Tidal Variability in the Lower Thermosphere: Relative Importance of ENSO, QBO, PJO, MJO, and Lyα

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Atmospheric tides in the lower thermosphere play an important role in regulating upper‐atmospheric conditions relevant to space weather. However, their spatial and temporal variability remains poorly understood, apart from seasonal variations. Previous studies have shown that tides can be influenced by meteorological and solar conditions. This

Response of Thermospheric Nitric Oxide (NO) Cooling During Events of Strong Solar Wind Pressure

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Nitric oxide (NO) infrared emissions are a notable indicator for varying thermospheric energy budget during geomagnetic storms while the Interplanetary Magnetic Field (IMF) is southward. In this study, we present the first investigation on the response of NO cooling emissions during northward IMF conditions.

Key Parameters for the Ionospheric Detection of Tsunamis From the 29 July 2025 Kamchatka Event

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract It has been demonstrated that tsunamis generate internal gravity waves (GWs) detectable in the ionosphere within 20–60 min after their generation at the ocean surface. Despite numerous simulation and observation studies on ionospheric signatures of tsunamis, the detection of Co‐tsunamic Ionospheric Disturbances (CTIDs) and distinguishing them ...

International Intercomparison of Primary Photovoltaic Reference Cell Calibrations With Excellent Agreement

Solar RRL, Volume 10, Issue 17, 15 September 2026.
Three leading metrology institutes—PTB, NLR, and AIST—compare their primary calibration methods for photovoltaic reference devices following IEC 60904‐4. Four WPVS solar cells with distinct optical characteristics circulate between laboratories. Despite differing measurement principles, all results agree within stated uncertainties, with maximum ...

Experimental assessment of large mammal population estimates from airborne thermal videography

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Wildlife resource management requires reliable, fast, and affordable methods of surveying wildlife populations to develop and adaptively adjust policies. Thermal video from drones can yield high rates of detection over large areas with relative speed and safety.
