Overall Aim of the Project investigate the influence of simultaneously observed wind and water

Overall Aim of the Project investigate the influence of simultaneously observed wind and water vapour fields from airborne lidar observations during COPS on the skill of the NWP, especially the quantitative precipitation forecasts using the 4 D-Var data assimilation scheme of the ECMWF-IFS In order to reach this goal, we proceed in three steps: 1. check of the data quality and coverage of the lidar data for the three UOPs with airborne observations during ETRe. C 2007, 2. analyse the wind and water vapor lidar data and perform a case study of a selected ETRe. C case, and 3. investigate the impact of the targeted airborne wind and water vapour observations and of the additional radiosonde and highfrequency AMDAR measurements of selected UOPs during ETRe. C 2007 on the forecast skill of NWP models Slide 16 DFG Begutachtung Bad Honeff 10/11. Januar 2008
