| Title: | Main Title: Cutting-edge Coupling Issues for Carbon Dioxide and Moisture Exchange in COSMOs Soil-Vegetation-Atmosphere Interaction |
| Description: | Abstract: The gas exchange between land surface and atmosphere is becoming an increasingly important component in modelling the status and the future of atmospheric processes. Soil moisture speci cation and carbon dioxide concentration exhibit feedback to these processes by strongly in uencing temperature and relative humidity. CO2 is not considered in COSMO, more precisely not in its land surface parameterization (LSP) scheme TERRA. Hence, the so-called A-gs model will be included into TERRA. The soil moisture in COSMO is initialized by a data assimilation approach called SMA (soil moisture analysis) that uses estimated error variances and covariances. This method is replaced with applying the neighborhood method to model data from several time-levels. We expect, that the new model version COSMO-TERRA-Ags with improved soil moisture initialization will show robustness and parameterizes moisture elds in space and time more accurate. This will show how strong CO2-fluxes in uence the water vapor release by plants and to which extent soil water modi es the water content in the plants and, thus, the atmosphere. |
