Das Projekt "Forschergruppe (FOR) 2416: Space-Time Dynamics of Extreme Floods (SPATE), Research group (FOR) 2416: Space-Time Dynamics of Extreme Floods (SPATE)" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Universität Bochum, Lehrstuhl für Hydrologie, Wasserwirtschaft und Umwelttechnik.River floods are extremely important to society because of their potential damage and fatalities. Floods are also very interesting research subjects because of the intriguing non-linear interactions and feedbacks involved, interesting issues of generalisation and the need for investigating them in an interdisciplinary way. Extreme floods are not very well understood to date but new, high resolution data and new concepts for quantifying interactions promise a major breakthrough of a body of research carried out in a coordinated way. The objective of this Research Unit is to understand in a coherent way the atmospheric, catchment and river system processes and their interactions leading to extreme river floods and how these evolve in space and time. An innovative and coherent concept has been adopted in order to maximise the potential of the cooperation between the research partners which consists of three layers of integration: research themes focusing on the science questions, subprojects revolving around specific research tasks, and a joint study object of extreme floods in Germany and Austria. Using scales as a binding element, the research plan is organised into the research themes of event processes, spatial (regional) variability, temporal (decadal) variability, and uncertainty and predictability. The members of the Research Unit have been selected to obtain a team of leading experts with expertise that is complementary in terms of processes, methods and regional knowledge. The cooperation and communication strategy will be implemented through themed cluster groups, combining several subprojects, regular meetings of the cluster groups, an annual project symposium and a private cloud facilitating data exchange on the joint study object. Equal opportunity policies will be adopted and female and early career scientists will be promoted in a major way. Overall, the outcomes of the Research Unit will constitute a step change in the understanding of the coupled system of flood processes in the atmosphere, catchments and rivers which will have major implications for a range of sciences and the society.

Das Projekt "Gross N transformations and N2O fluxes in biochar-amended soils" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Universität Gießen, Institut für Pflanzenökologie (Botanik II).Recently, the application of biochar to soils has been discussed as a win-win-win strategy to improve soil fertility, sequester carbon, reduce greenhouse gas (GHG) emissions, and to enable CO2-negative energy production from renewable feedstock. First results suggest that biochar application affects the N transformations in the soil - The interactions between biochar and soil N transformations are still poorly understood. The aim of this project is to quantify the simultaneously occurring gross N transformations and sources of N2O fluxes in soils after biochar application. The methodology developed by C. Müller and established at the Department of Plant Ecology (15N labeling-tracing-modeling) (2-5) will be used to investigate the effect of biochar on soil N dynamics. Three 15N-tracing studies will be conducted to evaluate the short-term, intermediate and longer-term effects of biochar on N dynamics: (1) a study using 15N-labelled biochars (adapt technique for biochar); (2) a study examining intermediateterm effects in a biochar-hydrochar field study that started in April 2011 at the Dept. of Plant Ecology, and (3) a study in an European field experiment where fully randomized biochar plots were installed in 2009. The study is designed in such a way that Bachelor- and Master studies will address certain aspects in support of the main study. A process-based understanding of the soil N dynamics is key to evaluate if biochar may be a suitable global-change mitigation tool.

Das Projekt "Forest management in the Earth system" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Max-Planck-Institut für Meteorologie.The majority of the worlds forests has undergone some form of management, such as clear-cut or thinning. This management has direct relevance for global climate: Studies estimate that forest management emissions add a third to those from deforestation, while enhanced productivity in managed forests increases the capacity of the terrestrial biosphere to act as a sink for carbon dioxide emissions. However, uncertainties in the assessment of these fluxes are large. Moreover, forests influence climate also by altering the energy and water balance of the land surface. In many regions of historical deforestation, such biogeophysical effects have substantially counteracted warming due to carbon dioxide emissions. However, the effect of management on biogeophysical effects is largely unknown beyond local case studies. While the effects of climate on forest productivity is well established in forestry models, the effects of forest management on climate is less understood. Closing this feedback cycle is crucial to understand the driving forces behind past climate changes to be able to predict future climate responses and thus the required effort to adapt to it or avert it. To investigate the role of forest management in the climate system I propose to integrate a forest management module into a comprehensive Earth system model. The resulting model will be able to simultaneously address both directions of the interactions between climate and the managed land surface. My proposed work includes model development and implementation for key forest management processes, determining the growth and stock of living biomass, soil carbon cycle, and biophysical land surface properties. With this unique tool I will be able to improve estimates of terrestrial carbon source and sink terms and to assess the susceptibility of past and future climate to combined carbon cycle and biophysical effects of forest management. Furthermore, representing feedbacks between forest management and climate in a global climate model could advance efforts to combat climate change. Changes in forest management are inevitable to adapt to future climate change. In this process, is it possible to identify win-win strategies for which local management changes do not only help adaptation, but at the same time mitigate global warming by presenting favorable effects on climate? The proposed work opens a range of long-term research paths, with the aim of strengthening the climate perspective in the economic considerations of forest management and helping to improve local decisionmaking with respect to adaptation and mitigation.
Das Projekt "PGS: POLSTRACC / GWLCYCLE and SALSA: Teilnahme der universitären Partner an einer koordinierten Arktis Mission mit HALO" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Johann Wolfgang Goethe-Universität Frankfurt am Main, Institut für Atmosphäre und Umwelt.Ziel diesen Antrags ist die Teilnahme der universitären Partner an den Messungen der Kampagne PGS (POLSTRACC/ GWLCYCLE/ SALSA), die im Winter 2015/2016 durchgeführt werden sollen. An der geplanten HALO Kampagne sind die Universitäten Frankfurt, Mainz, Heidelberg und Wuppertal beteiligt. Die Universität Mainz ist kein voller Partner dieses Antrages, da es kein Projekt der Universität Mainz (AG Prof. Peter Hoor) in der letzten Phase des Schwerpunktprogramms gab. Der finanzielle Teil der geplanten Aktivitäten der Universität Mainz soll daher über die Universität Frankfurt abgewickelt werden. Der wissenschaftliche Beitrag der Universität Mainz ist allerdings in einer ähnlichen Weise dargestellt wie für die anderen universitären Partner. Das Ziel von PGS ist es, Beobachtungen einer großen Zahl verschieden langlebiger Tracer zur Verfügung zu stellen, um chemische und dynamische Fragestellungen in der UTLS zu untersuchen (POLSTRACC und SALSA) und die Bildung und Propagation von Schwerwellen in der Atmosphäre zu untersuchen. (GWLCYCLE). Die Universitäten Frankfurt und Wuppertal schlagen vor hierfür GC Messungen von verschieden langlebigen Spurengasen und von CO2 (Wuppertal) durchzuführen. Die Universität Mainz schlägt den Betrieb eines Laser Spektrometers für schnelle Messungen von N2O, CH4 und CO vor und die Universität Heidelberg plant Messungen reaktiver Chlor und Bromverbindungen mit Hilfe der DOAS Technik. Die wissenschaftlichen Studien, die mit den gewonnen Daten durchgeführt werden sollen, werden im Antrag umrissen. Es sind Studien zu Herkunft und Transport von Luftmassen in der UTLS, zu Transportzeitskalen und zum chemischen Partitionierung. Es sei an dieser Stelle darauf hingewiesen, dass diese wissenschaftlichen Arbeiten zwar hier umrissen werden, die Studien selbst aber aufgrund der begrenzten Personalförderung und der kurzen Laufzeit nicht Teil dieses Antrags sind. Ziel dieses Antrags ist es, die Vorbereitung und Integration der Messgeräte zu ermöglichen, die Messungen durchzuführen und die Daten für die Datenbank auszuwerten. Wir beantragen daher hier den universitären Anteil an den Missionskosten (incl. Zertifizierung der Gesamtnutzlast und der Flugkosten), die Personalmittel, Reisekosten und Verbrauchskosten für die Durchführung der Messungen.
Das Projekt "Schwerpunktprogramm (SPP) 1294: Bereich Infrastruktur - Atmospheric and Earth system research with the 'High Altitude and Long Range Research Aircraft' (HALO), NAWDEX - North Atlantic Waveguide and Downstream Impact Experiment" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Ludwig-Maximilians-Universität München, Meteorologisches Institut.The North Atlantic Waveguide and Downstream Impact Experiment (NAWDEX) aims to provide the foundation for future improvements in the prediction of high impact weather events over Europe. The concept for the field experiment emerged from the WMO THORPEX program and contributes to the World Weather Research Program WWRP in general and to the High Impact Weather (HIWeather) project in particular. An international consortium from the US, UK, France, Switzerland and Germany has applied for funding of a multi-aircraft campaign supported by enhanced surface observations, over the North Atlantic and European region. The importance of accurate weather predictions to society is increasing due to increasing vulnerability to high impact weather events, and increasing economic impacts of weather, for example in renewable energy. At the same time numerical weather prediction has undergone a revolution in recent years, with the widespread use of ensemble predictions that attempt to represent forecast uncertainty. This represents a new scientific challenge because error growth and uncertainty are largest in regions influenced by latent heat release or other diabatic processes. These regions are characterized by small-scale structures that are poorly represented by the operational observing system, but are accessible to modern airborne remote-sensing instruments. HALO will play a central role in NAWDEX due to the unique capabilities provided by its long range and advanced instrumentation. With coordinated flights over a period of days, it will be possible to sample the moist inflow of subtropical air into a cyclone, the ascent and outflow of the warm conveyor belt, and the dynamic and thermodynamic properties of the downstream ridge. NAWDEX will use the proven instrument payload from the NARVAL campaign which combines water vapor lidar and cloud radar, supplemented by dropsondes, to allow these regions to be measured with unprecedented detail and precision. HALO operations will be supported by the DLR Falcon aircraft that will be instrumented with wind lidar systems, providing synergetic measurements of dynamical structures. These measurements will allow the first closely targeted evaluation of the quality of the operational observing and analysis systems in these crucial regions for forecast error growth. They will provide detailed knowledge of the physical processes acting in these regions and especially of the mechanisms responsible for rapid error growth in mid-latitude weather systems. This will provide the foundation for a better representation of uncertainty in numerical weather predictions systems, and better (probabilistic) forecasts.
Das Projekt "European Investment Bank - Water Management" wird/wurde ausgeführt durch: Jena-Optronik GmbH.BACKGROUND: The Kingdom of Jordan belongs to the ten water scarcest countries in the world, and climate change is likely to increase the frequency of future droughts. Jordan is considered among the 10 most water impoverished countries in the world, with per capita water availability estimated at 170 m per annum, compared to an average of 1,000 m per annum in other countries. Jordan Government has taken the strategic decision to develop a conveyor system including a 325 km pipe to pump 100 million cubic meters per year of potable water from Disi-Mudawwara close to the Saudi Border in the south, to the Greater Amman area in the north. The construction of the water pipeline has started end of 2009 and shall be finished in 2013. Later on, the pipeline could serve as a major part of a national water carrier in order to convey desalinated water from the Red Sea to the economically most important central region of the country. The conveyor project will not only significantly increase water supplies to the capital, but also provide for the re-allocation of current supplies to other governorates, and for the conservation of aquifers. In the context of the Disi project that is co-funded by EIB two Environmental and Social Management Plans have been prepared: one for the private project partners and one for the Jordan Government. The latter includes the Governments obligation to re-balance water allocations to irrigation and to gradually restore the protected wetlands of Azraq (Ramsar site) east of Amman that has been depleted due to over-abstraction by re-directing discharge of highland aquifers after the Disi pipeline becomes operational. The Water Strategy recognizes that groundwater extraction for irrigation is beyond acceptable limits. Since the source is finite and priority should be given to human consumption it proposes to tackle the demand for irrigation through tariff adjustments, improved irrigation technology and disincentive to water intensive crops. The Disi aquifer is currently used for irrigation by farms producing all kinds of fruits and vegetables on a large scale and exporting most of their products to the Saudi and European markets and it is almost a third of Jordan's total consumption. The licenses for that commercial irrigation were finished by 2011/12. Whilst the licenses will be not renewed the difficulty will be the enforcement and satellite based information become an important supporting tool for monitoring. OUTLOOK: The ESA funded project Water management had the objective to support the South-North conveyor project and the activities of EIB together with the MWI in Jordan to ensure the supply of water for the increasing demand. EO Information provides a baseline for land cover and elevation and support the monitoring of further stages. usw.
