Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric aerosols play an important role in global atmospheric chemistry and climate and have a detrimental impact on human health. Advancements in measurement technologies allow for better monitoring of atmospheric composition and dynamics, creating better predictive models and understanding of atmospheric chemistry and physics. Gas and particle atmospheric oxidation is poorly understood. In order to create a better understanding of atmospheric oxidation, the following equipment was developed: 1) a Potential Aerosol Mass (PAM) flow reaction chamber was developed to create reproducible steady-state oxidation of organic species in a controlled laboratory setting, 2) a custom combustion chamber for introduction of realistic single source samples, and 3) a Thermal desorption Aerosol Gas chromatograph (TAG) for hourly speciation of hundreds of semi-volatile and non-volatile organic compounds. Development and construction of the Combustion Chamber, PAM Chamber, and TAG system are discussed as well as preliminary applications of this equipment. These instruments allow for the study of primary organic aerosol (POA) and secondary organic aerosol (SOA) formation. Due to the lack of knowledge concerning organic aerosol source chemical profiles and subsequent chemical evolution in the atmosphere, these studies are crucial for furthering the understanding of atmospheric chemistry and in developing accurate atmospheric models.

This book was released on 2017-01-29 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our world is changing at an accelerating rate. The global human population has grown from 6.1 billion to 7.1 billion in the last 15 years and is projected to reach 11.2 billion by the end of the century. The distribution of humans across the globe has also shifted, with more than 50 percent of the global population now living in urban areas, compared to 29 percent in 1950. Along with these trends, increasing energy demands, expanding industrial activities, and intensification of agricultural activities worldwide have in turn led to changes in emissions that have altered the composition of the atmosphere. These changes have led to major challenges for society, including deleterious impacts on climate, human and ecosystem health. Climate change is one of the greatest environmental challenges facing society today. Air pollution is a major threat to human health, as one out of eight deaths globally is caused by air pollution. And, future food production and global food security are vulnerable to both global change and air pollution. Atmospheric chemistry research is a key part of understanding and responding to these challenges. The Future of Atmospheric Chemistry Research: Remembering Yesterday, Understanding Today, Anticipating Tomorrow summarizes the rationale and need for supporting a comprehensive U.S. research program in atmospheric chemistry; comments on the broad trends in laboratory, field, satellite, and modeling studies of atmospheric chemistry; determines the priority areas of research for advancing the basic science of atmospheric chemistry; and identifies the highest priority needs for improvements in the research infrastructure to address those priority research topics. This report describes the scientific advances over the past decade in six core areas of atmospheric chemistry: emissions, chemical transformation, oxidants, atmospheric dynamics and circulation, aerosol particles and clouds, and biogeochemical cycles and deposition. This material was developed for the NSF's Atmospheric Chemistry Program; however, the findings will be of interest to other agencies and programs that support atmospheric chemistry research.

Download or read book Chemistry of the Upper and Lower Atmosphere written by Barbara J. Finlayson-Pitts and published by . This book was released on 2000 with total page 969 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here is the most comprehensive and up-to-date treatment of one of the hottest areas of chemical research. The treatment of fundamental kinetics and photochemistry will be highly useful to chemistry students and their instructors at the graduate level, as well as postdoctoral fellows entering this new, exciting, and well-funded field with a Ph.D. in a related discipline (e.g., analytical, organic, or physical chemistry, chemical physics, etc.). Chemistry of the Upper and Lower Atmosphere provides postgraduate researchers and teachers with a uniquely detailed, comprehensive, and authoritative resource. The text bridges the "gap" between the fundamental chemistry of the earth's atmosphere and "real world" examples of its application to the development of sound scientific risk assessments and associated risk management control strategies for both tropospheric and stratospheric pollutants. Key Features *Serves as a graduate textbook and "must have" reference for all atmospheric scientists * Provides more than 5000 references to the literature through the end of 1998 * Presents tables of new actinic flux data for the troposphere and stratospher (0-40km) * Summarizes kinetic and photochemical date for the troposphere and stratosphere *Features problems at the end of most chapters to enhance the book's use in teaching * Includes applications of the OZIPR box model with comprehensive chemistry for student use

This book was released on 2002-10-26 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This assessment of the technical quality and relevance of the programs of the Measurement and Standards Laboratories of the National Institute of Standards and Technology is the work of the 165 members of the National Research Council's (NRC's) Board on Assessment of NIST Programs and its panels. These individuals were chosen by the NRC for their technical expertise, their practical experience in running research programs, and their knowledge of industry's needs in basic measurements and standards. This assessment addresses the following: The technical merit of the laboratory programs relative to the state of the art worldwide; The effectiveness with which the laboratory programs are carried out and the results disseminated to their customers; The relevance of the laboratory programs to the needs of their customers; and The ability of the laboratories' facilities, equipment, and human resources to enable the laboratories to fulfill their mission and meet their customers' needs.
