Our group has developed a whole atmosphere-ionosphere model GAIA (Ground to topside model of Atmosphere and Ionosphere for Aeronomy). GAIA includes atmospheric regions from the ground surface to the upper thermosphere/ionosphere, so that GAIA can simulate excitations of atmospheric waves in the troposphere/stratosphere and their impacts on the variability in the thermosphere/ionosphere. Furthermore, GAIA can estimate variation in the minor constituent (such as NO, O3) in the thermosphere, which is caused by variation in the solar and geomagnetic activity, and its impact on the general circulation in the stratosphere/mesosphere. In this talk, we introduce recent results obtained by GAIA and future plans for GAIA development.
