| Description | Cosmic Noise Absorption (CNA) measured at 1-sec intervals with the 38.2MHz imaging riometer (IRIO) at Syowa Station, Antarctica. The data recorded during the period from 2016 are available. The imaging riometer observes the ionospheric absorption of cosmic radio noise caused by auroral electron precipitation. The 8x8 CNA data are obtained in the horizontal area of 200km x 200km at 90km altitude every second. |

| Terms of Use | Please contact the Principal Investigator of this project (uapdata [at] nipr.ac.jp) before using the data at any publications and/or presentations. We welcome collaborative research and strongly recommend users to contact us early in order to ensure that the data are suitable for their research. When the data are used at any publications and/or presentations, we would like to ask the users to acknowledge NIPR and send us the PDF files of the publications and/or presentations. An example of the acknowledgement statement is as follows: "Imaging Riometer data were provided by National Institute of Polar Research, Japan. The Upper Atmosphere Physics Monitoring Observation at Syowa Station was mainly supported by the Research Program of Japanese Antarctic Research Expedition (JARE) of the Ministry of Education, Culture, Sports, Science, and Technology of Japan (MEXT). The distribution of the magnetic field data has been partly supported by the IUGONET (Inter-university Upper atmosphere Global Observation NETwork) project (http://www.iugonet.org/) funded by the MEXT." |
