Radiation Analysis of LEO Mission in the South Atlantic Anomaly During Geomagnetic Storm

Kirolosse M. Girgis et al.

Summary: The radiation environment of LEO spacecraft passing through the South Atlantic Anomaly during a geomagnetic storm event in May 2005 was studied. It was found that during the recovery phase of the geomagnetic storm, the southern proton flux in the SAA increased, resulting in significantly higher SEU rates and absorbed radiation doses.

East-West Proton Flux Anisotropy Observed with the PAMELA Mission

A. Bruno et al.

Summary: This study investigated the east-west anisotropy of trapped-proton fluxes in low-Earth orbit based on measurements from the PAMELA experiment, revealing that the intensity of eastward fluxes tends to exceed that of westward fluxes in the South Atlantic Anomaly region.

Non-monotonic growth and motion of the South Atlantic Anomaly

Hagay Amit et al.

Summary: The South Atlantic Anomaly (SAA) is a region on Earth's surface with a particularly low intensity of the magnetic field. Accurate characterization of the SAA is crucial for understanding core dynamics, geodynamo, and addressing societal issues. Research indicates that the SAA area and center exhibit time dependency, including periods of stability, eastward drift, and rapid southward drift.

Solar-cycle Variations of South Atlantic Anomaly Proton Intensities Measured with the PAMELA Mission

A. Bruno et al.

Summary: The study examined solar-cycle variations of >80 MeV proton flux intensities in the lower edge of the inner radiation belt using data from the PAMELA mission. The analyzed data covered an approximately 8-year interval and explored intensity temporal variations as a function of drift shell and proton energy, offering important constraints for modeling the low-altitude particle radiation environment at the highest trapping energies.

Observations and Simulations of Dropout Events and Flux Decays in October 2013: Comparing MEO Equatorial With LEO Polar Orbit

Viviane Pierrard et al.

Summary: Comparing ESA PROBA-V and NASA Van Allen Probes observations of electron flux in October 2013, we found that dropouts occurred in all energy bands during storms, and equatorially trapped electron flux was higher than at LEO. The outer radiation belt showed isotropic structure during quiet times and exhibited pitch angle dependence of high energy injection. The Dst effect during geomagnetic storms explained the characteristics of outer radiation belt electron dropouts.

Inner radiation belt simulations of the proton flux response in the South Atlantic Anomaly during the Geomagnetic Storm of 15 May 2005

Kirolosse M. Girgis et al.

Summary: A test particle simulation code was developed to simulate the inner proton belt response during a geomagnetic storm. The study focused on investigating proton flux variations in the South Atlantic Anomaly region with respect to space weather conditions. Results showed that proton flux decreased in the anomaly region during the main phase of the storm, but increased during the initial and recovery phases.
