PSMOS/JAPAN Campaign observation '99/'00
Radio Atmospheric Science Center, Kyoto University
This page shows the radar and optical observation
of the mesopause region in November 1999 and January 2000,
using the instruments of Japanese PSMOS(Planetary Scale Mesopause
Observing System) group.
Campaign 1: November 8 -- November 19, 1999
(PSMOS with Leonids campaign)
Campaign 2: January 7 -- January 17, 2000
(PSMOS with Airglow Rocket campaign)
QUICKLOOK of the observational data
What to observe?
Atmospheric dynamics around the mesopause
Atmospheric waves such as gravity waves, tides, and planetary
waves, and their interactions, propagations will be studied
by the coordinated radar and optical measurements.
Leonid meteor activity
The forthcoming outburst of the leonid meteor stream
will be monitored with the MU radar, the most sensitive "meteor radar"
in the world to detect ionized meteor trails.
The same observation parameter has been used
from 1990 every year for leonids. A new technique to observe
meteor head echo will also applied during the observation this year.
Effects of the severe meteor outburst on the atmosphere
If there should be a severe meteor storm such as observed 32
years ago in USA, a significant amount of meteoriods would be
scattered around the mesopause. Variations of the atmosphere,
especially the minor consituents are monitored with active
and passive optical remote sensing.

Continuous operation (radar)
MF radars are operated continuously at these sites by CRL
(Communications Res. Lab.:K.Igarashi), which observes winds at 70-100km.
Ionosodes are also continuously operated at these sites.
Uchinoura and surroundings
Special campaign in January 2000 around Rocket launch
2 All-sky imagers of CRL (Kubota)
1 All-sky imager and 1 wideview imager of Tohoku U. (Fukunishi et al.)
These imagers are used to carry out triangulation of airglow height.
