- Biosphere-atmosphere exchange processes
- Energy-balance closure
- Large-eddy simulations
CHEESEHEAD is an acronym that stands for “Chequamegon Heterogeneous Ecosystem Energy-balance Study Enabled by a High-density Extensive Array of Detectors”.
The core of the project is an intensive field campaign covering a 10 by 10 km2 area in northern Wisconsin, USA. The overall goal is to investigate the influence of spatial heterogeneity on biosphere-atmosphere interactions within the atmospheric boundary layer. Understanding the impact of those processes on large-scale dynamics and improving scaling methods of surface fluxes is important for weather prediction and climate models where those surface fluxes are not resolved.
My contribution to CHEESEHEAD is the performance of large-eddy simulations to quantify and parametrize the effect of ecosystem heterogeneity on dispersive latent and sensible heat fluxes that cannot be captured by single-tower eddy-covariance measurements. The resulting underestimation of latent and sensible heat fluxes is one of the main causes of the energy balance closure problem.
