This report describes the development, testing, and use of a three-cup type anemometer, the cup-wheel assembly of which is constructed of “ping-pong” balls. The anemometer has certain superior qualities with respect to ease of construction, ease of recording, low starting speed, and rapid response. With certain simple modifications it should be considered as a general purpose micrometeorological research tool.
