Description: A reliable assessment of future climate impacts in Austria makes necessary to provide regional climate model (RCM) runs, and additional tasks to deliver high resolution downscaled datasets for past and future climate targeting the entire eastern alps covering Austria. The project reclip:more (Research for Climate Protection: Model Run Evaluation) is a cooperation of five academic institutions. The major scientific goals are: quantify the uncertainties of regional climate simulations elated to observed climate data, investigate the sensitivity of regional climate simulations and interpolated climate data to the influence of different model parameters and data processing techniques, deliver regional climate change scenarios at mesoscale and microscale resolutions for the eastern Alps covering Austria . To achieve this, data preparations, a set of common model experiments and data evaluations have to be carried out with sensitivity studies. In project year 1 (Nov. 2003 to June 2004, postponed to Oktober 2004) the reclip:more-teams focused on preparative work for the 10-year simulations, using ERA-40 data and ECHAM5 control runs of current climate from the 1990ies. Furthermore a huge number of sensitivity studies aiming at finding the optimal RCM-setup (e.g. extent and position of the nests, nesting strategy, parameterization, etc.) were made. Additionally, different examinations concerning further statistical downscaling and on the preparation of validation data and methods were done. To compare the model results with observation data, monitoring data sets for Austria and synoptic data sets for entire Europe have been prepared. In the 2nd year (Nov. 2004 to June to Oktober 2005) the emphasis lay on the retrospective model runs with the two RCMs and the re-analysis/GCM-datasets for 1981-1990. Also a number of short episode runs and 7 annual runs with different settings were evaluated. At the end a comprehensive benchmarking of the model-outputs was done. At the same time the prospective model runs were prepared. The second main topic was the development of downscaling techniques for the regionalization of observation data and model results in the Alpine region. Downscaling of model results for a resolution of 1 km have been derived for temperature, precipitation and solar radiation with terrain-related response variables (for irradiation additionally with radiation-physics-related numerical functions). For near-surface-wind a method was accomplished by dynamical downscaling via MM5 and CALMET. In year 3 the prospective model runs for 2041-2050 will follow. With the in PJ2 developed techniques the model results will be downscaled to 1km for three study regions in Austria . At the end the transient high resolution results and monitoring data will be provided to the interested climate community.
