TWP8 Wind Profiler radar is the
state-of-the-art meteorological equipment providing an
unattended UHF Doppler radar and RASS (Radar-Acoustic
Sounding System) that automatically and continuously
profiles the upper winds and atmospheric temperature.
TWP8 benefits
from the proprietary technology of Lockheed Martin
Corporation of the United States who is the source of the
Wind and Temperature Profiler system for American NOAA. The
characteristics of TWP8 is:
