Please choose a category. Mentel, and Defeng Zhao. Preprint under review for ACP discussion: open, 0 comments. Short summary. The oxidation of limonene, a common volatile emitted by trees and chemical products, by OH, a daytime oxidant, forms many highly oxygenated organic molecules HOMincluding C 10—20 compounds. HOM play an important role in new particle formation and growth.

HOM formation can be explained by chemistry of peroxy radicals and we found a minor branching ratio initial pathway play an unexpected and significant role. Joschka Pfeifer, Naser G. Umo, Dongyu S. Wang, Mingyi Wang, Stefan K. Manninen, Neil M. Donahue, Richard C. Attachment rate coefficients between ions and charged aerosol particles determine their lifetimes, and may also influence cloud dynamics and aerosol processing.

Here we present novel experiments that measure ion-aerosol attachment rate coefficients for multiply-charged aerosol particles under atmospheric conditions in the CERN CLOUD chamber. Our results provide experimental discrimination between various theoretical models.

Nadia Kathryn Colombi, Daniel J. Grange, Robert M. Yantosca, Soontae Kim, and Hong Liao. Surface ozone, detrimental to human and ecosystem health, is very high and increasing in South Korea.

Using a global model of the atmosphere, we found that emissions from South Korea and China contribute equally to the high ozone observed. We found that in the absence of all anthropogenic emissions over East Asia, ozone is still very high, implying that the air quality standard in South Korea is not practically achievable unless this background external to East Asia can be decreased.

This study details the first attempt with a GCM to simulate a fully prognostic aerosol species specifically for cirrus climate intervention. The new approach is in line with the real-world delivery mechanism via aircraft. However, to achieve an appreciable signal from seeding, smaller particles were needed, and their mass emissions needed to be scaled by at least a factor of На этой странице biases contributed to either overseeding, or small and insignificant effects in response to seeding cirrus.

Dickens, Zachariah W dka mistrall stratus feeder 3 60m free download, and Tsengel Nergui. Ozone is an air pollutant that is harmful to human health. Near the surface of Earth, ozone is created when other pollutants react in the presence of sunlight.

This study uses satellite data to investigate how ozone levels can be decreased in the Lake Michigan region of the United States. Our results indicate that ozone levels can be decreased by decreasing volatile organic compound emissions specifically in Chicago, Illinois, and decreasing nitrogen oxide emissions in the region as a whole.

Gabrielle R. Leung, Stephen M. Saleeby, G. Alexander Sokolowsky, Sean W. Freeman, and Susan C. This study explores how the concentration and type of aerosol particles impact shallow tropical clouds and the overall aerosol budget. Under more polluted conditions, there are more aerosol particles present, but we also find that clouds are less able to remove those aerosol particles via rainout. Instead, those aerosol particles are more likely to be detrained aloft and remain in the atmosphere for further aerosol-cloud interactions.

In the Marcellus, emissions were 3 times higher than the state inventory across the entire monitoring period. Tower observational networks can be utilized in other basins for long-term monitoring of emissions. Moore, and Helene Muri. Geoengineering indicates methods which aim to reduce the temperature of the planet by means of reflecting back a part of the incoming radiation before it reaches the surface, or allowing some more of the planetary radiation to escape to space.

GeoMIP aims to produce modelling experiments that are easy to reproduce and compare with different climate models, in order to understand the potential impacts of these techniques. W dka mistrall stratus feeder 3 60m free download we assess its past successes and failures, and talk about its future. Lhasa is the largest city on the Tibetan Plateau and its atmospheric mercury concentrations represent the highest level of pollution in this region.

Unexpectedly high concentrations of atmospheric mercury species were found. Combined with the trajectory w dka mistrall stratus feeder 3 60m free download, the high atmospheric mercury concentrations may have originated from external long-range transport.

Local sources, especially special mercury-related sources, are important factors influencing the variability of atmospheric mercury. Basic understandings of ozone processes, especially transport and chemistry, are essential to reduce ozone pollution, but studies often have different views on their relative importance. To explore the causes, we developed a tool based on the WRF-CMAQ modelling results to quantify their contributions in the ozone mass and concentration budgets, and w dka mistrall stratus feeder 3 60m free download that the difference between two budgets well explains these distinct views.

Future studies should be careful with budget-type selections. Laura Hyesung Yang, Daniel J. Jacob, Nadia K. Colombi, Shixian Zhai, Kelvin H. Yantosca, Haipeng Lin, Jared F. Brewer, Heesung Chong, Katherine R. Travis, James H. A geostationary satellite can now provide hourly NO 2 columns w dka mistrall stratus feeder 3 60m free download obtaining the NO 2 columns from space relies on NO 2 vertical distribution from the chemical transport model CTM.

Accurate fog forecast is difficult in a complex environment. Spatial variations in soil moisture could have impact on fog. Here we carried out fog simulations with spatially different soil moisture in complex topography. The soil moisture was calculated using satellite observations. The results show that the spatial variations in soil moisture do not have significant impact on where fog occurred, but do impact how long fog lasted. This finding could improve fog forecast in the future.

The biosphere flux at the provincial scale was re-estimated following the refined description in the regional inversion. W dka mistrall stratus feeder 3 60m free download, Douglas R. Worsnop, and Eleanor C. Ambient ion chemical composition measurements provide insight into trace gases that are precursors for the formation and growth of new aerosol particles.

We use a new data analysis approach to increase the chemical information from these measurements. Atmospheric mineral dust consists of tiny mineral particles that are emitted by wind erosion from arid regions. Nowadays, tecplot 10 for windows is an incomplete understanding of the emitted dust PSD and a lot of debate about its variability.

Here, we try to address these issues based on the measurements performed during a wind erosion and dust emission field campaign in the Moroccan Sahara within the framework of FRAGMENT project. Blake T. Sorenson, Jianglong Zhang, Jeffrey S. Reid, Peng Xian, and Shawn Jaker. We quality control OMI aerosol index data by identifying additional row anomaly and removing systematic biases, and further use the QA-ed data to quantify trends in UV приведенная ссылка aerosols over the Arctic region.

We found decreasing trends w dka mistrall stratus feeder 3 60m free download UV absorbing aerosols in spring months and increasing trends in summer months. For the first time, observational evidence of increasing trends in UV absorbing aerosols over the North Pole is found using the OMI data, especially over the last half decade. The study assesses to what extent the abatement of emissions in the rest of the world influences the exposure and mortality due to ozone and fine particulate matter in the region covered by the Gothenburg protocol mainly Europe and North America.

To that end, the impacts of pollutants deriving from different geographical areas and anthropogenic sources are analysed under a series of scenarios about the implementation of measures to abate air pollutants and greenhouse gas emissions.

We also showed that tropospheric ozone impacts определенно uk coin collector book free это the total column in the tropics. Preprint under review for ACP discussion: open, 1 comment. During March 12th to April 6th, in Beijing, there were 11 typical new particle formation days, 13 non-event days and 2 undefined days. We first analyzed the favorable background of new particle formation in Beijing, and then obtained the quantitative meteorological and solar radiation conditions of new particle formation.

In addition, we conducted the simulations using four nucleation schemes based on a global chemistry transport model GEOS-Chem to understand the nucleation mechanism. Several studies have noted that ozone in the lower part of the stratosphere ozone has not increased and perhaps even continued to decline in recent decades.

This study demonstrates that the amount of ozone in this region is highly sensitive to the amount of air upwelling into the stratosphere in the tropics, and that some climate models fail to accurately capture the variations in upwelling that control these short term trends in ozone. We demonstrated the development of high-resolution emission inventory and its application on evaluating the effectiveness of emission control actions, by incorporating the improved methodology, the best available data, and air quality modeling.

We show that substantial efforts on emission controls indeed played an important role on air quality improvement even with worsened meteorological conditions, and that the contributions of individual measures to emission reduction were greatly changing.

Chemical compositions variy between and within particles due to the complex sources and aging processes, causing particle-to-particle heterogeneity in aerosol hygroscopicity, which is of great importance to aerosol climatic and environmental effects. This study proposes an algorithm to w dka mistrall stratus feeder 3 60m free download the heterogeneity from in-situ measurements, providing a framework for жмите observation into numerical model to investigate how the heterogeneity influences aerosol impacts on climate and environment.

Chi Li, Randall V. Martin, Ronald C. Models are essential to diagnose the significant effects of nitrogen oxides NO x on air pollution. We use an air quality model to illustrate 1 the variability of NO x resolution-dependent simulation biases; 2 how these biases depend on specific chemical environments, driving mechanisms, and vertical variabilities; and 3 how these biases affect the interpretation of satellite observations.
