My specialist areas are in boundary layer meterology; land-surface-atmosphere interactions; footprint modelling; greenhouse gas fluxes. My research focuses on interactions of the terrestrial biosphere and the lower atmosphere. This includes:
- Footprint/source-area modelling based on a backward Lagrangian particle dispersion model to determine the upwind surface area of influence for an atmospheric flux or concentration measurement.
Online footprint estimate: Calculate a footprint using a simple parameterisation.
footprint.kljun.net - Vegetation – atmosphere carbon and water vapour exchange: processes controlling and influencing the carbon and water balances.
- Upscaling of local greenhouse gas flux measurements to a regional or continental scale, taking into account heterogeneous surfaces, complex terrain, and issues in spatial and temporal resolution.
