Title(s):Main Title: Inclusion of CO2 fluxes in a coupled mesoscale land surface and atmospheric model
Description(s):Abstract: For mesoscale weather forecasting as well as for climate simulations with numerical models, a detailed knowledge of land surface characteristics and the exchange between the lower atmosphere and the land surface is needed. For that reason, in the project section C4 a fully coupled model system which comprehensively simulates atmosphere, vegetation and soil including their exchange processes related to water, CO2, heat and momentum will be developed. These fluxes are important because there are complex feedbacks between heat, water and carbon cycle on different temporal and spatial scales which influence weather and climate. My task deals with the inclusion of CO2 fluxes (i.e. soil respiration, soil storage, photosynthesis) in this coupled model system consisting of the atmospheric model COSMO (Consortium for Small-scale Modeling) and the land surface model CLM (Community Land Model). Firstly, carbon dioxide (CO2) will be included as a prognostic variable in the transport routines (advection, turbulence, diffusion, convection) in the COSMO model (see chapter 3). Afterwards, the lower boundary condition of the COSMO model at the interface between atmosphere and land surface must be developed to couple this CO2 tracer with the sources and sinks of CO2 in the vegetation scheme of CLM (see chapter 4). Including all interactions improves the simulation of the surface CO2 and the latent and sensible heat fluxes, which control the CO2 concentration in the planetary boundary layer.
