Data (Ver2.0)

Data version 2.0 is released on July 7. In version 2.0, spectral width and doppler velocity are corrected in CSV and netCDF data, and variables indicating observation parameters (ipp, ndata, nfft, ncoh and nicoh) are added in netCDF data. Old version (version 1.0) is here .

Please note: If you acquire EAR data, we ask that you acknowledge us in your use o f the data. This may be done by including text such as EAR data provided by Research Insti tute for Sustainable Humanosphere of Kyoto University. We would also appreciate receiving a copy of the relevant publications. Thank you!
