These were; ozone density measurements, by both National Institute for Environment Studies and Meteorological Research Institute, sodium layer measurements by Shinshu University, atmospheric turbulence, wind direction and speeds using MU radar by Kyoto University, ionosphere monitoring such as of fmin by Communication Research Laboratory from five ionosondes located in Japan, and finally rocket launchings carried out by two institutions, Japan Meteorological Agency and Institute of Space & Astronautical Science.
