The Lexan Rain Gauge Wind Screen minimizes the formation of strong updrafts that can distort the trajectories of precipitation particles falling toward a gauge. The screen also generates turbulent air motions over the gauge orifice to break up streamlines and thus improve the catch. Use of a wind screen is recommended with all precipitation gauges located in windy areas. The screen consists of 32 free swinging leaves, evenly spaced around a 48 in. diameter ring. Each leaf is fabricated from GE LEXANTM , a space-age material resistant to weather and solar radiation. The legs are 24 inches long.
