QS_II | ARTEMIS: Improving the spatio-temporal variability of Analysed and near Real-Time greenhouse gas EMISsions for North-Western Europe
The ARTEMIS project associated with ITMS, which is being carried out by the FU Berlin, aims to improve the understanding of the processes and mechanisms that cause the spatio-temporal variability of anthropogenic greenhouse gas emissions. At the same time, a modelling approach is being developed that provides high-resolution emission information for the ICON-ART model used by DWD for ITMS. ARTEMIS co-operates closely with the work package QS_I WP1 (UBA) to improve the spatial and temporal distribution of emissions from the National Inventory Report.
Although the exploitation of modern observation systems for greenhouse gas concentrations and fluxes requires temporal explicit modeling, the accurate representation of the spatial and temporal variability for important emission sectors is still largely absent in the a-priori information on anthropogenic emissions. The latter mostly provide annual maps with sector-dependent static time profiles in order to take intra-annual fluctuations into account.The main objective is to develop spatially (2x2 km2) and temporally (hourly) highly resolved GHG emission data. For this purpose, we will adapt a spatio-temporal dynamic emission model under development for air pollutants to account for the greenhouse gasses carbon dioxide (CO2) and methane (CH4). The targeted developments aim to develop the parametrizations for anthropogenic emissions by combining activity modeling in a data driven manner and emission behavior modeling including dependence on environmental conditions. We especially aim to include emission variability that will cause systematic differences in modeled intra-annual GHG concentration variability and thus the source receptor relations. Finally, we will expand the emission inventory with information on isotopic composition to allow for evaluation against the newest ICOS observations. The dynamic emission model delivers 4D data, for which an interface to the ICON-LAM-ART will be developed early in the project to ensure correct uptake of the data stream.
The dynamic emission model provides 4D data and to ensure the efficient incorporation of this data into the ICON-ART model, the existing emission interface will be extended to read and process the 4D emission data stream. The model will then be used to quantify the added value of the improved emissions information compared to ICOS observations.
The project is being carried out in close co-operation with the UBA, DWD, KIT and other ITMS partners, but also with external partners such as TNO and EMPA. The provision of the novel a-priori information will enable ITMS to perform emission verification simulations at national level with unprecedented resolution. In collaboration with the ITMS consortium, the understanding of the national contribution to emissions and concentration variations observed by in-situ and remote sensing platforms will be improved.
