Book Description
SLICER data were acquired in support of BOREAS at all of the TF sites in the SSA and NSA, and along transects between the study areas. Data were acquired on 5 days between 18-Jul and 30-Jul-1996. Each coverage of a tower site is typically 40 km in length, with a minimum of 3 and a maximum of 10 lines across each tower oriented in a variety of azimuths. The SLICER data were acquired simultaneously with ASAS hyperspectral, multiview angle images. The SLICER Level 3 products consist of binary files for each flight line with a data record for each laser shot composed of 13 parameters and a 600-byte waveform that is the raw record of the backscatter laser energy reflected from Earth's surface. The SLICER data are stored in a combination of ASCII and binary data files.Hall, Forrest G. (Editor) and Nickeson, Jaime (Editor) and Harding, D. J. and Blair, J. B. and Rabine, D. L. and Still, K.

Book Description
The large-scale application of new silvicultural systems has become a political reality in many parts of the world. This involves a gradual transformation of traditional silvicultural practice towards Continuous Cover Forestry, also known as near-natural forest management, favouring mixed uneven-aged stands, site-adapted tree species and selective harvesting. Selective harvesting systems have a long tradition. Specific CCF-related resource assessment, forecasting and sustainable harvest control techniques have been developed, but details about their use are not widely known. The objective of this volume is to present state-of-the-art research results and techniques relating to CCF management with an emphasis on systems engineering and modelling. Using a very simple classification based on the development of timber volume over age or time we may distinguish two types of sustainable forest management systems. Rotation forest management (RFM) systems, characterized by standard silvicultural treatments and repetitive cycles of clearfelling followed by planting; and continuous cover forestry (CCF) systems which are characterized by selective harvesting and natural regeneration, resulting in uneven-aged structures and frequently also in multi-species forests. The distinction is usually the result of decisions relating to the cost of timber harvesting, simplicity of management, or various intangible benefits. The oldest and most perfect examples of CCF systems are the so called plenter selection forests found in France, Switzerland, Slowenia and Germany. Today, CCF systems are encountered in various regions of Europe, North America and in some tropical and sub-tropical forests of South Africa, Asia and South America.

Book Description
Although the majority of the world’s forest ecosystems are dominated by uneven-sized multi-species stands, forest management practice and theory has focused on the development of plantation monocultures to maximize the supply of timber at low cost. Societal expectations are changing, however, and uneven-aged multi-species ecosystems, selectively managed as Continuous Cover Forestry (CCF), are often believed to be superior to monocultures in addressing a wide range of expectations. This book presents methods which are relevant to CCF management and planning: analysing forest structures, silvicultural and planning, economic evaluation, based on examples in Europe, Asia, Africa and North and South America.

Book Description
The solar radiant energy is in fact the only source of energy for the basic physical processes taking place in the atmosphere and on the earth's surface. When passing through the atmosphere and being reflected by the ground surface, solar radiation undergoes changes and conversions. Some of it is absorbed in the atmosphere and converted into other forms of energy, mainly into heat, and some is scattered by gases, by dust and by water vapour. Because of absorption and scattering in the atmosphere, solar radiation is changed by the time it reaches the earth's surface. That part of it which arrives as a beam of parallel rays is referred to as direct solar radiation, and that which is scattered in the atmosphere and reaches the earth's surface from all directions of the sky is called diffuse solar radiation. Both of them are reflected back into the atmosphere when they reach the earth's surface, and this third type of radiation is defined as reflected radiation. All of these radiations differ from solar radiation arriving at the upper level of the atmosphere in intensity as well as in spectral composition although they all fall within the spectral region of solar radiation. In atmospheric physics these types of radiation are known as short-wave radiation (SWR) as distinguished from long-wave or irifrared radiation (L WR) emitted by the atmosphere and the earth's surface.

Book Description
Building on more than a decade of innovative research into multi-source forest inventory (MS-NFI) this book presents full details of the development, outputs and applications of the improved k-NN method. The method, which was pioneered in Finland in 1990, is rapidly becoming a world standard in forest inventory, having been adopted as standard in Finland and Sweden, and recently introduced in Austria and across the US. The book describes in detail the full MS-NFI process, and the input data used – including field data, satellite images, and digital map data, as well as coarse-scale variation of forest variables. It also presents comprehensive information on the types of outputs which can be derived, including maps and statistics, describing, for example, stock volumes and development, dominant tree species, age-class distribution, and large and small-scale variation. The book will provide an invaluable resource for those involved in forest inventory, including government departments and bodies involved in forest policy, management and monitoring, forest managers, and researchers and graduate students interested in forest inventory, modelling and analysis. It will find an additional market among those interested in Earth observation, ecology and broader areas of environmental and natural resource management. Erkki Tomppo was the winner of the 1997 Marcus Wallenberg Prize for his work on the k-NN method.

Book Description
The Alaskan Beaufort Sea: Ecosystems and Environments provides an interdisciplinary view into almost all aspects of the environment, with a detailed survey of the background literature. This book focuses on the Alaskan Beaufort Shelf environment. Organized into four parts encompassing 20 chapters, this book begins with an overview of the characteristics and history of the region in which the research took place and defines the objectives of the studies program. This text then examines the subsynoptic meteorological networks along the Beaufort Sea coast and shelf. Other chapters consider the thermally generated mesoscale effects on surface winds and the orographic mesoscale effects on surface winds. This book discusses as well the phytoplankton associations and relative phytoplankton production in the area between the 20-m depth contour and the edge of the ice in summer. The final chapter deals with the characteristics of the ice cover and oil-ice interactions that will affect cleanup activities after blowout. This book is a valuable resource for scientists and conservationists.
