Paper Abstract

Laboratory measurements of microscopic level changes in a water tank were shown to have good correlation with the evaporation rate predicted using Dalton's Law. Submicron level changes in the tank were measured in real-time using an interferometer interfaced to a PC. The methodology developed offers a way to build an instrument that can be used as a standard for an evaporimeter or a hygrometer. The real-time measurement capability provides a tool for determining refined dynamic correlations of evaporation with fast changes in meteorological variables such as wind and solar radiation.
