Ion–Molecule Reaction Products as Probes and Precursors for Preparative Mass Spectrometry
Chemistry – A European Journal, Volume 32, Issue 14, 15 April 2026.Ion–molecule reactions in the gas phase of mass spectrometers are important for preparative mass spectrometry because they (1) provide knowledge about the intrinsic reactivity of ions, helping to predict and control their reactivity at interfaces, and (2) generate new complex ions that can be mass selected and deposited on surfaces.

Minor ion composition in the polar ionosphere
Geophysical Research Letters, 1991 Ion composition measurements from the EXOSD Suprathermal Ion Mass Spectrometer (SMS) are presented. Ions other than H+, notably O+, He+, O++ N+ and N++, are found to constitute a significant (>0.1) and at times dominant (>0.5) component of the thermal ion population in the high‐altitude polar ionosphere.

Plasma Wave Experiments in the Polar Ionosphere
Antarctic Record, 1975 Some important points on the plasma wave experiments in the polar ionosphere are indicated. Concrete proposals of the antarctic rocket experiments on the plasma waves are given.

Turbulent boundary layer in the polar ionosphere.
Journal of geomagnetism and geoelectricity, 1990 The interaction between ionosphere and neutral atmosphere at heights of the dynamo-region leads to the development of Alfven mode instability when the convection velocity exceeds the threshold value VΠ≈0.1km/s. The ionospheric Alfven resonator (IAR) plays an important role as an accumulator of turbulent energy.

Journal of Space Weather and Space Climate, 2014 We directly compare the relative GPS scintillation levels associated with regions of enhanced plasma irregularities called auroral arcs, polar cap patches, and auroral blobs that frequently occur in the polar ionosphere.

Cold ions of ionospheric origin observed at the dayside magnetopause and their effects on magnetic reconnection [PDF]
, 2015 Thesis (Ph.D.) University of Alaska Fairbanks, 2015Magnetic reconnection at the dayside magnetopause is one of the most important mechanisms that efficiently transfers solar wind particles, momentum, and energy into the magnetosphere.

Ionospheric Imaging for Canadian Polar Regions
, 2013 Global Navigation Satellite Systems (GNSS) can be exploited as a cost-effective tool to remotely sense the Earth’s ionosphere and investigate its characteristics. This is due to the global coverage and dual frequency data availability offered through worldwide networks of GNSS stations.

Field-aligned currents observed by the OGO 5 and Triad satellites [PDF]
The existence of field-aligned currents in the polar cap boundary layer as a permanent feature of the magnetosphere is investigated. Magnetic field observations from Triad at 800 km altitude and from OGO 5 in the high-altitude magnetosphere are examined.

Ionosphere-thermosphere (IT) response to solar wind forcing during magnetic storms
Journal of Space Weather and Space Climate, 2016 During magnetic storms, there is a strong response in the ionosphere and thermosphere which occurs at polar latitudes. Energy input in the form of Poynting flux and energetic particle precipitation, and energy output in the form of heated ions and ...
