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

November 1999 campaign (Leonids campaign)


January 2000 campaign (Rocket campaign)



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.

Observational Plan
