Cosmic Radiation Dose‐Rates for Civil Aviation in the Middle East: Vertical Structure, Solar Modulation, and Comparison With Models

Abstract High‐altitude balloon measurements were conducted over southern Israel (30°35′N, 34°45′E; 850 m a.s.l., geomagnetic rigidity cutoff 10.3 GV) to characterize the vertical profiles of atmospheric ionization and radiation up to ∼35 km. Six balloon launches between October 2...
