Recently, a breakthrough has been achieved in the development of 3D scanning water-vapor, temperature, and wind lidar systems. Based on a novel combination of their operation modes, it is possible to determine profiles of these variables from the canopy top to the free troposphere with high spatial and temporal resolutions over different land cover. Furthermore, in vertical staring modes, mean and gradient profiles as well as profiles of higher-order moments and fluxes can be determined simultaneously. Therefore, in both the surface and the interfacial layers, flux-gradient-variance relationships can be investigated, which may provide the basis of advanced, scalable parameterizations of turbulence exchange and transport in complex terrain.
In this presentation, the first application of this synergy is presented, which took place within the scope of the Land Atmosphere Feedback Experiment (LAFE) conducted at the ARM SPG site during August 2017. First results are presented and discussed.
