Abstract: The foil chaff technique is a simple in-situ technique to measure neutral winds in the mesopause region. In order to conduct foil chaff experiments by sounding rockets, two types of foil chaff ejection systems have been developed in Japan. The high resolution in altitude of the obtained neutral wind data by the foil chaff technique provides useful information for various studies on the dynamics in the mesopause region, when combined with simultaneous measurements of other geophysical parameters.
Key words: Neutral wind, mesosphere and lower thermosphere, foil chaff technique, sounding rocket.
