This book was released on 2010 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric aerosol particles were collected over three field experiments in the remote and coastal marine boundary layer of the eastern Pacific Ocean from aircraft, ship, and stationary platforms and were analyzed using Fourier Transform Infrared (FTIR) spectroscopy, Aerosol Mass Spectrometry (AMS), and Scanning Transmission X-ray Microscopy with Near-Edge Absorption Fine Structure (STXM-NEXAFS) for organic functional groups and organic mass fragments. X-ray fluorescence (XRF) and Scanning Electron Microscopy with Energy Dispersive X-rays (SEM-EDX) analyses were used to investigate the elemental composition of the analyzed particles. The aim of these studies was to better characterize particle sources and composition in the stratocumulus-topped marine boundary layer (MBL), where aerosol-cloud interactions play an important role in controlling the reflectivity of the large cloud decks. Particle composition was linked to distinct particle sources including primary marine emissions, biomass burning, and fossil fuel combustion. Fossil fuel combustion particles were characterized by large contributions from saturated alkane and carboxylic acid groups. Biomass burning aerosol particles were characterized as mixtures of alkane, carboxylic acid, and ketone groups, consistent with biogenic secondary organic aerosol particles observed in chamber studies. Photochemical aging of the transported smoke particles was observed on diurnal and multi-day timescales as an increase in the relative amount of oxygenated groups and oxygen-containing molecular fragments. Marine primary organic aerosol (POA) particles were observed in shipboard samples and were characterized by large contributions from organic hydroxyl groups, suggesting a carbohydrate-containing source in the ocean surface emitted during bubble bursting. Marine particles were also identified in single particle STXM-NEXAFS and were classified into four distinct categories including soluble and insoluble polysaccharides, proteins, and calcareous phytoplankton fragments. The presence of oxidized (polar) organic components--ketone, organic hydroxyl, and carboxylic acid groups--in submicron particles suggests that many of the measured particles could contribute to cloud condensation nuclei number concentration and mass in both open ocean and coastal regions. Together, these measurements show that marine POA provides a significant contribution to submicron particle mass in the clean MBL, whereas fossil fuel combustion and biomass burning emissions contribute the majority of the organic mass in coastal regions.

This book was released on 2020-12-03 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote Sensing is of paramount importance for Earth Observation to monitor and analyze the Earth’s vital signs. In this Special Issue are reported the latest research results involving active optical remote sensing instruments, both from ground-based to satellite platforms, that are involved in analyzing the vertical and horizontal aerosol and cloud distribution, other than their geometrical, optical and microphysical properties. Those active optical remote sensing techniques are also very useful in determining pollutant dispersion and the dynamics inside the boundary layer. The published studies put in evidence the hidden mechanisms on how pollution from the source is advected transnationally in other countries and the interaction with local meteorology.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 152. Sea salt aerosol (SSA) exerts a major influence over a broad reach of geophysics. It is important to the physics and chemistry of the marine atmosphere and to marine geochemistry and biogeochemistry generally. It affects visibility, remote sensing, atmospheric chemistry, and air quality. Sea salt aerosol particles interact with other atmospheric gaseous and aerosol constituents by acting as sinks for condensable gases and suppressing new particle formation, thus influencing the size distribution of these other aerosols and more broadly influencing the geochemical cycles of substances with which they interact. As the key aerosol constituent over much of Earth's surface at present, and all the more so in pre-industrial times, SSA is central to description of Earth's aerosol burden.

Available in PDF, EPUB and Kindle. Book excerpt: The book gives a comprehensive and lucid account of the science of the atmospheric boundary layer (ABL). There is an emphasis on the application of the ABL to numerical modelling of the climate. The book comprises nine chapters, several appendices (data tables, information sources, physical constants) and an extensive reference list. Chapter 1 serves as an introduction, with chapters 2 and 3 dealing with the development of mean and turbulence equations, and the many scaling laws and theories that are the cornerstone of any serious ABL treatment. Modelling of the ABL is crucially dependent for its realism on the surface boundary conditions, and chapters 4 and 5 deal with aerodynamic and energy considerations, with attention to both dry and wet land surfaces and sea. The structure of the clear-sky, thermally stratified ABL is treated in chapter 6, including the convective and stable cases over homogeneous land, the marine ABL and the internal boundary layer at the coastline. Chapter 7 then extends the discussion to the cloudy ABL. This is seen as particularly relevant, since the extensive stratocumulus regions over the subtropical oceans and stratus regions over the Arctic are now identified as key players in the climate system. Finally, chapters 8 and 9 bring much of the book's material together in a discussion of appropriate ABL and surface parameterization schemes in general circulation models of the atmosphere that are being used for climate simulation.

This book was released on 2017 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine boundary layer (MBL) clouds are an important, though uncertain, part of Earth's radiative budget. Previous studies have shown sources of aerosol particles in the remote MBL consist of primary sea spray, secondary organic and inorganic vapors derived from the ocean, entrainment from the free troposphere, and anthropogenic pollution. The potential for these particles to become cloud condensation nuclei (CCN) is largely dependent on their hygroscopic properties. Furthermore, when clouds form, physical processes can alter the optical properties of the cloud. This dissertation aims to identify variations in aerosol sources that affect MBL CCN concentrations and physical processes throughout the cloud lifetime that influence cloud optical properties. Ambient measurements of marine particles and clouds were made throughout two campaigns in the north Pacific and four campaigns in the north Atlantic. Both clean marine and polluted clouds were sampled. Dry MBL particles were measured to identify their chemical composition and size distribution, which is necessary to identify their potential to be CCN active. The organic hygroscopicity influenced CCN concentrations and cloud optical properties significantly for particles that were mostly organic, such as ship stack and generated smoke particles. For a typical range of organic hygroscopicity the amount of reflected solar radiation varied by 0.02-0.07 for polluted conditions and less than 0.01 for clean conditions (where 1.0 reflects all solar radiation). Simulated droplet spectral width was shown to be more representative of observations when using a weighted distribution of cloud base heights and updraft velocities, and increased the albedo up to 0.02. Cloud top entrainment and decoupling of the MBL were found to account for a decrease in cloud radiative forcing. Cloud top entrainment was corrected for homogeneous entrainment and accounted for a decrease in radiative forcing of up to 50 Wm-2. Clustering of individual marine aerosol particles resulted in the identification of particle types derived from dimethyl-sulfide (DMS) oxidation. Two particle types were identified to come from DMS oxidation products and accounted for approximately 25% and 65% of CCN at 0.1% supersaturation during the winter and summer, respectively.

Download or read book Investigating Marine Boundary Layer Aerosol Budgets and Variability written by Johannes Karel Christiaan Mohrmann and published by . This book was released on 2016 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine boundary layer (MBL) aerosol particles are an important feature of the climate system due in major part to their effect on marine boundary layer clouds, but the factors controlling their variability are not fully understood. A better understanding of the budget and controlling factors of these aerosol particles is needed to evaluate the effect of anthropogenic perturbations on aerosol concentrations and ultimately cloud radiative properties. Using data primarily collected during the MAGIC field campaign in the northeast Pacific, complemented by aerosol and meteorological reanalysis, we consider a simplified aerosol budget consisting of advection, precipitation loss, wind-mediated sea-surface generation, and entrainment from the lower free-troposphere. A major feature in MBL aerosol variability is the strong seasonal cycle, with concentrations observed to be approximately 50 cm−3 in winter and 100 cm−3 in the summer in the focus region (northeast Pacific). We explore seasonal differences in the concentration of accumulation mode aerosol particle number concentration using a steady-state model, which captures approximately two-thirds of the observed summer-winter difference. We find that precipitation differences account for approximately 53\% of the seasonal difference in aerosol particle concentrations, seasonal differences in advection account for 25%, and wind-driven surface sources and entrainment account for 18% and 4% respectively. Secondary particle formation and growth from smaller modes are not considered. The longitudinal gradient in aerosol particle number concentration is well-reproduced in summer, but overestimated in winter. Sensitivity analysis weighted by estimated variable uncertainty show that uncertainty in aerosol particle advection and free-tropospheric aerosol concentrations are the largest contributors to modeled aerosol uncertainty. On subseasonal timescales, high aerosol concentration events (in the top quartile of 6-hourly means) are found to correlate with shallow, non-precipitating boundary layers with high overlying aerosol concentrations, with no correlation with wind speed; this was observed in both summer and winter.

This book was released on 1996-05-01 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book recommends the initiation of an "integrated" research program to study the role of aerosols in the predicted global climate change. Current understanding suggest that, even now, aerosols, primarily from anthropogenic sources, may be reducing the rate of warming caused by greenhouse gas emissions. In addition to specific research recommendations, this book forcefully argues for two kinds of research program integration: integration of the individual laboratory, field, and theoretical research activities and an integrated management structure that involves all of the concerned federal agencies.
