Analysis of Land Surface Dynamics in Ukraine Observed by Satellite Sensors
(2020-06-18)
Land surface changes, induced by anthropogenic or climatic drivers, can dramatically impact ecosystem functioning. The growing amount of data from remote sensing and complementary data sources greatly supports the ...
Investigations to quantify individual exposure to solar ultraviolet erythemal radiation including cloud meteorological impact
(2020-07-09)
Combined meteorological and dosimetric ultraviolet (UV) erythemal radiation (UVER) measurements were performed in 2016 and 2017. Based on collected data sets the actual UVER exposure of outdoor working probands is determined ...
Improvement of hail detection and nowcasting by synergistic combination of information from polarimetric radar, model predictions, and in-situ observations
(2020-10-21)
Large hail can pose a major threat to people, infrastructure, and property. While polarimetric radar observations enable us to reliably detect hail, discrimination of hail size and strategies to nowcast and predict hail ...
Underwater flight in sea turtles and plesiosaurs: Dissection, muscle reconstructions, analog models, and finite element structure analyses inform on flipper twisting and muscle forces in plesiosaurs
(2020-08-13)
This dissertation contributes to our understanding of plesiosaur locomotion by providing foreflipper and hindflipper muscle reconstructions and studying aspects of their muscle physiology (functions, forces, muscle length ......
High Performance Computing in Basin Modeling: Simulating Mechanical Compaction with the Level Set Method
(2020-07-09)
The evolution of sedimentary basins is a complex set of processes developing over millions of years. Often, tectonic activity will create accommodation space that is filled in with sediments. These sediments undergo changes ...
Modeling water availability for smallholder farming in inland valleys under climate and land use / land cover change in Dano, Burkina Faso
(2020-05-05)
Effective water management in inland valley catchments is crucial for adaptation to the adverse impact of climate change and land use and land cover change (LULCC) on smallholder farming systems, poverty reduction, attaining ...
New aspects of deglaciation in southern Norway: Climate variability derived from surface exposure ages of Late Quaternary and Holocene landforms
(2020-01-30)
The investigation of periglacial and related landforms in South Norway is of high interest for exploring timings of deglaciation and to assess their geomorphological connectivity to palaeoclimatic changes during the Late ...
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 ...
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, ...
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 ...
