Das Projekt B1 'Allometrie und Raumbesetzung von krautigen und holzigen Pflanzen' ist Teil des Sonderforschungsbereiches 607 Wachstum und Parasitenabwehr und befindet sich bereits in der vierten Phase des seit 1998 laufenden Forschungsprojektes. Bisher wurde im Projekt B1 die Allometrie als Resultat der pflanzeninternen Steuerung der Allokation untersucht. Auf Individuenebene wurden Allometrie und ihre Veränderung für verschiedene Baumarten in verschiedenen ontogenetischen Stadien untersucht. Auf Bestandesebene wurden die self-thinning-Linien von Yoda und Reineke für krautige bzw. holzige Pflanzenbestände analysiert. Bisherige Allometriebestimmungen erbrachten für diese Arten zwar ähnliche Größenordnung aber auch charakteristische Unterschiede, die Ausdruck spezifischer Strategien der Raumbesetzung und -ausbeutung widerspiegeln. Die bisher vereinzelten Auswertungen sollen in Phase IV in eine übergreifende Analyse (versch. Arten, ontogenetische Stadien, Konkurrenzsituationen, Störfaktoren) der Allometrie auf Pflanzen- und Bestandesebene münden.
Die Erkennung von Veränderungen der Landbedeckung der Erdoberfläche auf der Basis von satellitengestützten Fernerkundungsdaten ist seit Jahrzehnten ein sehr aktives Forschungsfeld. Das Ziel des Landschaftsveränderungsdiensts ist es, freie Copernicus-Satellitendaten für eine automatische Ableitung von Landbedeckungsänderungen zu nutzen und diese Informationen regelmäßig für einzelne Landschaftselemente (z.B. für Waldgebiete, Wasserflächen, Landwirtschaftsflächen usw.) über einen Web Service bereitzustellen. Copernicus Daten eignen sich aufgrund der hohen zeitlichen (ca. 3-5 Tage, je nach Sensor) und mittleren räumlichen Auflösung (ab 10m) ideal für eine regelmäßige bundesweite flächendeckende Analyse der Landbedeckung. Um eine hohe Bearbeitungsleistung zu erreichen wird die 'Copernicus Data and Exploitation Platform - Deutschland' (CODE-DE) für die Datenverarbeitung und -analyse genutzt. Es können aktuelle und konsistenteste Informationen über Landdeckungsänderungen abgeleitet werden, um kontinuierlich Geodaten in einer einheitlichen Qualität zu pflegen (siehe Abbildung 1). Andererseits können die gewonnenen Informationen genutzt werden, um statistisch relevante Geoinformationen zur quantitativen Beschreibung der UN-SDG-Indikatoren zu extrahieren. Die 2015 verabschiedete Agenda 2030 mit 17 Entwicklungszielen (SDG) und 169 Unterzielen verknüpft das Prinzip der Nachhaltigkeit mit der ökonomischen, ökologischen und sozialen Entwicklung. Die Umsetzung erfordert einen soliden Überprüfungsmechanismus. Dieser soll durch eine regemäßige nationale Erfassung von ca. 200 definierten UN-SDG-Indikatoren erfolgen, mit dem Ziel Fortschritte zu monitoren und die Politik zu informieren.
The aim of the current research is to identify regional sources and trans-boundary flow leading to the observed salinity of Lake Tiberias (LT) -also known as the Sea of Galilee or Lake Kinneret-, and its surroundings, which is considered the only natural surface fresh water reservoir of the area. The current study will include all sources of brines in the Tiberias Basin (TB) with specific emphasis of the relationship between the brines from the Ha'on and Tiberias Regions (HTR).The tasks will be achieved by a multidisciplinary approach involving: (i) numerical modelling of density-driven flow processes (i.e., coupled heat and dissolution of evaporites), (ii) hydrochemical studies, supplemented by investigations of subsurface structures.(i) Numerical modelling will be carried out by applying the commercial software FEFLOW® (WASY, GmbH) complemented with the open source code OpenGeoSys developed at the UFZ of Leipzig (Wang et al., 2009). The final goal is to build a 3D regional-scale model of density-driven flow that will result in: (1) revealing the different interactions between fresh groundwater and natural salinity sources (2) elucidate the driving mechanisms of natural brines and brackish water body's movements.(ii) Hydrochemical study will include major, minor and, if possible, rare earth elements (REE) as well as isotope studies. The samples will be analysed at the FU Berlin and UFZ Halle laboratories. Geochemical data interpretation and inverse modelling will be supported by PHREEQC. Hydrochemical field investigations will be carried out in Tiberias basin and its enclosing heights, i.e. the Golan, Eastern Galilee and northern Ajloun in order to search for indications of the presence of deep, relic saline groundwater infested by the inferred Ha'on mother-brine. The current approaches will be supplemented by seismic and statistical data analysis as well as GIS software applications for the definition of the subsurface structures. The key research challenges are: building a 3D structural model of selected regions of TB, adapting both structural and hydrochemical data to the numerical requirements of the model; calibrating the 3D regional-scale model with observational data. The results of this work are expected to establish suitable water-management strategies for the exploitation of freshwater from the lake and from the adjacent aquifers while reducing salinization processes induced by both local and regional brines.
GLORIA combines a Michelson interferometer with a detector array of 128 x 128 pixels and will be the first 2D infrared limb imaging spectrometer worldwide. It is designed for HALO and will measure the distribution of temperature and a considerable number of trace constituents along with cloud mapping with unprecedented spatial resolution in the free troposphere and lower stratosphere. It is an essential contribution to the HALO demo missions TACTS, POLSTRACC, and CIRRUS-RS. Imaging Fourier transform spectrometers impose a number of challenges with respect to instrument calibration / characterisation and for algorithm development. The work of the first proposal focused on characterisation and modeling of the instrument and on the development of methods and algorithms which are capable of generating calibrated spectra with high accuracy. Accurately calibrated spectra are a prerequisite for the retrieval of atmospheric parameters and the scientific data exploitation. Within this renewal proposal the developed characterisation methods will be applied to the instrument in flight configuration, and the new algorithms will be used to generate highly accurate calibrated spectra from the raw interferograms measured during the HALO demo missions. The work will be completed by a thorough error analysis for the calibrated spectra. Finally, instrument settings, calibration scenario and data processing shall be optimised with respect to data quality. This proposal contributes to the development of high technology sensors and instruments for the use on HALO.
ROBUST DSC aims to develop materials and manufacturing procedures for Dye Sensitized Solar Cells (DSC) with long lifetime and increased module efficiencies (7Prozent target). The project intends to accelerate the exploitation of the DSC technology in the energy supply market. The approach focuses on the development of large area, robust, 7Prozent efficient DSC modules using scalable, reproducible and commercially viable fabrication procedures. In parallel with this objective, more fundamental research, employing new materials and device configurations, will target increasing the efficiency of labscale DSC to 14Prozent. Progress on labscale devices will be fed directly into module development. The approach is based on the use of innovative low-cost materials, scalable manufacturing techniques, predictive device models and in-and outdoor lifetime testing. A sound and scientific understanding of the basic procedures to manufacture the cells and a thorough knowledge of the fundamental processes in the cell are important tools for our success. The partnership consists of: two SMEs (Orionsolar and G24i) that are committed to large-scale production of DSC, one industry (Corning) that has proven experience on inorganic frits for sealing of a variety of applications, three research institutes (ECN, IVF, FISE) with expertise in the field of long-term testing, up-scaling and module fabrication and four academic partners, world leaders in both new materials and concepts, and in fundamental research on cell function and modelling (EPFL, IMPERIAL, ICIQ, UAM). We anticipate that this project will result in the demonstration of a new scalable, low cost, photovoltaic technology. It will therefore form the basis of a potentially substantial business opportunity aiming at developing a new solar cell product with cost and payback characteristics strongly advantaged over existing technologies.
The dissection of complex traits into their underlying genetic components has become a major research area in plant breeding. As a consequence, significant progress has been made in the development of biometric methods for quantitative trait locus (QTL) analysis. Experimental studies on detection, mapping and unbiased estimation of QTL effects are generally performed on randomly derived progenies. For efficient integration of marker-assisted selection into classical breeding programs it seems indispensable to minimize expenditures by using selected populations for QTL detection. Thus, the development of new theoretical concepts for unbiased estimation of QTL effects in non-random populations is the focus of this study. Combining available QTL mapping methods, quantitative genetics, computer simulations, and analysis of experimental data, our goals are to develop biometric methods to apply QTL mapping and resampling techniques to non-random breeding populations such as Advanced-Backcross-populations (AB-QTL) or populations subjected to selection to obtain unbiased estimates of QTL effects and to allow full exploitation of the potential of marker-assisted selection. Our investigations will provide valuable analysis tools for optimizing marker-assisted selection programs. Furthermore, we aim to make recommendations on the integration of QTL analyses into practical breeding programs. Owing to the cooperative effort of research groups from Germany, Australia and the USA we expect that our results will be broadly distributed to the scientific community and practical plant breeding.
The research projects of PMOD/WRC aim at understanding the terrestrial radiation budget and the influence of the Sun on the terrestrial climate. The latter is in the central focus of today's world-wide climate research and is termed 'Space Weather' if the emphasis is on short term events and it is termed 'Space Climate, if climate implications are investigated. From the point of view of the activities of PMOD/WRC, the most interesting aspect of research in solar physics is that the radiance output of the Sun itself is variable. The goal of solar physics research at PMOD/WRC is therefore, to advance our understanding of the origin of these variations in order to be able to reconstruct the solar influence on the climate in the past. The SNF grant supports: A) Interpretation of data from active space experiments: Presently, there are two active space experiments built by PMOD/WRC: VIRGO on SoHO since December 1995, which is still operational, and SOVIM on the ISS since February 2008; B) Preparing for the scientific exploitation of the upcoming space experiment LYRA/PROBA2 and PREMOS on PICRAD (with launch in 2009); C) Investigating the origin of the solar radiance variability in the UV by exploring the lower chromosphere with helioseismological methods. Since 1996 the space experiment VIRGO/SoHO is monitoring the Total (TSI) and spectral Solar Irradiance. The homogeneous VIRGO data provide a crucial element in the construction of the TSI composite and thus, VIRGO provides a key observation to investigate the influence of the Sun on the terrestrial climate. The PMOD/WRC is involved in three new space missions that continue the observations of total and spectral solar irradiance: SOVIM on the ISS since February 2008 and with launch in 2009 LYRA on PROBA2, and PREMOS on PICARD. SOVIM on the ISS continues to monitor total and spectral solar irradiance with instrumentation similar to VIRGO/SOHO. Together with the two other experiments SOLSPEC and SolACES on the same platform, which observe the spectral irradiance from the EUV to the near infrared, our knowledge of the spectral redistribution during TSI changes will be improved and provide a sound basis for understanding of solar irradiance variability. LYRA/PROBA2 observations will be used for a climate-chemistry model that was developed at PMOD/WRC as part of an ETH-funded Poly-project. When LYRA data become available we will use a special middle atmosphere version of this CCM model, SOCOL-I, for now-casting the state of the upper atmosphere as reaction to the UV irradiance as observed by LYRA/PROBA2. This now casting is primarily aimed at testing our understanding of the chemical and dynamical processes induced by the variable solar UV irradiance, but if successful, our now casting product is a welcome additional input for space weather applications. Until the launch of PROBA2, this subproject is aimed at preparing the computer model for its operational use.
The project examines funding of environmental technology development and commercialisation. The objectives are to: measure the performance of existing funding schemes (emphasising commercial-type funding); determine how environmental aspects are dealt with; identify obstacles; and suggest evolution of new schemes. Eight project work packages address these objectives, and also include development of environmental technology typologies, analysis of funding gaps, and comparison to Japan and the USA. The project supports SSP 5A by connecting policy and practice, linking researchers from across the EU, and using wide consultation to disseminate knowledge and maximise exploitation of research results. Consortium partners are drawn from five EU states, and have expertise and networks in private and public environmental technology funding and technology development processes. Stakeholder consultation with private and public funders, developers, academics, policy makers and NGOs will support research and knowledge dissemination. Consultation will include major public conferences and forums, sector-specific focus groups, and workshops to test analysis and geographic variations. Consultation and publication and dissemination of the final report will spur innovation by private and public funders, supporting knowledge exploitation after project completion. Research will emphasise private sector solutions, but will also include public-private partnerships, which are innovative measures that can assist in closing the funding gap. The varying applicability of such partnerships across different EU states will also be considered. The two project deliverables will be a database containing research and contact information, and a widely published final report that will integrate all research and recommendations.
