A new JSPS Kakenhi program “International joint research of geospace variability by combining multi-point ground and satellite observations and modeling (PBASE program)” has been started since January 2023. This program encourages international collaborative studies of combining ground-based and satellite observations of geospace with modeling through supporting students and early-career scientists. The ground-based network observations are originally based on the PWING project (study of dynamical variation of Particles and Waves in the INner magnetosphere using Ground-based network observations, 2016-2022) which 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, in order to cover longitudinal variation of aurora, airglow, and electromagnetic disturbances in the inner magnetosphere. These aurora/airglow imagers are part of the Optical Mesosphere Thermosphere Imagers (OMTIs). 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. In the presentation, we show current configuration of these ground-based network observations and provide updates of the ground-satellite-modeling coordination under the PBASE program.
