Airports with a TDWR in the US. Another in San Juan, Puerto Rico, is not shown on this map.. Terminal Doppler Weather Radar (TDWR) is a Doppler weather radar system with a three-dimensional "pencil beam" used primarily for the detection of hazardous wind shear conditions, precipitation, and winds aloft on and near major airports situated in climates with great exposure to thunderstorms in the ...
Windshear deployment studies conducted from 1989 through 1994 determined at which LLWAS-II sites weather exposure justified upgrade to a weather radar (Terminal Doppler Weather Radar (TDWR) or Weather Systems Processor (WSP)) an LLWAS Network Expansion (LLWAS-NE) or LLWAS-Relocate/Sustain (LLWAS-RS) upgrade, singly or in combination. By 2005 ...
