Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on characterizing the emissions of volatile organic compounds (VOCs) from grasses and young trees, and the burning of biomass mainly from Africa and Indonesia. The measurements were performed with a proton-transfer-reaction mass spectrometer (PTR-MS). The biogenic emissions of tropical savanna vegetation were studied in Calabozo (Venezuela). Two field campaigns were carried out, the first during the wet season (1999) and the second during the dry season (2000). Three grass species were studied: T. plumosus, H. rufa and A. canescens, and the tree species B. crassifolia, C. americana and C. vitifolium. The emission rates were determined with a dynamic plant enclosure system. In general, the emissions increased exponentially with increasing temperature and solar radiation. Therefore, the emission rates showed high variability. Consequently, the data were normalized to a standard temperature of 30°C, and standard emission rates thus determined allowed for interspecific and seasonal comparisons. The range of average daytime (10:00-16:00) emission rates of total VOCs measured from green (mature and young) grasses was between 510-960 ngC/g/h. Methanol was the primary emission (140-360 ngC/g/h), followed by acetaldehyde, butene and butanol and acetone with emission rates between 70-200 ngC/g/h. The emissions of propene and methyl ethyl ketone (MEK) were

Book Synopsis Biology, Controls and Models of Tree Volatile Organic Compound Emissions by : Ülo Niinemets
Download or read book Biology, Controls and Models of Tree Volatile Organic Compound Emissions written by Ülo Niinemets and published by Springer Science & Business Media. This book was released on 2013-07-08 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-driven volatile organic compound (BVOC) emissions play a major role in atmospheric chemistry, including ozone and photochemical smog formation in the troposphere, and they extend the atmospheric lifetime of the key greenhouse gas, methane. Furthermore, condensation of photo-oxidation products of BVOCs leads to formation of secondary organic aerosols with profound implications for the earth's solar radiation budget and climate. Trees represent the plant life form that most contributes to BVOC emissions, which gives global forests a unique role in regulating atmospheric chemistry. Written by leading experts in the field, the focus is on recent advancements in understanding the controls on plant-driven BVOC emissions, including efforts to quantitatively predict emissions using computer models, particularly on elicitation of emissions under biotic and abiotic stresses, molecular mechanisms of volatile synthesis and emission and the role of emissions in plant stress tolerance.

Book Synopsis African Greenhouse Gas Emission Inventories and Mitigation Options: Forestry, Land-Use Change, and Agriculture by : John F. Fitzgerald
Download or read book African Greenhouse Gas Emission Inventories and Mitigation Options: Forestry, Land-Use Change, and Agriculture written by John F. Fitzgerald and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: As atmospheric concentrations of greenhouse gases continue to increase, so does the potential for atmospheric warming and associated climate change. In an effort to address the threat of global climate change, 155 countries signed the UN Framework Convention on Climate Change at the Earth Summit in Rio de Janeiro in June 1992. As of the first session of the Conference of the Parties, 128 nations had ratified the Convention. Among their other commitments, Parties to the Convention must develop and periodically update national inventories of net anthropogenic greenhouse gas emissions using comparable methodologies, and must develop and implement national programs to mitigate greenhouse gas emissions. To further the development of emission inventories and mitigation options within the African context, 64 governmental and non-governmental scientists and policy analysts from 23 nations gathered at a workshop near Johannesburg, South Africa from 29 May to 2 June 1995. The workshop focused on forestry, land-use change, and agriculture, because these sectors not only are responsible for the majority of emissions from the continent and provide promising opportunities for emissions mitigation, but also are a vital component of African economic growth and development. This book presents the workshop's major conclusions and findings, as well as individual papers that were prepared for the workshop, each of which was peer-reviewed and accepted for publication as part of the workshop process. The papers cover four areas: (1) issues are associated with data collection and emission factor determination; (2) problems associated with applying the IPCC inventory methodologies in Africa; (3) results of national inventory assessments in Africa; and (4) possible emissions mitigation options and methods for evaluating their potential viability. As the first book dedicated solely to greenhouse gas emissions and mitigation options in Africa, this will be an invaluable resource to scientists, policymakers, and development specialists interested in global climate change and Africa.

Download or read book Savanna Fire Emission Factors written by and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomass burning emission factors (BB EFs) exhibit significant variations across the savanna biome due to environmental conditions and fuel composition. Although we understand some factors contributing to this variability, quantifying their impact for integration into BB emission models has been limited by the absence of in situ EF measurements, especially concerning temporal dynamics. Traditional measurement methods are costly, time-consuming, and potentially biased toward either flaming (in airborne sampling) or smoldering (ground sampling) combustion products. To expand the spatiotemporal coverage of in situ measurements, we aimed to develop a versatile approach applicable to both prescribed and non-prescribed burns. We conducted four measurement campaigns in South Africa's Kruger National Park (KNP) and three in Brazil's Estação Ecológica Serra Geral do Tocantins (EESGT) to create a drone (UAS)-based sampling system and a measurement strategy for savanna landscape fires. In KNP, we compared UAS bag samples with continuous emission measurements from a passing fire front using a measurement mast. This confirmed the UAS's suitability for measuring fire-averaged trace gas EFs and hinted at the potential use of lightweight particle sensors for aerosol EF measurements, which led to laboratory fire experiments for aerosol equipment calibration. Beyond EF measurements, we utilized prescribed burning campaigns in KNP and EESGT to develop a method for mapping fuel load and burned area with a Micasense rededge multispectral camera. Subsequently, after developing and calibrating the EF measurement methodology, we captured the spatiotemporal variability of EFs and fuel conditions across the savanna biome. We targeted frequently burning vegetation types across a moisture availability gradient, conducting campaigns in both early dry season (EDS) and late dry season (LDS) for each vegetation type.

Book Synopsis Environmental Chemistry of Aerosols by : Ian Colbeck
Download or read book Environmental Chemistry of Aerosols written by Ian Colbeck and published by John Wiley & Sons. This book was released on 2008-03-24 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerosol particles are ubiquitous in the Earth’s atmosphere and are central to many environmental issues such as climate change, stratospheric ozone depletion and air quality. In urban environments, aerosol particles can affect human health through their inhalation. Atmospheric aerosols originate from naturally occurring processes, such as volcanic emissions, sea spray and mineral dust emissions, or from anthropogenic activity such as industry and combustion processes. Aerosols present pathways for reactions, transport, and deposition that would not occur in the gas phase alone. Understanding the ways in which aerosols behave, evolve, and exert these effects requires knowledge of their formation and removal mechanism, transport processes, as well as their physical and chemical characteristics. Motivated by climate change and adverse health effects of traffic-related air pollution, aerosol research has intensified over the past couple of decades, and recent scientific advances offer an improved understanding of the mechanisms and factors controlling the chemistry of atmospheric aerosols. Environmental Chemistry of Aerosols brings together the current state of knowledge of aerosol chemistry, with chapters written by international leaders in the field. It will serve as an authoritative and practical reference for scientists studying the Earth’s atmosphere and as an educational and training resource for both postgraduate students and professional atmospheric scientists.

Available in PDF, EPUB and Kindle. Book excerpt: In the context of Australia’s developing carbon economy, fire management helps to abate emissions of greenhouse gases and is an important means of generating carbon credits. The vast high-rainfall savannas of northern Australia are one of the world’s most flammable landscapes. Management of fires in this region has the potential to assist with meeting emissions reduction targets, as well as conserving biodiversity and providing employment for Indigenous people in remote parts of Australia’s north. This comprehensive volume brings together recent research from northern Australian savannas to provide an internationally relevant case study for applying greenhouse gas accounting methodologies to the practice of fire management. It provides scientific arguments for enlarging the area of fire-prone land managed for emissions abatement. The book also charts the progress towards development of a savanna fire bio-sequestration methodology. The future of integrated approaches to emissions abatement and bio-sequestration is also discussed.
Book Synopsis Volatile Organic Compounds in the Atmosphere by : Ralf Koppmann
Download or read book Volatile Organic Compounds in the Atmosphere written by Ralf Koppmann and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every day, large quantities of volatile organic compounds (VOCs) are emitted into the atmosphere from both anthropogenic and natural sources. The formation of gaseous and particulate secondary products caused by oxidation of VOCs is one of the largest unknowns in the quantitative prediction of the earth’s climate on a regional and global scale, and on the understanding of local air quality. To be able to model and control their impact, it is essential to understand the sources of VOCs, their distribution in the atmosphere and the chemical transformations which remove these compounds from the atmosphere. In recent years techniques for the analysis of organic compounds in the atmosphere have been developed to increase the spectrum of detectable compounds and their detection limits. New methods have been introduced to increase the time resolution of those measurements and to resolve more complex mixtures of organic compounds. Volatile Organic Compounds in the Atmosphere describes the current state of knowledge of the chemistry of VOCs as well as the methods and techniques to analyse gaseous and particulate organic compounds in the atmosphere. The aim is to provide an authoritative review to address the needs of both graduate students and active researchers in the field of atmospheric chemistry research.
