Challenging JSBACH using tower data


The research focus of this thesis is on the evaluation of JSBACH by constraining this model with observations. Here, first data from the CASES-99 field experiment in Kansas will be used. The model will be run using the observed atmospheric forcing data at a reference height and the resultant surface fluxes of heat and moisture will be compared to observations to provide an assessment of the model's capacity to correctly reproduce the coupling between the land and the atmosphere throughout the diurnal cycle, in particular during the night where stable conditions prevail. In the second step, we will include a boundary layer representation in the model setup and compare modelled atmospheric profiles of temperature, humidity and wind with measurements. Data from the Hamburg Wettermast will be used as a reference. The scientific goal is to identify the most important land-atmosphere feedbacks in the coupled system operating on diurnal time scales.
