Energy Flux and Conductance from All-Sky-Imagers
Abstract
As part of NASA's THEMIS mission, an array of all-sky-imagers (ASIs) across Canada monitors the majority of the nightside auroral oval at a three second cadence, providing a global view at temporal & spatial resolutions required to study the aurora on meso-scales. Increased computational abilities now also allow modelers to simulate the effects of auroral precipitation on these smaller spatial scales (10s-100s km) & faster timescales (seconds), including ionospheric conductivity, making it more important than ever to provide data to compare and contrast. We present a two-dimensional product of energy flux and conductance for several events, utilizing THEMIS ASIs to determine energy flux and characteristic energy in conjunction with the Boltzman Three Constituent (B3C) auroral transport code to determine conductance. We compare values with PFISR observed results and find a good comparison.
