Modeling the Influences of Acoustic Gravity Waves Due to Seismic Events and Atmospheric Sources on the Low- to Mid-Latitude Ionosphere

Abstract

LONG-TERM GOALS. The goals of our research within the ONR BRC program were to advance the understanding of, and predictive capabilities for, forcing of the ionosphere accompanying acoustic-gravity waves arising due to terrestrial and atmospheric sources. OBJECTIVES. Our four-year research program was a collaborative effort between GATS, which employs afinite-volume (FV) code to describe the nonlinear dynamics of acoustic-gravity waves (AGWs) in a deep atmosphere, and the Naval Research Lab. (NRL), which developed the SAMI3/ESF model of the ionosphere. Employing the FV code results as inputs to the SAMI3/ESF globalionosphere model enabled us to jointly address ionospheric responses to various anticipated AGW sources, parameters, and spatial distributions.
