STATISTICAL PROPERTIES OF AURORAL KILOMETER RADIATION: BASED ON ERG (ARASE) SATELLITE DATA
Journal Title: Solar-Terrestrial Physics - Year 2021, Vol 7, Issue 1
Abstract
In this work, we have studied the signals of auroral kilometer radiation (AKR) from sources in the auroral regions of the Northern and Southern hemispheres simultaneously recorded by one satellite. We have carried out a detailed statistical analysis of more than 20 months of continuous AKR measurements made by the ERG satellite (also known as Arase). This made it possible to confirm the previously obtained results on the location of AKR sources and seasonal changes in the radiation intensity. Open questions about the processes in the AKR source can be solved using data on the radiation pattern under various geomagnetic conditions. To answer these questions, we have estimated the cone angle of directional diagrams in the dusk and dawn sectors of Earth’s magnetosphere.
