Book Description
We developed a high resolution global coupled modeling capability to perform breakthrough studies of the regional climate change. The atmospheric component in our simulation uses a 1{sup o} latitude x 1.25{sup o} longitude grid which is the finest resolution ever used for the NCAR coupled climate model CCSM3. Substantial testing and slight retuning was required to get an acceptable control simulation. The major accomplishment is the validation of this new high resolution configuration of CCSM3. There are major improvements in our simulation of the surface wind stress and sea ice thickness distribution in the Arctic. Surface wind stress and ocean circulation in the Antarctic Circumpolar Current are also improved. Our results demonstrate that the FV version of the CCSM coupled model is a state of the art climate model whose simulation capabilities are in the class of those used for IPCC assessments. We have also provided 1000 years of model data to Scripps Institution of Oceanography to estimate the natural variability of stream flow in California. In the future, our global model simulations will provide boundary data to high-resolution mesoscale model that will be used at LLNL. The mesoscale model would dynamically downscale the GCM climate to regional scale on climate time scales.

Book Description
The proceedings of this workshop provide a valuable review of the methodologies of climate observations during the past 150 years, together with a summary of their findings, and a description of the difficulties inherent in their interpretation. In addition the volume reviews the use of climate model simulations of greenhouse-gas-induced equilibrium and nonequilibrium change. Finally, the contributed papers consider the methodologies of climate change detection by comparison of model simulations and climate observations, a summary of findings, and a description of what should be done to detect GHG-induced climate change. The volume will be of particular interest to researchers and students in the fields of meteorology, atmospheric science, oceanography, global change and climate impact assessement. Scientists in related fields will find much of value also.

Book Description
year simulations in order to separate noise in the system from the climate change signal. Several contributing papers focused on case studies using Regional Climate Models (RCMs) linked to hydrological models, applied to the analysis of runoff under conditions of convective activity and extreme precipitation, in regions of complex topography, or stakeholder-driven investigations such as water runoff simulations in Quebec undertaken for a major utility. Thorough analyses of GCM results for the Century were reported at the Workshop, in order to illustrate the improvements in model results which have taken place in recent years, and the increasing confidence with which the models can be used for projecting climatic change in coming decades. However, there is still much room for improvement; there is also a need to address more fully the manner in which climate and impacts models (e. g. , hydrological models) can be linked, in terms of consistency and the overlap between different scales, the underlying physical assumptions, and the parameterizations used. Session 2 was devoted to the two extremes of water resources, namely floods and droughts, the focus here being to identify the climate change component in river floods. These have significant economic implications, as was shown by several scientists from Western and Central Europe. Many long time series have been studied worldwide with the aim of detection of nonstationarities, yet there is no conclusive evidence of climate-related changes in flow records, in general.

Book Description
1 2 Michel M. VERSTRAETE and Martin BENISTON 1 Space Applications Institute, EC Joint Research Centre, Ispra, Italy 2 Department of Geography, University of Fribourg, Switzerland This volume contains the proceedings ofthe workshop entitled “Satellite Remote Sensing and Climate Simulations: Synergies and Limitations” that took place in Les Diablerets, Switzerland, September 20–24, 1999. This international scientific conference aimed at addressing the current and pot- tial role of satellite remote sensing in climate modeling, with a particular focus on land surface processes and atmospheric aerosol characterization. Global and regional circulation models incorporate our knowledge ofthe dynamics ofthe Earth's atmosphere. They are used to predict the evolution of the weather and climate. Mathematically, this system is represented by a set ofpartial differential equations whose solution requires initial and bo- dary conditions. Limitations in the accuracy and geographical distribution of these constraints, and intrinsic mathematical sensitivity to these conditions do not allow the identification of a unique solution (prediction). Additional observations on the climate system are thus used to constrain the forecasts of the mathematical model to remain close to the observed state ofthe system.

Book Description
The chapters in this book present state-of-the-art geomatics technologies applied in global environmental studies. This text provides the latest research findings and delivers complete references to related publications. This book will motivate the undergraduate and graduate students, researchers and practitioners to better understand the environmental changes with informed solutions. Global Change studies are increasingly considered a vital source of information to understand the Earth Environment, especially in the framework of human-induced, climate change and land use transformation. Satellite Earth Observing systems and geomatics technologies provide a unique tool to monitor and model the changes, respectively. While the range of applications and innovative techniques are always increasing, this book provides a summary of key study cases where satellite data offers critical information to understand the usefulness of the geomatics technologies and global environmental issues. Geomatics technologies provide powerful tools to model and analyze the effects of those global environmental changes towards minimizing their adverse impacts on human health and the environment.

Book Description
This research investigated the usage of different remote sensing techniques to determine land cover change, impacts of land cover change on summer climate of the Marmara Region, the utilization of Landsat images in regional climate modeling and the accuracy of global land cover data sets used in climate modeling. The Marmara Region, which experienced significant land cover changes as a result of rapid industrialization and population increase especially after 1980s, was selected as my study area. At the first stage of the research, Landsat MSS images obtained between 1972 and 1975 and Landsat ETM images obtained between 2001 and 2005 were used to derive multi-temporalland cover data of the Marmara Region. First, all images were atmospherically and radiometrically corrected to minimize contamination effects of atmospheric particles (scattering and absorption effects due to the atmosphere ) and systematic errors. Then, geometric correction was performed for each image to eliminate geometric distortions, correct errors in the relative positions of pixels, and defıne images in a common coordinate system. A new approach, semivariograms, was introduced to select appropriate band combinations for studying different land cover classes and determİne the regions having significant land cover changes. It was found that semivariograms can be used to determİne spatial variations and significantly changed areas can be identified using the changes in semivariogram parameters. Spatial profiles were created and examined to find out significant land cover changes in pilot regions and to determine the location and the size of land cover changes occurred in coastal zones. Based on the information obtained from semivariograms and spatial profiles, several pilot areas were created and classification employed separately for each area to minİmize the spectral mixing of various classes such as barren, crop and urban and increase the classification accuracy .The classification results were aggregated to 1 km and change detection.
