Evaporation Station: Laser to Monitor Farm Water Use
LOS ANGELES — Drop by vaporous drop, the amount of water farmers lose through evaporation can be significant. But a scientist and his students intend to measure this amount exactly, using a telescope-like laser called a large aperture scintillometer to monitor the losses.
Jan Kleissl and his students from the University of California-San Diego believe that determining when and how fast water turns to air may help farmers maximize production during a time of drought — when regulations restrict the volume of water available to California farmers.
