Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract Low‐altitude measurements of energetic electron fluxes offer insight into the dynamics of the radiation belts and plasma sheet. However, distinguishing between key magnetospheric regions–such as inner belt, slot region, outer belt, and plasma sheet–based on low‐altitude data remains challenging, particularly for missions lacking pitch‐angle ...

Tropospheric NO2 Patterns in Eastern Canada Using the First Year of TEMPO Observations
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.Abstract The Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument enables an unprecedented assessment of diurnal and community‐scale variations in tropospheric nitrogen dioxide (NO2) across North America. This study presents the first exploratory analysis of NO2 patterns in eastern Canada, including Ontario, Quebec, and the Atlantic ...

Transitions Toward a Midheavy State of Tropical Convection
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 23, 16 December 2025.Abstract This study analyzes the thermodynamic effects of atmospheric vertical motion recorded in satellite observations to investigate the processes behind the evolution of tropical convection. These processes, difficult to observe directly, are diagnosed from satellite retrievals of precipitation (P) and atmospheric cloud radiative effect (ACRE) with

Electronic system for high power load control [PDF]
, 1980 Parallel current paths are divided into two groups, with control devices in the current paths of one group each having a current limiting resistor, and the control devices in the other group each having no limiting resistor, so that when the control ...

Interferometer mirror tilt correcting system [PDF]
, 1977 An interferometer is described, having several means for automatically adjusting the angular tilt of a reflecting surface in one of two paths to maintain the exit beams from the two paths parallel to each other.
