Abstract VHF band stratosphere/troposphere (ST) radars around the globe are seldom operated in range-imaging mode. As such, the typical range resolution of their backscatter images is about 150 m. The only exception is the Kyoto University’s Middle

Abstract The standard model (e.g., Hocking in Earth Planets Space 51:525–541, 1999), $$\varepsilon = c_{0} \sigma^{2} N$$ ε=c0σ2N , (where $$\sigma$$ σ is the radar spectral width assumed to be equal to vertical turbulence velocity fluctuation $

Abstract We tested models commonly used for estimating turbulence kinetic energy dissipation rates $$\varepsilon$$ ε from very high frequency stratosphere–troposphere radar data. These models relate the root-mean-square value $$\sigma$$ σ of radi

Abstract On June 11, 2015, a train of large-amplitude Kelvin–Helmholtz (KH) billows was monitored by the Middle and Upper Atmosphere (MU) radar (Shigaraki MU Observatory, Japan) at the altitude of ~ 6.5 km. Four to five KH billows in formation and

Abstract The ShUREX (Shigaraki UAV Radar Experiment) 2015 campaign carried out at the Shigaraki Middle and Upper atmosphere (MU) observatory (Japan) in June 2015 provided a unique opportunity to compare vertical profiles of atmospheric parameters est

Abstract The Shigaraki unmanned aerial vehicle (UAV)-Radar Experiment (ShUREX) is an international (USA-Japan-France) observational campaign, whose overarching goal is to demonstrate the utility of small, lightweight, inexpensive, autonomous UAVs in

The WPR-LQ-7 is a UHF (1.3575 GHz) wind profiler radar used for routine measurements of the lower troposphere at Shigaraki Middle and Upper (MU) observatory (34.85° N, 136.10° E, Japan) at a vertical resolution of 100 m and a time resolution of 10
