Abstract Eddy covariance sites are ideally suited for the study of extreme events on ecosystems as they allow exchange trace gases and energy fluxes between lower atmosphere to be directly measured a continuous basis. However, standardized definitions hydroclimatic extremes needed render studies comparable across sites. This requires longer datasets than available from on-site measurements in order capture full range climatic variability. We present dataset drought indices based...
Abstract Forests play a major role in the global carbon cycle, and droughts have been shown to explain much of interannual variability terrestrial sink capacity. The quantification drought legacy effects on ecosystem fluxes is challenging task, research scale remains sparse. In this study we investigate delayed response an extreme event cycle mixed deciduous forest site ’Hohes Holz’ (DE-HoH) located Central Germany, using measurements taken between 2015 2020. Our analysis demonstrates that...
Abstract Functional metal‐polymer nanocomposites are required for highly tailored surface properties and coatings. However, past approaches like cosputtering, physical evaporation, or plasma polymerization can not retain the functionality of polymer matrix produce nanoparticles. A new kind codeposition nanocomposite thin films is presented via combination a gas aggregation cluster source (GAS) initiated chemical vapor deposition (iCVD) in common GAS+iCVD vacuum system. iCVD delivers...
High-entropy alloy nanoparticles (HEA NPs) represent a promising material class with significant potential in various applications like heterogeneous catalysis or magnetic devices, due to their exceptional compositional tunability arising from the synergistic interplay of multiple elements within single particle. While laser-synthesized, ligand-free colloidal HEA NPs have already been reported, underlying formation mechanism remains unknown, particularly underexplored preference amorphous...
Water potential is a key driver of fluxes within natural ecosystems, governing water flow and its direction. Understanding plant hydraulics essential in the context climate change, as it helps evaluate suitability species for specific locations. Plant potential, response to environmental changes, plays pivotal role this assessment. Traditionally, measurement potentials has been conducted destructively intermittently, often employing time-consuming techniques e.g. using...
Forests play an important role in climate regulation due to carbon sequestration. However, a deeper understanding of forest flux dynamics is often missing lack information about structure and species composition, especially for non-even-aged species-mixed forests. In this study, we integrated field inventory data deciduous Germany into individual-based model investigate daily fluxes examine the tree size composition stand productivity. This approach enables reproduce derived from eddy...
Increasing the efficiency of solar thermal collectors is extremely important as they are essential for many applications, ranging from UV up to NIR spectral range, water heating systems micro-electromechanical systems. In this work, a plasmonic multilayer nanocomposite thin-film system that efficiently absorbs radiation across an extended range was simulated and experimentally tested. Novel our approach, copper nanoparticles in alumina matrix were chosen material. Compared other materials...
The 2018–2019 Central European drought had a grave impact on natural and managed ecosystems, affecting their health productivity. We examined patterns in hyperspectral VNIR imagery using an unsupervised learning approach to improve ecosystem monitoring the understanding of grassland responses. main objectives this study were (1) evaluate application simplex volume maximisation (SiVM), method, for detection stress high-dimensional remote sensing data at scale (2) analyse contributions...

<p>Adapting the impacts of climate change is a great challenge. To facilitate forest adaptation long-term and forward-looking decisions must be made today since they have to valid for several decades. Therefore, fundamental knowledge future tree species which are more resilient than trees growing in forests necessary.</p><p>To give local foresters basis their decisions, we use so-called analogue region method. With this method aim find regions Europe...
