    Sammanfattning : Abstract in Undetermined To improve our knowledge of climate change and its impacts on ecosystem services, and to inform local people and governments that need assistance with the development of mitigation and adaptation strategies, climate impacts need to be understood urgently at the smaller scale. On one hand, the microclimate/topoclimate is known to be strongly decoupled from the general macroclimate of the freely circulating atmosphere and cannot reliably be inferred from climate station data or conventional climate models.
