Manastash Ridge Radar, Radar observatory in Ellensburg, United States
Manastash Ridge Radar is a passive radar observatory in the eastern Cascade Mountains near Ellensburg that detects ionospheric activity and meteor trails using commercial FM broadcasts. The system works by analyzing signals already present in the atmosphere rather than transmitting its own radar beams.
The University of Washington established this facility in 1972 as part of the existing Manastash Ridge Observatory for atmospheric research. The project emerged from academic interest in studying ionospheric behavior in mountainous terrain.
The facility demonstrates the intersection of academic research and practical meteorology, contributing to regional weather forecasting and aviation safety protocols.
The facility sits in a mountain area with restricted access requiring prior authorization from the University of Washington. Visitors should know this is an active research site not designed for casual public visits.
The facility receives data at two separate locations simultaneously: one at the University of Washington campus and another at Manastash Ridge itself, allowing synchronized measurements. This spatial separation of receivers is unusual and enables more precise understanding of atmospheric events.
