Ionospheric Response to Solar Flares Using an Improved Version of SAMI2
Abstract
Solar flare-induced disturbances in the ionosphere can affect the propagation of electromagnetic waves, causing errors in GPS navigation, false radar echoes, and loss of HF radio communications. Accurately modeling the ionospheric response to flares is the first step in predicting, and eventually mitigating their effects. Sami2 is Another Model of the Ionosphere (SAMI2) is a 2-D ionospheric model, which, in its standard form, is ill-suited for studying solar flare effects because it lacks adequate temporal resolution of the solar irradiance, and does not account for photoelectron effects. These deficiencies are addressed, and the modified version is successfully used to model the response to the 28 October, 2003 X17.2 solar flare, along a 2-D hemispheric domain. The response to the flare varied significantly between the low and mid-latitudes, and between high and low altitudes.
