Available in PDF, EPUB and Kindle. Book excerpt: Wildland fires cause the loss of life and billions of dollars in property damage every year in the US annually; thus, there is a need to better understand, predict, and manage both wildland and prescribed fires. Moisture released from combustion, in addition to added heat, can enhance buoyancy and convection, influencing fire behavior. Previous studies have shown a wide range of smoke plume moisture enhancement, but much uncertainty still exists in the quantitative values of moisture released during combustion. In this study, three measurement platforms were used to obtain in situ measurements of temperature and relative humidity during various prescribed fires near the fire front and aloft. Stationary and non-stationary measurement platforms used were towers equipped with temperature and relative humidity probes, radiosondes, and a radio controlled (RC) airplane with a radiosonde installed in the wing. The goal of this study is to better quantify moisture of wildland fire smoke plumes. Water vapor concentration varied within the smoke plume from the surface and aloft. Water vapor captured by the radiosondes aloft was less than that obtained by the towers at the fire front, as a result of ambient air entraining into the smoke plume at higher levels. Tower and radiosonde results show smoke plume moisture enhancement ranged between 1.0 to 19.1 g kg-1 and 0.3 to 2.5 g kg-1, respectively. Smoke plume moisture enhancement captured by the RC airplane is on the order of 0.5 to 4.3 g kg-1, in agreement with the tower data from the same burn.

Book excerpt: Authored by world-class scientists and scholars, The Handbook of Natural Resources, Second Edition, is an excellent reference for understanding the consequences of changing natural resources to the degradation of ecological integrity and the sustainability of life. Based on the content of the bestselling and CHOICE-awarded Encyclopedia of Natural Resources, this new edition demonstrates the major challenges that the society is facing for the sustainability of all well-being on the planet Earth. The experience, evidence, methods, and models used in studying natural resources are presented in six stand-alone volumes, arranged along the main systems of land, water, and air. It reviews state-of-the-art knowledge, highlights advances made in different areas, and provides guidance for the appropriate use of remote sensing and geospatial data with field-based measurements in the study of natural resources. Volume 1, Terrestrial Ecosystems and Biodiversity, provides fundamental information on terrestrial ecosystems, approaches to monitoring, and impacts of climate change on natural vegetation and forests. New to this edition are discussions on biodiversity conservation, gross and net primary production, soil microbiology, land surface phenology, and decision support systems. This volume demonstrates the key processes, methods, and models used through many case studies from around the world. Written in an easy-to-reference manner, The Handbook of Natural Resources, Second Edition, as individual volumes or as a complete set, is an essential reading for anyone looking for a deeper understanding of the science and management of natural resources. Public and private libraries, educational and research institutions, scientists, scholars, and resource managers will benefit enormously from this set. Individual volumes and chapters can also be used in a wide variety of both graduate and undergraduate courses in environmental science and natural science at different levels and disciplines, such as biology, geography, earth system science, and ecology.

Download or read book Characterization of Smoke Plume Emissions and Dynamics from Prescribed and Wildland Fires Using High resolution Field Observations and a Coupled Fire atmosphere Model written by Kara M. Yedinak and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Smoke plumes associated with wildland fires are difficult to characterize due to the non-linear behavior of the variables involved. Plume chemistry is largely modeled using emission factors to represent the relative trace gas and aerosol species emitted. Plume dynamics are modeled based on assumptions of plume vertical distribution and atmospheric dispersion. In the studies presented here, near and in-source measurements of emissions from prescribed burns are used to characterize the variability of emission factors from low-intensity fires. Emissions factors were found to be in the same range as those from other, similar studies in the literature and it appears that the emission factors may be sensitive to small differences in surface conditions such as fuel moisture, surface wind speed, and the ratio of live to dead fuels. We also used two coupled fire atmosphere models, which utilize the Weather Research and Forecasting (WRF) model called WRF-Fire and WRF-Sfire, to investigate the role that atmospheric stability plays in influencing plume rise as well as developing a technique for assessing plume rise and the vertical distribution of pollutants in regional air quality models. Plume heights, as well as rate of growth of the fire, were found to be sensitive to atmospheric stability while fire rate of spread was not. The plume center-of-mass technique was demonstrated to work well but has slightly low estimates compared to observations.

Available in PDF, EPUB and Kindle. Book excerpt: Fire is rarely out of the headlines, from large natural wildfires raging across the Australian or Californian countrysides to the burning of buildings such as the disasters of Grenfell tower and Notre Dame. Fire on these scales can represent a serious risk to human life and property. But the advent of fire made and controlled by humans also represented a crucial point in our evolution, allowing us to cook our food, forge our weapons, and warm our homes. This Very Short Introduction covers the fundamentals of fire, whether wild or under human control, starting with the basics of ignition, combustion, and fuel. Andrew Scott considers both natural wildfires and the role of humans in making and suppressing fire. Despite frightening reports of wildfire destruction, he also shows how landscape fires have been part of our planet's history for 400 million years, and do not always have to be extinguished. He also considers the problem of fires in urban settings, including new ways to prevent fires. The cost of wildfire can be steep - as well as the burning, post-fire erosion and flooding can have a great impact on both humans and the environment. It can also have a lasting effect in shaping ecosystems and plant life. Scott ends by examining the relationship between fire and the climate, and considering the future of wildfire in a warming world. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Available in PDF, EPUB and Kindle. Book excerpt: In 1962 Rachel Carson warned of the consequences of man's pollution in her book Silent Spring, a book that some feel marks the real beginning of our environmental awareness. Silent Spring told of the consequences of our increasing pesticide use to birds. Almost 30 years after her warning, the western Arabian Gulf experienced its "silent spring" when approximately 100,000 to 250,000 waterbirds died, along with millions of other organisms, due to the massive oil spill that resulted due to Gulf war. The magnitude of our environmental problems has continued to grow during the last thirty years to a point where even the "doomsday" environmentalists could hardly have envisioned back in 1962. It seems the death of yet uncounted thousands of humans was not sufficient for Saddam Husain. His desire for power and infamy led him to unleash environmental war on mankind. At the end of the Gulf war he set ablaze the oil fields of Kuwait and released more oil into the sea than had been spilled at any time throughout history. These actions were despicable and an affront to civilized man. A quality environment should be a right of all mankind, and to wage war by deliberately polluting the earth cannot be tolerated.
