Projekt Ecotech

MeteoEcoTech (MET)

Changes in climate and land use interact in a complex system with various feedbacks influencing water, carbon, and nitrogen fluxes. An objective of the MeteoEcoTech (MET) project is the detection and evaluation of effects of climate and land use changes on these fluxes and their contribution to site- and field-scale matter budgets.
Therefore, continuous measurements of energy and matter fluxes are carried out above different agricultural crops (2009 winter barley, 2010 rapeseed) at the cropland site Klingenberg.
The atmospheric boundary layer model HIRVAC (High Resolution Vegetation Atmosphere Coupler) will be used to simulate the recent and future conditions for energy and CO2 fluxes. Improved modules for nitrogen fluxes will be integrated. Thus, feedbacks between land-use, climate, energy, CO2, and nitrogen fluxes can be analysed. 
Furthermore, a data bank is created including data of flux measurements for all Tharandt cluster sites (spruce site Anchor Station Tharandt, grassland site Grillenburg, and the cropland site Klingenberg). The sites are within or nearby the Tharandt Forest. These datasets will be analysed for their representativeness in space and time.
The findings made in this project will account for evaluation of fluxes and trace gases between land surface and atmosphere. As a result, a set of parameters of different types of land use in this area will also be given.
