Signatures of neutral gas gravity waves at high latitudes - EISCAT-radar ray simulations
Abstract
The present state of development of GIFTS (Graz Ionospheric Flux Tube Simulation), a numerical simulation model for the ionosphere at middle and high latitudes, is reviewed, and the first results of one-to-one comparisons between GIFTS model data and genuine EISCAT Common Program data are presented. First results are also reported on simulations of ionospheric signatures caused by the passage of neutral atmospheric gravity waves. The role of electric fields in the wave background is examined, and likely future applications of the GIFTS model are considered.
