| 観測機器 | Near InfraRed Aurora and airglow Camera (NIRAC): This camera consists of a few commercial SWIR lenses that are typically used for security/defense purposes, plano-convex lenses, a custom optical filter (center: 1113 nm, FWHM: 13.8 nm) and a 2-D InGaAs FPA. Total optical system is fast (F-number 1.5) and its field-of-view (84° x 68°) is slightly wider than the meridional coverage of the NIRAS-2. The NIRAC can visualize two-dimensional structures of not only aurora but also even weak OH airglow with a cadence of less than 30 seconds. | ||

| データポリシー | Please contact the Principal Investigator of this project (nishiyama.takanori [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: 'Aurora image data was provided by National Institute of Polar Research, Japan. This observation at Longyearbyen, Svalbard was supported by the Japan Society for the Promotion of Science (JSPS), Grants-in-Aid for Young Scientists (A) 17H04857, Scientific Research (B) 20H01955, (B) 20H01962, (B) 21H01144, and (B) 24K00697. This was also supported by the joint research program of Planetary Plasma and Atmospheric Research Center, Tohoku University, the joint research program of the Institute for Space-Earth Environmental Research, Nagoya University and the Project Research KP301 of the National Institute of Polar Research.' |
