Boundary Layer Radar (BLR) / Lower Troposphere Radar (LTR) / LQ7
Observation Data


(Version 02.0212)


Please note: If you acquire Shigaraki-BLR/LTR data, we ask that you acknowledge us in your use of the data. This may be done by including text such as Shigaraki-BLR/LTR/LQ7 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.


Archive parameters:
CSV (Comma Separated Values) formatted data are available.
File names of CSV data are composed of date and variable abbreviations: (year)(month)(day).(variable).csv
Latest ASCII data is also available.
