Task 2.1: Set-up meteorological data base for the different storm types. This includes observational data, gridded datasets like INCA, ECWMF analysis, ÖKS15, or EUROCORDEX runs, and historical information on windstorms.

Task 2.2: Spatially and temporally explicit local (i.e., stand level) wind damage events in different regions in Austria will be collected. Thereby damages from different storm types will be distinguished (Atlantic storms, Foehn storms, local thunderstorms). Sources of damage data will be an array of forest enterprises which cooperate with the project. Backbone of the damage data base will be the internal records of several management units of the Austrian Federal Forests (ÖBf AG) spread out over large parts of Austria. These records comprise of 1-2 decades of annual planned harvests and salvage from wind and other disturbances.

Task 2.3: Based on a a selection of wind damage events from the harvest records the exact timing of the damage events (+/- 1 day) will be identified in the field with the local forest managers. Care will be taken that overall the three distinguished storm types are well represented in this accurately located (space, time) damage events. Stand level forest information of stands around such identified damage events will be retrieved from forest management plans.

Task 2.4: Setting-up a digital data base including spatial visualization tools (GIS).
