Abstract
A network of over 10 relatively closely packed VHF windprofiler radars is under construction in Ontario and Quebec, Canada. Using frequencies in the range 40 to 55 MHz, this network is interlinked by the internet and provides bufr format to the Canadian Meteorological Services and other interested parties on an hourly basis. Radars are separated by typically 150 km. The system presents horizontal winds, vertical winds, turbulence estimates, tropopause height determination, and scatterer anisotropy characteristics, from 400m to typically 14 km altitude. Five systems are currently active, and others are due on-line in the next 2 years. Current capabilities and future plans will be discussed.
