Spaceborne SAR Remote Sensing for Monitoring of Vegetation Dynamics in Arid and Semi-arid Environment
(2020-04-22)
Drylands are under constant threat from multiple stresses and challenges, which occur as a result of a complex interaction of natural processes, and human-induced processes caused by unsustainable land use practices, leading ...
Die Implementierung des Themas Fernerkundung in den Schulunterricht der Sekundarstufe I durch das neue MINT-Wahlpflichtfach "Geographie-Physik": eine Studie zur praktischen Schulfachgestaltung im Differenzierungsbereich der Jahrgangsstufen 8 und 9 an Gymnasien in Nordrhein-Westfalen am Beispiel des Gymnasiums Siegburg Alleestraße
(2021-10-26)
Schülerinnen und Schüler werden in ihrer Alltagswelt seit dem letzten Jahrzehnt immer früher mit Satellitenbildern konfrontiert. Durch den Wetterbericht und die Nachrichtensendung im Fernsehen oder durch virtuelle Globen ...
Climate field reconstructions from pollen and macrofossil syntheses using Bayesian hierarchical models
(2020-01-09)
Studying past climate states is important to understand climate changes and climate variability on centennial to orbital timescales, to analyze the reaction of the Earth system to large-scale changes in external forcings, ...
Vorkommen Antibiotika-resistenter Bakterien in der aquatischen Umwelt: Zusammenhänge zu dem Vorkommen antibiotisch wirkender Substanzen
(2022-01-05)
Ein Anstieg der Resistenzen bei gleichzeitiger Stagnation hinsichtlich der Ent-wicklung neuer Antibiotika ist vor allem für Infektionen mit Gram-negativen Bakte-rien kritisch. Die WHO spezifizierte bereits 2014 ...
Mining and small-scale farming in the Andes: Socio-environmental roots of land-use conflict
(2020-04-08)
The Peruvian Andes are one of the most important water sources for the country. Therefore, their exploitation might pose critical threats for local farming activities, national economy, and water quantity and quality. At ...
Linking slopes to the wetland: Hillslope hydrology and associated nitrate transport in a tropical valley bottom wetland
(2022-11-07)
Valley bottom wetlands are regarded as a white hope for enhancing food security in East Africa. Due to their prolonged water availability, they buffer some of the effects of climate change and further offer fertile soils ...
In situ observations of reaction and transport phenomena during silicate glass corrosion by fluid-cell Raman spectroscopy: Method development and applications
(2020-07-06)
Borosilicate glass is the preferred material for the immobilization of high-level nuclear waste and an important material for various industries. Silicate glasses, however, are prone to corrosion by aqueous solutions, which ......
On the importance of meteorological parameters in processes affecting the chemical composition of the tropsphere
(2022-12-22)
Investigating the interaction of meteorology and chemistry in the troposphere is important for the identification of the processes which drive the evolution of tropospheric composition in a changing climate. It does not ...
Time Filter Assisted Deep Learning to Predict Air Pollution
(2023-07-13)
Exposure to ground-level ozone harms human health as well as the entire ecosystem, so accurate prediction of ozone exposure is of particular importance. Machine learning (ML), and deep learning (DL) in particular, has ...
Integrated Terrestrial Simulations over Europe: Groundwater-Atmosphere Feedbacks with Altered Water Tables Including the Effect of Recent Droughts
(2023-08-08)
The groundwater flow is an essential part of the terrestrial system encompassing the atmosphere, land surface, and subsurface. In past research, there was usually no focus on water in the subsurface because climate models ...
