Book excerpt: We have conducted multi-year simulations describing the distributions of important chemical species in both the troposphere and stratosphere using the LLNL IMPACT atmospheric chemistry model. Simulations have been completed using input meteorological data from both a general circulation model (NCAR MACCM3, Middle Atmospheric Community Climate Model Version 3) and analyzed fields (NASA Data Assimilation Office, STRATF product). IMPACT includes modules describing tropospheric and stratospheric processes and emissions to determine species distributions from the surface to approximately 70 kilometers in altitude. We compare results of these simulations with both long term and short term observational data including surface measurements, vertical profiles and others. We contrast the model's ability to simulate important photochemical cycles (CO/CH4/NMHC/NOx/OH/O3, etc) using both input meteorological datasets. In addition, IMPACT simulations driven with analyzed data are compared to ground based and aircraft campaigns.

Download or read book Tropospheric Ozone and its Impacts on Crop Plants written by Supriya Tiwari and published by Springer. This book was released on 2018-03-07 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research and its outcomes presented here focuses on tropospheric or ground level ozone, in particular due to its surfacing as a major threat to crop productivity around the world. This book presents the ozone concentration data for a variety of geographical regions, examines the factors responsible for its increasing concentrations and its potential effects on physiological and biochemical responses culminating in crop productivity losses which, in turn may pose a serious threat to global food security. Beside this, certain ameliorative measures that could be adopted to assess ozone injury in plants are also discussed. Global climate change scenarios predict a significant increase in future tropospheric ozone concentration. Particular attention is therefore given to evaluate the effect of global climate change on ozone concentrations. Readers will also discover how yield losses due to ozone are related to changes in the socio-economic conditions of the society, especially in South Asian regions. Students and researchers studying crop and soil science, environmental scientists, risk assessment professionals and policy makers will find this book of interest.

This book was released on 1997-09-18 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: The end result of policy-related experimental and theoretical scientific work on the abatement of atmospheric emissions is a hierarchy of computer models that can be used to analyse and predict the behaviour of pollutants on urban, local regional and global scales. Such models are required to simulate an extremely complex natural situation in which a non-linear chemistry must be included together with the vagaries of the meteorology and the terrain. This book describes recent advances in the development and application of models on all scales, and in the techniques for the estimation and verification of emissions. It includes reviews of recent work together with detailed results and provides a useful picture of the field in a European context.

Download or read book Impacts of Aerosol cloud Interactions on Past and Future Changes in Tropospheric Composition written by and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of effective emissions control policies that are beneficial to both climate and air quality requires a detailed understanding of all the feedbacks in the atmospheric composition and climate system. We perform sensitivity studies with a global atmospheric composition-climate model to assess the impact of aerosols on tropospheric chemistry through their modification on clouds, aerosol-cloud interactions (ACI). The model includes coupling between both tropospheric gas-phase and aerosol chemistry and aerosols and liquid-phase clouds. We investigate past impacts from preindustrial (PI) to present day (PD) and future impacts from PD to 2050 (for the moderate IPCC A1B scenario) that embrace a wide spectrum of precursor emission changes and consequential ACI. The aerosol indirect effect (AIE) is estimated to be -2.0 Wm−2 for PD-PI and -0.6 Wm−2 for 2050-PD, at the high end of current estimates. Inclusion of ACI substantially impacts changes in global mean methane lifetime across both time periods, enhancing the past and future increases by 10% and 30%, respectively. In regions where pollution emissions increase, inclusion of ACI leads to 20% enhancements in in-cloud sulfate production and (almost equal to)10% enhancements in sulfate wet deposition that is displaced away from the immediate source regions. The enhanced in-cloud sulfate formation leads to larger increases in surface sulfate across polluted regions ((almost equal to)10-30%). Nitric acid wet deposition is dampened by 15-20% across the industrialized regions due to ACI allowing additional re-release of reactive nitrogen that contributes to 1-2 ppbv increases in surface ozone in outflow regions. Our model findings indicate that ACI must be considered in studies of methane trends and projections of future changes to particulate matter air quality.

This book was released on 2018-05-29 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the final report. The overall objective of this project is to improve the understanding of coupling processes among atmospheric chemistry, aerosol and climate, all important for quantitative assessments of global change. Among our priority are changes in ozone and stratospheric sulfate aerosol, with emphasis on how ozone in the lower stratosphere would respond to natural or anthropogenic changes. The work emphasizes two important aspects: (1) AER's continued participation in preparation of, and providing scientific input for, various scientific reports connected with assessment of stratospheric ozone and climate. These include participation in various model intercomparison exercises as well as preparation of national and international reports. and (2) Continued development of the AER three-wave interactive model to address how the transport circulation will change as ozone and the thermal properties of the atmosphere change, and assess how these new findings will affect our confidence in the ozone assessment results.Ko, Malcolm K.

This book was released on 2008-07-03 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stratospheric processes play a signi?cant role in regulating the weather and c- mate of the Earth system. Solar radiation, which is the primary source of energy for the tropospheric weather systems, is absorbed by ozone when it passes through the stratosphere, thereby modulating the solar-forcing energy reaching into the t- posphere. The concentrations of the radiatively sensitive greenhouse gases present in the lower atmosphere, such as water vapor, carbon dioxide, and ozone, control the radiation balance of the atmosphere by the two-way interaction between the stratosphere and troposphere. The stratosphere is the transition region which interacts with the weather s- tems in the lower atmosphere and the richly ionized upper atmosphere. Therefore, this part of the atmosphere provides a long list of challenging scienti?c problems of basic nature involving its thermal structure, energetics, composition, dynamics, chemistry, and modeling. The lower stratosphere is very much linked dynamically, radiatively,and chemically with the upper troposphere,even though the temperature characteristics of these regions are different. The stratosphere is a region of high stability, rich in ozone and poor in water - por and temperature increases with altitude. The lower stratospheric ozone absorbs the harmful ultraviolet (UV) radiation from the sun and protects life on the Earth. On the other hand, the troposphere has high concentrations of water vapor, is low in ozone, and temperature decreases with altitude. The convective activity is more in the troposphere than in the stratosphere.

Download or read book Hydrological Socioeconomic and Ecological Impacts of the North Atlantic Oscillation in the Mediterranean Region written by Sergio M. Vicente-Serrano and published by Springer Science & Business Media. This book was released on 2011-06-17 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mediterranean basin represents one of the most important “hot spots” of climate change in the world, with recent trends towards a hotter and drier climate being related to changes in atmospheric circulation patterns. Such changes can have significant impacts in the climate of this region but also on the natural environment and several socioeconomic activities. Among these patterns, the North Atlantic Oscillation (NAO) is one of the main forcing factors in the region with impact on extreme events such as droughts, severe precipitations or heat and cold waves, the availability of water resources, the ecological dynamics, the quality and quantity of crops, the migration and welfare of animal populations, the fisheries dynamics, the triggering of landslides and the air pollution and human health, among others. The aim of Hydrological, Socioeconomic and Ecological Impacts of the North Atlantic Oscillation in the Mediterranean Region, is to serve as an updated reference text that covers the wide range of evidences on the NAO impacts in the Mediterranean regions and from a multidisciplinary perspective. This volume constitutes a unique document to present the state of the art of the numerous studies undertaken on the hydrological, socioeconomic and ecological impact of the NAO, collecting the expertise of researchers from several complementary earth science fields (geography, hydrology, remote-sensing, climatology, agriculture, energy), but that have been lacking a common ground.
