Hydroxyl response in the lower polar stratosphere during the 2005 Jan 20 Ground Level Enhancement Astronomical Society of Australia Annual Science Meeting 2010, Hobart, 5-8 July, 2010 (Ref: 14167)
Category 3: Poster

We evaluate atmospheric ionization during the Ground Level Enhancement (GLE) of 2005 Jan 20 using the continuous slowing down (CSD) energy loss approximation [1,2]. The top-of-atmosphere particle flux is derived using satellite measurements (for particle energies below 500MeV)…

Effects of atmospheric ionization during the ground level enhancement of 2005 Jan 20 6th Annual Meeting, Asia Oceania Geosciences Society, Singapore, 11-15 August 2009, 2009 (Ref: 14077)
Category 3: Abstract

We evaluate atmospheric ionization during the Ground Level Enhancement (GLE) of 2005 Jan 20 using two methods: a Monte-Carlo (MC) air-shower simulation [1] and a continuous slowing down (CSD) energy loss approximation [2,3]. For both methods…

Atmospheric chemistry effects of the 20 January 2005 solar proton event Advances in Geosciences, 2009 (Ref: 13962)
Category 1: Peer-reviewed literature

Atmospheric ionization during Solar Proton Events (SPE) has traditionally … been modeled using top-of-atmosphere (TOA) particle fluxes measured by near- … Earth spacecraft, and as a consequence the modeling has been restricted to … particle energies below ¡­ 500 MeV. However…
