The Institute for Space-Earth Environment Research (ISEE) of Nagoya University operates the Optical Mesosphere Thermosphere Imagers (OMTIs) since 1997. The OMTIs consist of more than fifteen all-sky cooled-CCD imagers, five Fabry-Perot interferometers, three airglow temperature photometers, and three meridian-scanning photometers. These instruments are in automatic operation at various locations from high to equatorial latitudes in Canada, Russia, Norway, Finland, Japan, Thailand, Indonesia, Nigeria, and Australia. They measure two-dimensional airglow images in the mesopause region and in the thermosphere, wind and temperatures in the lower thermosphere, and airglow rotational temperatures in the mesopause region. Recently we also started to deploy OMTI airglow imagers as well as 64-Hz induction magnetometers, 40-kHz VLF receivers, and 64-Hz riometers at 8 stations at magnetic latitudes of ~60 degree around the north pole to cover longitudinal variation of aurora and electromagnetic disturbances in the inner magnetosphere under the PWING project (study of dynamical variation of Particles and Waves in the INner magnetosphere using Ground-based network observations, http://www.isee.nagoya-u.ac.jp/dimr/PWING/PWING_web_e.htm), which will last for 5 years from April 2016, as a Grant-in-Aid for Specially Promoted Research of the Japan Society for the Promotion of Science (JSPS). In the presentation, we introduce current status and some recent results obtained by these multi-instrument ground networks around the world.
