The book describes the steps which lead from the raw signals measured in space to firstly calibrated an comparable long term data sets and in a second step to information for user communities. From the primarily spectral radiances information is inferred which is needed in the context of modeling climate variability such as the variable surface albedo and temperatures, soil moisture, and energy and water vapour fluxes between the surface and the atmosphere. This includes the assessment of medium scale land-surface changes like desertification and biomass productivity. Examples of applications and data validations result from different investigations in the Mediteranean area. An appendix summarizes useful formulas of the evaluation of satellite data. Beside the presentation of research results the book will therefore also be of interest for newcomers in the field and satellite data users who like to understand in greater detail the generation and information content of remote sensing data.

Mohamed Larbi Selassi Deputy Director of the National Meteorology, Morocco Welcome address (translated from French) WMO, WCRP, Medias-France and scientific institutions representatives, ladies and gentlemen, to thank WMO and MEDIAS-France, who have honoured us by I want first organizing the two workshops, climate indices in Africa and data assessment for global change research in the Mediterranean region, in Casablanca and I welcome all of you here in Morocco. It is with great pleasure that I open these two workshops on behalf of myself and on behalf of the Direction of the Meteorologie N ationale of Morocco. Climate change is becoming the focus of the international community because of its global scale and unpredictable effects, the numerous impacts it causes, its global feature and the complexity of the solutions that can mitigate its impacts. Global warming and the greenhouse effect became a subject of study at the international level since the United Nations Conference on the human environment that was held in Stockholm in 1972. The research and coordination efforts that have been made in this area have led to an "International Scientific consensus". High level meetings like those held in Toronto in 1988, in Lahaye in 1989 and in Geneva in 1990, did confirm the greenhouse threat and the emergency to treat it.

In zunehmendem Maße wird deutlich, daß Veränderungen in der Umwelt über komplexe Rückkoppelungen in alle Bereiche der menschlichen Existenz einwirken. Naturwissenschaftliche Feststellungen müssen daher von sozialwissenschaftlichen Analysen begleitet werden mit dem Ziel, Handlungsansätze für Politik, Wirtschaft und Gesellschaft zu erarbeiten. Das vorliegende Buch, von kompetenten Wissenschaftlern zusammengestellt, erlaubt dem Leser, die Bedeutung langfristiger Umweltveränderungen und Herausforderungen für die Zukunft zu erkennen.
