A MONTE CARLO SIMULATION OF SOLAR X-RAY TRANSPORTION IN EARTH'S ATMOSPHERE
-
摘要: 应用MonteCarlo方法对太阳X射线暴(1-8Å及0.5-4Å)与地球大气相互作用过程进行跟踪模拟,得到了X射线暴在电离层D层产生的电子产生率,并计算了由此产生的宇宙噪声吸收值。结果与作者在南极观测得到的X射线暴期间宇宙噪声吸收值符合较好.

Abstract: The Monte Carlo method is applied to simulate solar X-ray bursts (1-8 Å, 0.5-4 Å) transportation in earth's atmosphere. And the electron production rate due to solar X-ray bursts penetrating in ionospheric D-layer is calculated. From that, we can get the value of cosmic noise absorption. Aexample result of solar X-ray bursts is compared with the value of Riometer absorption observed in antarctic Zhong-Shan station, showing very good correlation.-
