Realisation of the collaboration with ALADIN as the best option for HIRLAM for non-hydrostatic and meso-scale modelling. A whole lot of contacts,
discussions and preparations were made to this aim and it entailed a lot of contacts with both ALADIN and HIRLAM managers during this time. Involvement with the independent evaluation of the Project. Getting support for the new Programme (HIRLAM-A) and preparing for this. writing and coordinating new MoU for HIRLAM-A and a Cooperation Agreement with ALADIN at the same time. Recruiting the new Management Group. took over at the start of 2006. Head of Section, Model and analyis research, SMHI Res. Dept. 2006- Staff, planning and financial responsibility for 11-12 scientists. There are many contacts across the institute and in Sweden, e.g. Defence force, with whom the work is disussed with requests, plans and reports. Function as expert in many NWP issues in the instute, in groups and making planning documents. Organising and supervising research projects with EUMETSAT, Swedish Space Agency and EU projects (SEAMOCS and PREVIEW). SMHI representative for SEAMOCS and collaboration withlund University. Work on forest damage and ERA-40 in PREVIEW (WINDSTORM). European contacts and representative in SRNWP and HIRLAM and ALADIN contacts. Partaking in the overall Research management (group). Member in COST ES0702 and chairman of Working Group 2. External projects are financed by the Swedish National Space Board in assimilation cloud affected radiances and high resolution analysis as well as by SMHI and EUMETSAT. The EU FP7 Project EURO4M is another activity involving regional re-analysis and downscaling.
