A wind profiler is a type of weather observing equipment that uses radar or sound waves (SODAR) to detect the wind speed and direction at various elevations above the ground. Readings are made at each kilometer above sea level, up to the extent of the troposphere (i.e., between 8 and 17 km above mean sea level). Above this level there is inadequate water vapor present to produce a radar "bounce." The data synthesized from wind direction and speed is very useful to meteorological forecasting and timely reporting for flight planning. A twelve hour history of data is available through NOAA websites.

Famous quotes containing the word wind:
“The wind and the rain, gives this place a gleam that just isn’t natural. And the ground, alive with crawling things, crawling death.”
—Edward D. Wood, Jr. (1922–1978)
