To model potential future site-specific forest productivity, high quality data for both forest stands and climate are required. So far, the available climate data meet the requirements for forestry scientific questio...

This paper presents methods for analysing the impacts of different terrain parameters on cold air production, flow and cold air accumulation. These methods have been tested using a Digital Terrain Model (DTM) in combination with point source nocturnal temperature data observed during autochthonous calm and clear weather conditions. The gently undul...
