Middle and Upper atmosphere (MU) Radar
Observation Data

(Fitting Version 01.0807 and Data Vesion 1.02)

Updated: Data version 1.02 were released (July 4, 2013). Old version (Ver. 1.01 is here)
Please note: If you acquire MU radar data, we ask that you acknowledge us in your use of the data. This may be done by including text such as MU radar data provided by Research Institute for Sustainable Humanosphere of Kyoto University. We would also appreciate receiving a copy of the relevant publications. Thank you!
This data has been registered in IUGONET (Inter-university Upper atmosphere Global Observation NETwork) metadata database. The IUGONET metadata database will be of great help to researchers in efficiently finding and obtaining ground-based observation data spread over the institutes/universities. Click and visit to the IUGONET website.

IUGONET also prepared the iUgonet Data Analysis Software (UDAS) for the upper atmospheric observation data. If you install the UDAS, you can easily access, download, visualize and analyze the MU radar observation data through the Internet. Please click and try to use the UDAS.
