Characterizing Auroral‐Zone Absorption Based on Global Kp and Regional Geomagnetic Hourly Range Indices

Abstract Increased ionization in the auroral oval leads to the absorption of high‐frequency radio waves in the auroral zone, or auroral absorption. Auroral absorption is typically characterized by global geomagnetic activity indices, such as the Kp index. In this paper the hourly range of the magnet...
