Short summary
Short summary
This study presents the research design and first results of the DryTrees project, which investigates drought stress in Central European beech and oak forests. By combining continuous in-situ measurements of tree water balance with drone-, satellite-, and meteorological data, the project assesses how site-specific soil properties influence tree vitality and drought susceptibility. The integrative approach supports the development of site-adapted, climate-resilient forest management strategies.

Short summary
The study examines how new satellite images can be used to create detailed maps of Earth’s surface height. Analysis of Sentinel-1C data shows that very short time gaps between images produce the most accurate results in the study area, while longer gaps reduce quality, especially over forests and steep terrain. The findings give insights on the data quality achievable by 1-day repeat-pass interferometry by Sentinel-1.
