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. The PWING project (study of dynamical variation of Particles and Waves in the INner magnetosphere using Ground-based network observations, 2016-2022) 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. Although the PWING project of JSPS Kakenhi budget officially ended on March 2023, 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. From January 2023, a new project “International joint research of geospace variability by combining multi-point ground and satellite observations and modeling (PBASE program)” has been started (https://www.isee.nagoya-u.ac.jp/dimr/PBASE/index-e.html). This program encourages combining these ground-based observations with satellite observations and modeling through supporting students and early-career scientists. In the presentation, we introduce current configuration and recent results in 2022-2023 obtained by these multi-instrument ground networks, and introduce the new PBASE program.
