Equatorial Atmosphere Radar (EAR)
Observation Data (Old type of NetCDF Data)


(Fitting Version 02.0212)

Please note: If you acquire EAR data, we ask that you acknowledge us in your use of the data. This may be done by including text such as EAR data provided by Research Institute for Sustainable Humanosphere of Kyoto University. We would also appreciate receiving a copy of the relevant publications. Thank you!
Old type of NetCDF (Network Common Data From) data is available below. File names are composed of date: (year)(month)(day).nc In the old type of NetCDF data, height range (1.05--23.4 km) and height interval of data were different from CSV formatted data.
In new NetCDF data , these are consistent with CSV formatted data, and the information for the number of averaging data is also included. If you need new NetCDF data. please refer here.
