Book Description
The BOREAS TE-19 team developed a model called the Spruce and Moss Model (SPAM) designed to simulate the daily carbon balance of a black spruce/moss boreal forest ecosystem. It is driven by daily weather conditions, and consists of four components: (1) soil climate, (2) tree photosynthesis and respiration, (3) moss photosynthesis and respiration, and (4) litter decomposition and associated heterotrophic respiration. The model simulates tree gross and net photosynthesis, wood respiration, live root respiration, moss gross and net photosynthesis, and heterotrophic respiration (decomposition of root litter, young needle and moss litter, and humus). These values can be combined to generate predictions of total site net ecosystem exchange of carbon (NEE), total soil dark respiration (live roots + heterotrophs + live moss), spruce and moss net productivity, and net carbon accumulation in the soil. To date, simulations have been of the BOREAS NSA-OBS and SSA-OBS tower sites, from 1968-95 (except 1990-93). The files include source code and sample input and output files in ASCII format. The data files are available on a CD-ROM (see document number 20010000884), or from the Oak Ridge National Laboratory (ORNL) Distributed Activity Archive Center (DAAC).Hall, Forrest G.

Terrestrial Ecosystems in a Changing World
Author: Josep G. CanadellPublisher: Springer Science & Business Media
ISBN: 3540327304
Category : Science
Languages : en
Pages : 344
Book Description
This book examines the impacts of global change on terrestrial ecosystems. Emphasis is placed on impacts of atmospheric, climate and land use change, and the book discusses the future challenges and the scientific frameworks to address them. Finally, the book explores fundamental new research developments and the need for stronger integration of natural and human dimensions in addressing the challenge of global change.
Land Change Science
Author: Garik GutmanPublisher: Springer Science & Business Media
ISBN: 9400743068
Category : Business & Economics
Languages : en
Pages : 474
Book Description
This volume is a synthesis of the NASA funded work under the Land-Cover and Land-Use Change Program. Hundreds of scientists have worked for the past eight years to understand one of the most important forces that is changing our planet-human impacts on land cover, that is land use. Its contributions span the natural and the social sciences, and apply state-of-the-art techniques for understanding the earth: satellite remote sensing, geographic information systems, modeling, and advanced computing. It brings together detailed case studies, regional analyses, and globally scaled mapping efforts. This is the most organized effort made to understand the dominant force that has been responsible for changing the Earth’s biosphere. Audience: This publication will be of interest to students, scientists, and policy makers. This volume includes a CD-ROM containing full color images of a selection of illustrations which are printed in black-and-white in the book.
Terrestrial Magnetism and Atmospheric Electricity
Author: The Carbon Cycle
Author: T. M. L. WigleyPublisher: Cambridge University Press
ISBN: 9780521018623
Category : Science
Languages : en
Pages : 312
Book Description
Reducing carbon dioxide (CO2) emissions is imperative to stabilizing our future climate. Our ability to reduce these emissions combined with an understanding of how much fossil-fuel-derived CO2 the oceans and plants can absorb is central to mitigating climate change. In The Carbon Cycle, leading scientists examine how atmospheric carbon dioxide concentrations have changed in the past and how this may affect the concentrations in the future. They look at the carbon budget and the "missing sink" for carbon dioxide. They offer approaches to modeling the carbon cycle, providing mathematical tools for predicting future levels of carbon dioxide. This comprehensive text incorporates findings from the recent IPCC reports. New insights, and a convergence of ideas and views across several disciplines make this book an important contribution to the global change literature.

Biometeorology in Integrated Pest Management
Author: Jerry HatfieldPublisher: Elsevier
ISBN: 0323147968
Category : Technology & Engineering
Languages : en
Pages : 502
Book Description
Biometeorology in Integrated Pest Management is a resulting book from a conference with the same title held at the University of California in 1980. This book presents integrated pest management (IPM) in different viewpoints and perspectives. It serves as a helpful exchange of ideas to strengthen the research in integrated pest management. From a biometeorological viewpoint, the microclimate of agricultural systems is introduced in this book to describe the environment in which pests live. The first few chapters in this book discuss IPM in the perspective of biometeorology. Some of the topics include crop canopies (general heat exchange and wind movement), microclimate (instrumentation, techniques, and simulation), and microclimatic stress (remote sensing). The following section of the book focuses on plant pathology. The subject areas covered in this section include radiation quality and plant diseases; management of plant pathogens; and plant canopy modification and impact on plant disease. The last section focuses on weed science. The interaction of weeds to other pests, effects of light and temperature on weed growth, and weed seed germination are some of the topics discussed in this part. This book is a good source of reference to both students and professionals in the field of biometeorology, entomology, and agriculture. Other interested parties in the research of integrated pest management will also find this book helpful in their endeavors.
