Micrometeorology Within and Above an Orchard Canopy: Measurements and Numerical Lattice-Boltzmann (LB) Studies

Understanding canopy micrometeorology is important for many environmental applications such as local/urban climate forecasting and exchange of material with the atmosphere. In this talk a micrometeorological analysis is presented based on a detailed measurement along a 16m tower within and above a typical 3m-orchard canopy during three days. We compare our observations to other campaigns, such as The CHATS experiment. The canopy flow and thermodynamic profiles are studied in terms of the local atmospheric stability. Numerical Lattice Boltzmann simulations of the canopy-flow aiming to capture the effect of stability on the flow profile are discussed.
