The main purpose of this installation is to offset the vertical fall speed of cloud and precipitation particles with a low-turbulence, variable-speed, upward-moving column of air in which the temperature, moisture, and electrical environment can be controlled in a selected observable region of laboratory space. The Vertical Wind Tunnel can be used for study and calibration of cloud physics instruments. Show less
