X ray measurements at the South Atlantic Magnetic Anomaly

Journal of Geophysical Research: Space Physics, 1986
Balloon‐borne experiments using omnidirectional scintillation detectors that measured X ray with energies between 30 and 150 keV in the atmosphere were conducted during 1981 from São José dos Campos‐Brazil (geographic coordinates 23°12′S, 45°51′W and L ∼ 1.13).

Strength and timing of austral winter Angolan coastal upwelling

Scientific Reports
The tropical Angolan upwelling system (tAUS) is a highly productive ecosystem of great socio-economic importance. Productivity peaks in austral winter and is linked to the passage of remotely forced upwelling coastal trapped waves (CTWs), where the ...

The effect of South Atlantic Anomaly on ring current dynamics

The South Atlantic Anomaly (SAA) affects the particle evolution and loss processes in the inner magnetosphere. However, most existing inner magnetosphere models average the north-south loss cone to simplify precipitation calculations, neglecting the SAA's impact.
