“…In this ÿgure, another density peak at 78 km in ascent is apparent. Such a 10-km vertical structure is also seen in the electron density proÿles both in ascent and descent (see Iwagami et al, 2002). Electron density peaks were found at 92, 102 and 112 km nearly in-phase with the O density proÿle.…”

“…The WAVE2000 campaign was carried out over Kagoshima, Japan, in January 2000. This campaign was planned to study the formation process of wave structures in the airglow image from both dynamical and chemical perspectives [ Iwagami et al , 2002, 2003]. The second campaign, WAVE2004, was conducted at the same place, Kagoshima, in January 2004.…”

[1] In order to investigate the dynamics of the mesopause region, foil chaff experiments were carried out successfully during the WAVE2000 and WAVE2004 campaigns at Kagoshima, Japan. In the WAVE2004 campaign, the height profiles of the horizontal and vertical wind speeds were obtained. The wind shear layers of >40 m/s/km were located around the altitudes of 89 and 95 km, and the profile of the Richardson number reveals the existence of dynamically unstable layers at about the same height region. Ripple observations using the all-sky imagers also support the possibility of dynamical instabilities. In the WAVE2000 campaign, a prominent small-scale feature around an altitude of 90.5 km appeared in both the horizontal and vertical chaff motions. These results demonstrate that the foil chaff technique is a valuable tool for in situ observation of small-scale turbulence features around the mesopause.

“…The altitude of the OH* layer has frequently been measured using rocket-borne photometers, satellite-borne instruments and lidar remote sensing (through calculating equivalent OH*-temperatures from lidar temperature profiles) and was always found to peak at that altitude region with some minor variability (e.g. von Savigny et al, 2004;Shepherd et al, 2004;Iwagami et al, 2002;Melo et al, 2000;She and Lowe, 1998;Takahashi et al, 1996;Mende et al, 1993;Takano et al, 1990;Baker and Stair, 1988;von Zahn et al, 1987;Lopez-Moreno et al, 1987;Watanabe et al, 1981;Witt et al, 1979;Good, 1976). We therefore assume that these values apply also to our measurements.…”
