Simulating Bouncing Packets Driven by Ducted Lightning‐Generated Whistlers: Comparison With SAMPEX Observations

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Bouncing packets are quasi‐periodic microbursts separated by the electron bounce period. Solar Anomalous and Magnetospheric Particle Explorer observations revealed relativistic (>1 MeV) inner‐belt bouncing packets with “crown,” “decaying,” and “flat” envelopes.

Efficient and Reliable Solar Panels for Small CubeSat Picosatellites

International Journal of Photoenergy, 2014
CubeSat picosatellites have a limited area of walls for solar cells assembling and the available area has to be effectively shared with other parts, such as planar antennas, optical sensors, camera lens, and access port.

Evolution of Reversed Electron Energy Spectra in Earth’s Radiation Belts Observed by CIRBE

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Following an intense geomagnetic storm (Dst < −150 nT) on 5 November 2023, electron fluxes in the outer radiation belt were reduced by more than three orders of magnitude at energies below ∼700 keV while they were enhanced at ∼1–3 MeV, leading to reversed energy spectra.

Spaceborne Far‐Infrared Signal Simulations Over the Antarctic Plateau With Temperature‐Dependent Ice Cloud Optical Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Longwave cloud radiative effects significantly influence variability in global and regional Earth systems. However, there have been very few, if any, measurements of the far‐infrared (FIR) radiation over the polar regions, where about half of the outgoing longwave radiation is in the FIR spectrum. This motivated the Polar Radiant Energy in the
