The Tropospheric Doppler Radar Wind Profiler (TDRWP), located at Kennedy Space Center, is the only instrument of its kind in operation. Consisting of 640 antennae and occupying five acres near the Launch and Landing Facility, the TDRWP operates at nearly 50 MHz. It will be used as a primary instrument to measure upper level winds for NASA’s Artemis missions, which will launch from the Florida spaceport. The instrument has the ability to provide data from 6,000 to 62,000 feet, every five minutes, far outpacing weather balloons.
