orbit, the Moon is shielded from solar wind bombardment by the Earth’s magnetosphere, which is filled with terrestrial ions. Although the possibility of the presence ofExpand
Oxygen escape from the Earth during geomagnetic reversals: Implications to mass extinction
Abstract The evolution of life is affected by variations of atmospheric oxygen level and geomagnetic field intensity. Oxygen can escape into interplanetary space as ions after gaining momentum fromExpand
Estimating the fate of oxygen ion outflow from the high-altitude cusp
Abstract. We have investigated the oxygen escape-to-capture ratio from the high-altitude cusp regions for various geomagnetic activity levels by combining EDI and CODIF measurements from the ClusterExpand

Do Intrinsic Magnetic Fields Protect Planetary Atmospheres from Stellar Winds?
The accumulation of detailed ion flux measurements from long-lived spacecraft orbiting the solar system’s terrestrial planets have enabled recent studies to estimate the rate of solar wind drivenExpand
Heavy Ion Energization, Transport, and Loss in the Earth’s Magnetosphere
The magnetic field of the Earth acts like a shield against the solar wind, leading to a magnetopause position many planetary radii away from the planet, in contrast to the situation at non- or weaklyExpand
Terrestrial ion circulation in space
Abstract. Observations of the terrestrial ion transport and budget in the magnetosphere are reviewed, with stress on low energy ions in the high-altitude polar region and inner magnetosphere, forExpand
Stellar Ablation of Planetary Atmospheres
[1] We review observations and theories of the solar ablation of planetary atmospheres, focusing on the terrestrial case where a large magnetosphere holds off the solar wind, so that there is littleExpand
Earth's ion upflow associated with polar cap patches: Global and in situ observations
We report simultaneous global monitoring of a patch of ionization and in situ observation of ion upflow at the center of the polar cap region during a geomagnetic storm. Our observations indicateExpand


First measurements of the ionospheric plasma escape from Mars
BEFORE the Phobos mission, the magnetosphere of Mars was relatively unexplored. Basically all data on the charged-particle environment of Mars had come from the Soviet Mars missions (Mars 2, 3, 4 andExpand
Sources of Ion Outflow in the High Latitude Ionosphere
Ion composition observations from polar-orbiting satellites in the past three decades have revealed and confirmed the occurrence of a variety of ion outflow processes in the high-latitude ionosphere.Expand
On the origins of energetic ions in the earth's dayside magnetosheath
Energetic ion events in the Earth's dayside subsolar magnetosheath (0900 - 1300 Local Time) are surveyed using data from the Active Magnetospheric Particle Tracer Explorers/Charge CompositionExpand
Nonthermal escape of the atmospheres of Venus, Earth, and Mars
Atmospheric loss from planetary atmo- spheres is an important geophysical problem with impli- cations for planetary evolution. This is a multidisci- plinary research field that requires an expertiseExpand
Extended magnetic reconnection at the Earth's magnetopause from detection of bi-directional jets
In situ two-spacecraft observations of bi-directional jets at the magnetopause find evidence for a stable and extended reconnection line, and conclude that reconnection is determined by large-scale interactions between the solar wind and the magnetosphere, rather than by local conditions at the Magnetopause.

Bursty energetic oxygen events in the dayside magnetosheath: GEOTAIL observations
Two energetic oxygen ion enhancements with a clear anti-sunward flow were observed in the dayside magnetosheath when GEOTAIL was located at (4.3, 16.3, 0.7) RE on 26 January 1994. The oxygen ionsExpand
ENA emission from nearly-mirroring magnetospheric ions interacting with the exosphere
Abstract Energetic neutral atom (ENA) emission is markedly brightest at the lowest altitudes, because it is there that the density of ambient neutrals strongly increases with decreasing height.Expand
