Changes of the aerodynamic characteristics of a flux site after an extensive windthrow

Bruna R. F. Oliveira, Jan J. Keizer, and Thomas Foken

Data sets

Daily Carbon Dioxide fluxes measured by an eddy-covariance station in a recently burnt Mediterranean pine stand in Central Portugal B. R. F. Oliveira, J. J. Keizer, and T. Foken https://doi.org/10.1594/PANGAEA.921281

Model code and software

Eddy-Covariance software TK3 M. Mauder and T. Foken https://doi.org/10.5281/zenodo.20349

Short summary

This study analyzes the impacts of this windthrow on the aerodynamic characteristics of zero-plane displacement and roughness length and, ultimately, their implications for the turbulent fluxes. The turbulent fluxes were only affected to a minor degree by the windthrow, but the footprint area of the flux tower changed markedly so that the target area of the measurements had to be redetermined.
