[PEM12-08] サブオーロラ帯から赤道域をつなげるPWINGプロジェクトと超高層大気イメージングシステムの地上多点観測網の現状
キーワード：夜間大気光、オーロラ、電離圏
The PWING project (study of dynamical variation of Particles and Waves in the INner magnetosphere using Ground-based network observations, 2016-2020) operates all-sky airglow/aurora imagers, 64-Hz sampled induction magnetometers, 40-kHz VLF receivers, and 64-Hz riometers at 8 stations at magnetic latitudes of ~60 degree around the north-pole. The PWING stations cover longitudinal variation of aurora and electromagnetic disturbances in the inner magnetosphere. The Optical Mesosphere Thermosphere Imagers (OMTIs) consist of more than 20 all-sky cooled-CCD imagers, 5 Fabry-Perot interferometers, 3 airglow temperature photometers, and 3 meridian-scanning photometers. The OMTIs measure two-dimensional airglow images in the mesopause region and the thermosphere, wind and temperatures in the lower thermosphere, and airglow rotational temperatures in the mesopause region. These PWING and OMTIs instruments are in automatic operation at various locations from high to equatorial latitudes in Canada, US (Alaska), Russia, Norway, Finland, Iceland, Japan, Thailand, Indonesia, and Australia. We also recently develop low-cost cameras to expand the network to connect between subauroral latitudes and equatorial latitudes. In the presentation, we introduce current configuration and recent results in 2021-2022 obtained by these multi-instrument ground networks.
