TDWR - Terminal Doppler Weather Radar, 1985-1993, undated

Terminal Doppler Weather Radar -- convective weather research and prototype development at NCAR in the 1980s and 1990s strongly influenced the design, scanning strategies and end–user products generated by this aviation–weather radar system that was installed at 50 major airports in the US. NCAR also holds the patent for algorithms integrating TDWR and LLWAS data. NCAR's prototype TDWR system was successfully used to protect Denver's Stapleton Airport from wind shear for six years until the operational TDWR took its place at Denver International Airport.
