We combine in situ measurements from Cluster with high-resolution 557.7 nm all-sky images from South Pole to investigate the spatial and temporal evolution of merging on the dayside magnetopause. Variations of 557.7 nm emissions were observed at a

TEAM (Texas Tech Erosion Analysis Model) is a process-based mathematical model that predicts detachment, movement, and deposition of soil particles associated with wind processes. TEAM also simulates the suspension and movement of dust above and down

We report observations of neutral atoms from the solar wind in the Earth's vicinity with the low-energy neutral atom (LENA) imager on the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) spacecraft. This instrument was designed to be capa

Ionospheric ions are energized to suprathermal energies (10–1000 eV) in the auroral zone. This produces a much larger quantity of escaping O+ ions than would otherwise occur, given typical ionospheric energies. Until recently, only limited work had

We report observations of low energy neutral atoms (LENA) from the solar wind and the ionosphere, obtained by the LENA Imager on the IMAGE spacecraft. The LENA Imager detects and images LENAs arriving at the spacecraft from within a 90° field of vie

Experiments were conducted to determine the flux of dust (particles less than few microns in diameter) under Martian atmospheric conditions for surface of three aerodynamic roughness (z(sub 0)). For smooth surface on Mars (z(sub 0) = 0.00125 cm corre

Intense (10 6 cm −2 sr −1 s −1 ) fluxes of upflowing ENAs from the polar cap have been observed in the energy range 0.1–13 keV (hydrogen assumed) from the Astrid satellite at 1000 km altitude. If a source altitude of 400 km is assumed, the EN

We apply a recently developed dynamic fluid-kinetic (DyFK) model to simulate and investigate the effects of soft auroral electron precipitation and perpendicular ion heating by waves on the plasma outflow along auroral field lines. The DyFK model is
