24 january 2024
Xing Meng, Olga P. Verkhoglyadova, Sandra C. Chapm...
Global ionospheric total electron content (TEC) maps exhibit TEC intensifications and depletions of various sizes and shapes. Characterizing key fe...
What does complexity science mean for Heliophysics? A living history and demonstrating a new paradigm in the study of GICs
UNDERSTANDING GEOMAGNETICALLY INDUCED CURRENTS AND THEIR IMPACT ON TECHNOLOGY II ORAL
spa-magnetospheric physics | 14 december 2023
Ryan M. McGranaghan, Lauren Orr, Sandra C. Chapman
Heliophysics processes span at least 15 orders of magnitude in space and another 15 in time, and its reaches go well beyond our own solar system and E...
