Data Assimilation : The Ensemble Kalman Filter
Data Assimilation comprehensively covers data assimilation and inverse methods, including both traditional state estimation and parameter estimation. This text and reference focuses on various popular data assimilation methods, such as weak and strong constraint variational methods and ensemble filters and smoothers. It is demonstrated how the different methods can be derived from a common theoretical basis, as well as how they differ and/or are related to each other, and which properties characterize them, using several examples.It presents the mathematical framework and derivations in a way which is common for any discipline where dynamics is merged with measurements. The mathematics level is modest, although it requires knowledge of basic spatial statistics, Bayesian statistics, and calculus of variations. Readers will also appreciate the introduction to the mathematical methods used and detailed derivations, which should be easy to follow, are given throughout the book. The codes used in several of the data assimilation experiments are available on a web page.The focus on ensemble methods, such as the ensemble Kalman filter and smoother, also makes it a solid reference to the derivation, implementation and application of such techniques. Much new material, in particular related to the formulation and solution of combined parameter and state estimation problems and the general properties of the ensemble algorithms, is available here for the first time.

Cross-border Governance and Sustainable Spatial Development : Mind the Gaps!
Border regions in Central Europe undergo tremendous changes due to the enlargement of the European Union and the related processes of Europeanization, bordering and re-bordering. The book explores the consequences of these processes for cross-border governance and spatial planning in Central Europe. It combines analyses of European and national framework conditions with case studies from border regions and cities in 8 countries. The focus is on generic questions of cross-border planning and cooperation as well as on selected sectors such as nature conservation, transport and economic development.
Coupled Models for the Hydrological Cycle : Integrating Atmosphere, Biosphere and Pedosphere
Hydrologists, climatologists, soil scientists and environmental engineers are frequently asked to analyse complex environmental problems. It is becoming increasingly apparent that these problems usually involve feedbacks between atmospheric, ecological, and hydrological systems, as well as human society. It is often the feedbacks between systems that are of greatest interest because they may produce unanticipated responses. That is why coupling of different compartments of the Earth system has emerged as a general challenge to the modelling community. This book considers an array of state-of-the-art coupling and modelling concepts. First the relevant Earth system cycles are presented, followed by a discussion on scale issues and multiple equilibria. Inter- and intra-compartmental coupling is addressed, along with a debate on non-linearities and questions of parameterisation. Several applications are presented, where a focus is on cases where the hydrological cycle plays a central role.
Counteracting Urban Heat Island Effects in a Global Climate Change Scenario
Urban Heat Islands (UHIs) are a microclimatic phenomenon which manifests as a significant increase in the temperature of cities compared to their surrounding areas. Recently the phenomenon has been enforced by the tendency to climate change and in particular by extreme climate events. This book presents and analyzes the results of a project to develop and apply mitigation and adaptation strategies and measures for counteracting the global urban heat islands phenomenon, supported by the EU’s Central Europe Regional Development Fund.
Costs of air pollution control : Analyses of emission control options for ozone abatement strategies
This work derives strategies for developing useful EU policies aimed at the control of air pollutants in Europe, especially ground-level ozone. The author starts with the air-pollution status quo in the late 1990s, placing further impacts of photooxidant concentrations into perspective. Emission sources are then analysed in detail, and a likely scenario for a business-as-usual development in emissions is proposed. From the cost-benefit perspective, it is shown that a holistic, integrated evaluation of all air pollutants and their effects results in a full accounting that reflects synergies and hidden benefits. The modelling scheme identifies emission targets needed to achieve compliance with EU thresholds, and calculations reveal the need to review established ozone thresholds and emission limits, even after discounting the positive effects of including central and eastern European nations.
Cost-Benefit Analysis of Environmental Goods by Applying Contingent Valuation Method : Some Japanese Case Studies
Contingent valuation is one of the means of incorporating socio-environmental considerations in cost–benefit analysis. The authors of this book have examined environmental valuation methods through the lens of cost–benefit analysis focused on three case studies in Japan: public parks, a bay wetland, and a recreational theme park. With implications for the world at large, the findings presented here serve as a valuable source of information on Japanese behavior regarding the valuation of environmental goods. New, alternative approaches and guidelines for cost–benefit analysis in the public and private spheres also are discussed. This volume makes an important addition to the library of all researchers and other scientists in the fields of environmental science and environmental economics.

Continental Scientific Drilling : A Decade of Progress, and Challenges for the Future
Scientific drilling is an indispensable tool of modern Earth science - search, as it provides the only means of obtaining direct information on processes operating at depth. Drilling allows for the determination of - situ properties of solid materials and fluids and permits testing of hypot- ses and models derived from surface observations. In addition, drill holes may be used as a natural laboratory for experiments and as observatories for long-term monitoring of on-going active processes. Earth drilling, therefore, plays a critical role in scientific research directed towards - proved understanding of the workings of our planet and has a key role in solving urgent socio-economic problems. As a rule, drilling projects are an integral component of major geosci- tific research programs, comprising comprehensive pre-site investigations, accompanying laboratory studies, the drilling phase itself, and consecutive measurements and tests in the drill hole. Such drilling programs are costly and thus only realizable to a limited extent. International cost sharing, the optimal utilization of all available resources, the incorporation of inter- tional leading experts, and the application of the existing know-how, as well as the selection of an optimal drilling location (“World Geological Site”), are thus essential elements of an international scientific drilling p- gram.

Congenital Diseases and the Environment
"In recent years, increasing attention and resources have been brought to bear on the relationship between the environment and congenital diseases. These diseases were previously thought to be mostly due to genetic causes. Even though the importance of genes as factors in causation is accepted, environmental factors seem to be implicated just as strongly. This book explores some further concepts that have arisen from more recent perceptions of environmental effects and their possible interactions with living systems. Discussion and presentation of old and novel ideas is targeted at developing a more holistic and united perception of the interaction between congenital diseases and the environment. Amongst the topics discussed are: -effects of prenatal exposure to toxic chemicals -intra-uterine exposure to drugs -effects of endocrine disrupters -environmental risk and sex ratio in newborns -surveillance of environmental impact-research and policy."
