Global SnowPack - MODIS - Daily

This product shows globally the daily snow cover extent (SCE). The snow cover extent is the result of the Global SnowPack processor's interpolation steps and all data gaps have been filled. Snow cover extent is updated daily and processed in near real time (3 days lag). In addition to the near real-time product (NRT_SCE), the entire annual data set is processed again after the end of a calendar year in order to close data gaps etc. and the result is made available as a quality-tested SCE product. There is also a quality layer for each day (SCE_Accuracy), which reflects the quality of the snow determination based on the time interval to the next "cloud-free" day, the time of year and the topographical/geographical location. The “Global SnowPack” is derived from daily, operational MODIS snow cover product for each day since February 2000. Data gaps due to polar night and cloud cover are filled in several processing steps, which provides a unique global data set characterized by its high accuracy, spatial resolution of 500 meters and continuous future expansion. It consists of the two main elements daily snow cover extent (SCE) and seasonal snow cover duration (SCD; full and for early and late season). Both parameters have been designated by the WMO as essential climate variables, the accurate determination of which is important in order to be able to record the effects of climate change. Changes in the largest part of the cryosphere in terms of area have drastic effects on people and the environment.

Assessment of formal, natural and social insurances: how to cope best with impacts of extreme events on grasslands for sustainable farming systems?

The impacts of climate change pose one of the main challenges for agriculture in Central Europe. In particular, an increase of extreme and compound extreme climate events is expected to strongly impact economic revenues and the provision of ecosystem services by agroecosystems. A highly relevant, still open question is how grassland farming systems can cope best with these climate risks to adapt to climate change. A prominently discussed economic instrument to relieve income risks is the formal insurance, but natural and social insurances are newly under discussion as well. Natural insurances include specific grassland management practises such as maintaining species-rich grasslands. Social insurances, in our terminology, comprise all forms of societal support for farmers’ climate risk management. This includes in particular arrangements of community-supported agriculture that reduce income risks for farmers, or payments for ecosystem services if their design takes risk into account. Formal, natural and social insurances may be substitutes or complements, and affect farmer behaviour in different ways. Thus, policy support for any of the three forms of insurance will have effects on the others, which need to be understood. InsuranceGrass takes an innovative interdisciplinary view and assesses formal, natural and social insurances: on how to cope best with impacts of climate extremes on grasslands, integrating social and natural sciences perspectives and feedbacks between them. Based on this holistic analysis, InsuranceGrass will provide recommendations for policy and insurance design to ensure effective risk-coping of farmers and to enhance sustainable grassland farming, considering economic, environmental and social aspects. Impacts of extreme and compound extreme events on the provision of ecosystem services (e.g. magnitude and quality of yield, climate regulation via carbon sequestration, plant diversity) by permanent grasslands in Germany and Switzerland are quantified based on long-term observations and field experiments. Cutting-edge model-based approaches will be based on behavioural theories and empirically calibrated. With the help of social-ecological modelling, InsuranceGrass explicitly incorporates feedbacks between farmers’ and households’ decision, grassland management options, and ecosystem service provision in a dynamic manner. The contributions of different insurance types are developed, discussed and evaluated jointly with different groups of stakeholders (i.e., farmers, insurance companies, public administration). A scientifically sound and holistic assessment of the role of formal, natural, and social insurances for the sustainability of grassland farming under extreme events requires both disciplinary excellence and seamless interdisciplinary collaboration. InsuranceGrass brings together four groups from Zürich and Leipzig, with unique disciplinary expertise and a track record of successful collaboration.

Untersuchungen zum universellen Skalenverhalten von Residualgasphasen mittels micro-Computer-Tomographie

Das Kapillare Einfangen von CO2-Gas und deren nachfolgende Auflösung sind zwei wichtige Speicherprozesse der CCS (Carbon Capture Storage)-Technologie, die im Rahmen des beantragtes Projektes untersucht werden sollen. Das zentrale Ziel ist ein Upscaling von porenskaligen Eigenschaften getrappter Gascluster mittels universellen Skalengesetzen, wie sie von der Perkolationstheorie vorhergesagt werden. Erstmals wird ein analytisches Näherungsverfahren zur Berechnung der effektiven Auflösungsrate angewendet und durch vergleichende Makroskala-Modellierungen (MIN3P und TOUGH2) getestet. Von grundlegendem Interesse ist die Frage, unter welchen Bedingungen, die im Projekt untersuchten porösen Medien zur gleichen Universalitätsklasse gehören, und welchen Einfluss, Porenstruktur, Mikrostruktur der Festkörperoberfläche und heterogene Benetzbarkeit auf den Trapping-Prozess haben. Methodisch wird mittels micro-Computertomographie und Bildanalyse sowohl die Porenstruktur, Porenraumtopologie und mittels Clusteranalyse die Geometrie und statische Verteilung getrappter Gascluster analysiert und quantifiziert. Die Dynamik des Trapping-Verhaltens wird mittels optischer Visualisierung in Glaskugel-Monolayer untersucht. Die Fluide werden so gewählt, dass sie Proxies für die CO2-Injektion in Tiefenaquifere darstellen. Die zu erwartenden Ergebnisse sind sowohl von grundlegendem Interesse als auch von großer praktischer Relevanz, da sie Prognose-Modellierungen zur CCS-Technologie und zur Grundwasserreinigung (Auflösung residualer NAPL (non aqueous phase liquid) bzw. von Mischgasphasen) verbessern.

Stabilization of organic matter by layer silikates - quality and turnover of interaction products

The overall goal of this proposal is to determine quantitative and qualitative relationships between carbon sequestration and clay mineralogy. The idea behind the project is that a extended period of fertilizer depletion combined with continued nutrient removal through plants will lead to changes in organic matter composition as well as to changes in the clay minerals assemblage (mainly through K-depletion in illitic materials). This in turn implies modifications in the physical properties as well as in the stability of the predominating clay-organic matter associations. We intend to investigate such changes on short, medium and long timescales. We will use experiments dating from 1902, 1956 and 1982. The overall goal will be devided in the following sub goals: a) which are the mechanisms behind the protective capacity of the mineral assemblage, b) what is the influence of clay mineralogy on stabilisation rates, c) how does the clay mineral assemblage influence proportion and type of organic matter associated with clay minerals, d) are there pathways from the pool of easily degradable organic matter into the pool of organic matter, that is stabilized through interaction with clay minerals, e) which rates of transfer are applicable here.
