中高層大氣遙測技術的先期研究

Project Details

Description

The layer between 10 and 100 km altitude in the Earth atmosphere is generally categorized as the middle atmosphere. The boosting development of rocket and satellite technologies during the past 50 years has made it possible to probe the middle atmosphere directly. However, ground observation using optical remotesensing or scientific payload onboard CubeSat is a relatively economical and flexible way to explore the middle atmosphere's scientific topics. Now, we have developed the optical techniques and instruments to focus on the atmosphere electricity-related problems: (1) high-speed camera system up to 10,000 fps; (2) spectrograph for sprites, and (3) VLF/LF magnetic field ground station. We will study the effects of space charges and electric fields on the middle atmosphere for the theoretical model. We will develop the coupling model between the timevarying electrostatic model and an acoustic model. Using the coupling model, we can study the generated acoustic wave from the surface charge region and estimate their effect on the middle atmosphere. We will design the scientific payload of probing ionosphere using a airglow emission detector and investigate their application for instrument development. In this proposal, the electro-acoustic model will strengthen the research capability of atmosphere electricity, and designing the critical component of ionosphere probing will enhance our technology.
