Cluster analysis of European surface ozone observations for evaluation of MACC reanalysis data
(2015-04-22)
The high density of European surface ozone monitoring sites offers good opportunities for investigation of the regional ozone representativeness and for evaluation of chemistry climate models. In this thesis we analyze ...
The Impact of Sensor Characteristics and Data Availability on Remote Sensing Based Change Detection
(2014-12-04)
Land cover and land use change are among the major drivers of global change. In a time of mounting challenges for sustainable living on our planet any research benefits from interdisciplinary collaborations to gain an ...
3D-Modeling of unsaturated flow dynamics and pattern: Potentials and Limitations at different spatial and temporal scales
(2016-06-14)
The aim of this thesis was to evaluate the suitability of the physically based, distributed 3D hydrological model HydroGeoSphere for the simulation of spatio-temporal soil moisture variability as well as unsaturated flow ...
On the probabilistic evaluation of decadal and paleoclimate model predictions
(2017-11-27)
The development of climate prediction systems for years to decades is an area of current research, as these time scales are important e.g. for the planning horizon of decision-makers. Those prediction systems can be improved ...
Atmospheric Downscaling using Multi-Objective Genetic Programming
(2017-10-10)
Numerical models are used to simulate and to understand the interplay of physical processes in the atmosphere, and to generate weather predictions and climate projections. However, due to the high computational cost of ...
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 ...
