Measurement of the Vertical Water Vapor Flux in the Convective Boundary Layer Using a DIAL and a Coherent Wind Lidar

摘要

A ground-based vertically-pointing water vapor DIAL and a coherent wind lidar were used to determine the vertical flux of latent heat in a convective boundary layer by means of eddy correlation. Vertical profiles as well as the temporal evolution of the flux were derived from the data. Instrumental white noise and the sampling error represent the main error sources for this kind of measurement.
