This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Routine monitoring of fine aerosols in the Lake Tahoe basin began with the Tahoe Regional Planning Association (TRPA) in 1988 (Molenar et. al., 1994). During this time two sites of aerosol impact analysis were chosen based on prior work done by the ARB (Cahill et. al., 1997). These sites included Bliss SP, which is located near Emerald Bay at 200 m Lake Tahoe. Aerosols deposited at the Bliss SP site during each spring from 1988 to 2004, were predominately from sources outside of the Lake Tahoe basin and contained signatures from an "unknown north Sacramento Valley source" (Cahill and Cliff, 2002). The aerosols amounted to about 1/2 of all fine soil seen at South Lake Tahoe. With a better knowledge regarding the efficiency of the transport of fine aerosol plumes across the Pacific Ocean to North American combined with the presence of Asian dust signatures at other sites including Crater Lake and the Yukon, it was now determined that the source of fine particles to the Lake Tahoe basin was possibly Asian in origin. For this study, aerosols were collected during spring 2006, which coincides with the annual peak of Asian dust transport toward North America. Aerosols were collected at the TERC Tahoe Fish Hatchery, a relatively pollution free site northeast of Tahoe City. Aerosol collections at this site were done on an offshore pier, which reduced the amount of contamination for shore sources of aerosols and pollution such as road dust. The result was the identification of Asian dust signatures in aerosol deposition data for the period of April 28 to May 15, 2006. Such dust plumes were identified using HYSPLIT trajectories. Chemical signatures were also used including the Fe/Ca ratio, which is unique in Asian dust plumes. The particulate matter in these dust plumes produce a regional haze across the Lake Tahoe basin, which could impact incoming solar radiation. Furthermore, deposition of particles from the aerosol plume into the lake not only contributed to suspended particle concentrations there, but the particles themselves carried along with them a suite of bioactive nutrients including phosphorus. Phosphorus is of particular importance because of Lake Tahoe being a phosphorus-limited lake and atmospheric deposition of particles accounting for 26% of the phosphorus loading into the Tahoe basin. Aerosol optical depth data from the GOCART model and UV aerosol index data from the Earth Probe satellite identified additional aerosol deposition peaks of Asian origin particularly from the Gobi and Taklimakan deserts along with the Yellow River Basin near Beijing. Based on the GOCART and satellite data, aerosol dust deposition into the Lake Tahoe basin from Asian soils can be 1.31 times greater than those recorded in 2006 by the DRUM data. Such events had occurred in April 2001 and April 2005. The impact of climate variation on Asian dust transport toward Lake Tahoe was also analyzed primarily focusing on the impact of the Madden Julian Oscillation and shifts in the Aleutian Low on Asian dust transport. Based on these analyses, Asian dust transport is at its maximum when propagating MJO related convection is in the central Pacific Ocean and the Aleutian Low is over the Western Alaska. Both of these scenarios are associated with increased westerly wind flows and weaker high pressure off the West Coast of North America. This is instrumental is an efficient transport of dust plumes across the Pacific Ocean and further south toward California.

This book was released on 2008-09-30 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life on Earth is critically dependent upon the continuous cycling of water between oceans, continents and the atmosphere. Precipitation (including rain, snow, and hail) is the primary mechanism for transporting water from the atmosphere back to the Earth’s surface. It is also the key physical process that links aspects of climate, weather, and the global hydrological cycle. Changes in precipitation regimes and the frequency of extreme weather events, such as floods, droughts, severe ice/snow storms, monsoon fluctuations and hurricanes are of great potential importance to life on the planet. One of the factors that could contribute to precipitation modification is aerosol pollution from various sources such as urban air pollution and biomass burning. Natural and anthropogenic changes in atmospheric aerosols might have important implications for precipitation by influencing the hydrological cycle, which in turn could feed back to climate changes. From an Earth Science perspective, a key question is how changes expected in climate will translate into changes in the hydrological cycle, and what trends may be expected in the future. We require a much better understanding and hence predictive capability of the moisture and energy storages and exchanges among the Earth’s atmosphere, oceans, continents and biological systems. This book is a review of our knowledge of the relationship between aerosols and precipitation reaching the Earth's surface and it includes a list of recommendations that could help to advance our knowledge in this area.

Download or read book Atmospheric Aerosols written by Olivier Boucher and published by Springer. This book was released on 2015-05-18 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook aims to be a one stop shop for those interested in aerosols and their impact on the climate system. It starts with some fundamentals on atmospheric aerosols, atmospheric radiation and cloud physics, then goes into techniques used for in-situ and remote sensing measurements of aerosols, data assimilation, and discusses aerosol-radiation interactions, aerosol-cloud interactions and the multiple impacts of aerosols on the climate system. The book aims to engage those interested in aerosols and their impacts on the climate system: graduate and PhD students, but also post-doctorate fellows who are new to the field or would like to broaden their knowledge. The book includes exercises at the end of most chapters. Atmospheric aerosols are small (microscopic) particles in suspension in the atmosphere, which play multiple roles in the climate system. They interact with the energy budget through scattering and absorption of solar and terrestrial radiation. They also serve as cloud condensation and ice nuclei with impacts on the formation, evolution and properties of clouds. Finally aerosols also interact with some biogeochemical cycles. Anthropogenic emissions of aerosols are responsible for a cooling effect that has masked part of the warming due to the increased greenhouse effect since pre-industrial time. Natural aerosols also respond to climate changes as shown by observations of past climates and modelling of the future climate.
