The measurements of surface energy and water vapor fluxes at large scale are crucial for solving the area-averaging problem from local in situ measurements to area-integrated information, validating hydrological and meteorological models, and verifying remote sensing products etc. This paper reviews the worldwide progress in surface energy and water vapor fluxes at large scale using scintillometer, from these aspects of observation instruments and experiments, and processing, analysis and application of observational  data. A  brief  outlook  about scintillometer is given.
