| Session Description | Earth’s upper atmosphere, especially, the ionized component is sensitive to disturbance waves propagated from the lower altitudes. These waves are atmospheric acoustic and gravity waves (AGWs) that can be generated by lithosphere activities and lower atmosphere disturbances, such as seismic, tsunami, volcano eruptions, hurricane, tornados, and meteorological disturbances. The upward propagations of AGWs are affected by the environmental atmospheric conditions and thus various wave characteristics can be detected in the upper atmosphere parameters, like neutral temperature, neutral density, and electron density. Additionally, human activities also generate anthropogenic disturbances that will be observable in the upper atmosphere. In order to better understand the vertical coupling of the lithosphere-atmosphere-ionosphere, it is the objective of this session to solicit discussions on the upper atmospheric disturbances in both neutral and ionized components resulting from the disturbances of lower altitude origins. |
