Project: Study of coupling in the atmosphere-ionosphere system evoked by short-period atmospheric waves

The main objective of the project, to study the impact of 
gravity and infrasonic waves coming from below lying neutral 
atmosphere (mainly troposphere) on the upper atmosphere-ionosphere 
system, is divided into several tasks as follows:
(1) To install our Doppler system of several measuring paths in 
Taiwan and validate its measurements.
(2) Comparison of Doppler system measurements and derived waves at 
various locations worldwide (our system measurements in Czechia, 
South Africa and Argentina).
(3) The relation between typhoons and gravity and infrasonic waves in 
the ionosphere. Taiwan is an ideal place for such a study.
(4) The relation of the ionospheric phenomenon spread-F to gravity 
and infrasonic waves. The expected remarkably higher level of wave 
activity above Taiwan creates much better conditions for such a 
study. 
(5) What is the response of Doppler system measurements during 
ionospheric scintillation events?
