Space Weather Radiation Impacts on Aviation
摘要
Measurements of radiation exposure within the African region are rare or non-existent and as such, different available models are utilised to evaluate the amount of radiation exposure at flight levels. This paper discusses the results computed using CARI7 model for selected periods 2–8 November 2021 and 8–13 May 2024. This is done for flight routes between Cape Town (CPT) (33.97° S, 18.60° E) and Johannesburg (JNB) (26.13° S, 28.24° E) in South Africa and between Johannesburg and Ethiopia (HAAB) (8.98° N, 38.803° E). The maximum computed effective dose for the CPT-JNB route during the period of 2- 8 November 2021 is ~ 5.9 μSv/h which was on the 4th of November 2021. However, during the period of 8–13 May 2024, the computed maximum effective dose is ~ 5.8 μSv/h and there was no distinction in the amount of dose computed for this period. On the other hand, the maximum computed effective dose for the JNB-HAAB route during the 2–8 November 2021 period is ~ 4.9 μSv/h which was on the 4th and for the period of 8–13 May 2024 the maximum computed dose is ~ 3.9 μSv/h for the entire storm period.
