ABSTRACT Relative homogenization methods assume that measurements of nearby stations experience similar climate signals and rely therefore on dense station networks with high‐temporal correlations. In developing countries such as Peru, however, often suffer from low‐station density. The aim this study is to quantify the influence network density homogenization. To end, method HOMER was applied an artificially thinned Swiss network. Four experiments, reflecting different approaches, were...
ABSTRACT In situ climatological observations are essential for studies related to climate trends and extreme events. However, in many regions of the globe, observational records affected by a large number data quality issues. Assessing controlling such datasets is an important, often overlooked aspect research. Besides analysing measurement data, metadata important comprehensive assessment. missing, but may partly be reconstructed suitable actions as station inspections. This study...
Abstract. Systematic data quality issues may occur at various stages of the generation process. They affect large fractions observational datasets and remain largely undetected with standard control. This study investigates effects such on results climatological analyses. For this purpose, we controlled daily observations manned weather stations from Central Andean area a an enhanced approach. The climate variables analysed are minimum maximum temperature precipitation. About 40 %...
Crown condition is considered as one of the most important indicators a tree’s vitality. As part monitoring program Long-term Forest Ecosystem Research, defoliation tree crowns in Swiss forests has been monitored on an annual time scale since 1985. This long-term data set makes it possible to track progress until trees die and take into account variety stress factors that may have played role this process.In forests, average mortality increased past decades. However, only occurred...
Der Zustand der Baumkrone ist ein wichtiger Indikator für die Vitalität eines Baumes. In Schweizer Wäldern wird Kronenzustand seit 1985 im Rahmen Sanasilva-Inventuren und 1994 als Teil des Forschungspro- gramms «Langfristige Waldökosystem-Forschung» erhoben. dieser Periode hat Waldes deut- lich abgenommen. Starke grossflächige Verschlechterungen zeigten sich insbesondere nach Trockensom- mern. Baumkronen auch Absterbewahrscheinlichkeit Baumes in den Folgejahren. Hauptursache...
Wälder sind eine wichtige Kohlenstoffsenke, stehen jedoch durch sich häufende Klimaextreme wie Hitze und Trockenheit zunehmend unter Druck. Nach 25 Jahren Monitoring an den 19 Standorten des Programms «Lang- fristige Waldökosystem-Forschung» zeigen Veränderungen in der Waldstruktur im Wachstum. Die Wäl- wurden generell dichter älter. Das Wachstum nahm sowohl Tief- als auch Hochlagen ab, vor allem bei Fichte, Tanne Buche. korreliert auf Einzelbaum- Bestandesebene mit Bestandesstruktur...
Il monitoraggio e lo studio dei boschi al Sud delle Alpi ci hanno consentito di approfondire le conoscenze sugli effetti cambiamenti climatici inquinamento atmosferico: frequenza intensità eventi siccitosi sono au- mentate; la qualità dell’aria negli ultimi 30 anni è sensibilmente migliorata in seguito all’adozione misure per riduzione emissioni, ma, certe zone, deposizioni azotate ozono destano ancora preoccupazione.
Wälder tragen zur Erneuerung des Grundwassers in Trinkwasserqualität bei. Wiederholte Untersuchungen zei- gen, dass die hohe Stickstoffdeposition immer noch zu erhöhten Konzentrationen von Nitrat im Sickerwasser aus Wäldern führen kann. Zu Nitratwerte Trinkwasser können Gesundheit für Mensch und Um- welt beeinträchtigen. Die Bodeninventur auf fünf ausgewählten Flächen Programms «Langfristige Wald- ökosystem-Forschung» zeigt, Stickstoffsättigung einem Teil der Flächen, trotz Rückgang Ein-...
The vitality of Scots pine ( Pinus sylvestris L.) is declining since the 1990s in many European regions. This was mostly attributed to occurrence hotter droughts, other climatic changes and secondary biotic stressors. However, it still not well understood which specific atmospheric trends extremes caused observed spatio-temporal dieback patterns. In Swiss Rhône valley, we identified negative precipitation anomalies between midsummer early autumn as main driver sudden decline events. Whereas...
The extraction and disposal of heat from lakes rivers is a large yet scarcely exploited source renewable energy, which can partly replace fossil fuel heating electrical cooling systems. Its use expected to increase in the near future, brings attention impacts discharging thermally altered water into aquatic Our review indicates that thermal discharge affects physical ecological processes, with recorded at all levels biological organization. Many situ studies found local effects (such as...
Abstract The loss of leaves and needles in tree crowns mortality are increasing worldwide, mostly as a result more frequent severe drought stress. Scots pine (Pinus sylvestris L.) is species that strongly affected by these developments many regions Europe Asia. So far, changes metabolic pathways metabolite profiles roots on the trajectory toward unknown, although they could contribute to better understanding mechanisms. Therefore, we linked long-term observations canopy defoliation with...
