Title: Enhancing Geospace Observations with Autonomous Magnetometers in Antarctica: Global Context and Validation
Description: The extreme and remote environments of Antarctica present unique challenges and opportunities for geospace observations. Autonomous magnetometers, deployed across the continent, have become crucial tools in capturing high-resolution data critical for understanding Earth's magnetosphere and its interaction with the solar wind. This talk will discuss the role of these autonomous systems in enhancing global geospace observations, focusing on their deployment, operation, and the significance of continuous, long-term data collection in these isolated regions. We will also explore the global context of these observations, emphasizing their contribution to international research collaborations and space weather modeling. Key validation efforts, including data calibration, cross-referencing with other global networks, and recent case studies, will be presented to highlight the reliability and scientific impact of these autonomous systems. This work underscores the importance of innovative, low-power, and self-sustaining technologies in advancing our understanding of polar geospace environments and their broader implications for space weather research.
