Research

Research Topics, Overview of the research

• Research Topics

  1. Study of equatorial atmosphere/ionosphere with the Equatorial Atmosphere Radar
  2. Study of ionospheric irregularities
  3. Study of coupling process in the ionospheric E- and F-regions
  4. Study of atmospheric turbulence
  5. Development of atmospheric radar and its observation techniques
  6. Development of measurement by means of sounding rocket and satellite-ground beacon experiment

• Overview of the research

  I study the Earth's atmosphere and ionosphere by using variety of radars, i.e., the MU radar and the Equatorial Atmosphere Radar, sounding rocket, satellites, etc. I am interested in vertical coupling processes in the atmosphere from near-ground to the ionosphere. I am conducting development of radar or other remote sensing equipment, measurement techniques, deploy of observation network, and total analysis of data. I study atmosphere/ionosphere in the mid-latitude region near Japan, and also the low-latitude region like the southeast Asia and Africa. I join domestic and international collaborative study programs by the Institute of Sustainable Humanosphere (RISH).
