The Super Dual Auroral Radar Network (SuperDARN) is a powerful tool for monitoring ionospheric plasma convection and electron density changes in the high- and mid-latitude ionosphere. At present, a total of more than 35 SuperDARN radars in both hemispheres cover the geomagnetic latitude range of about 40 to 90 degrees, yielding many scientific results on a wide variety of scientific topics related to the dynamics of the ionosphere, which is affected both by the disturbances from above (magnetosphere), and those from below (thermosphere, atmosphere and even the ground/sea surface perturbations). In particular, mid-latitude SuperDARN radars, including two radars located in Hokkaido and operated by ISEE, Nagoya University, have been demonstrating the capabilities of the mid-latitude SuperDARN in various aspects. This paper will present an overview of the latest achievements, recent progress, and future plans (both short- and long-span) of the mid-latitude SuperDARN network.
