Download or read book Tropospheric Processes Observations and Interpretation written by National Aeronautics and Space Adm Nasa and published by Independently Published. This book was released on 2018-10-18 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three aspects of tropospheric chemical processes imposed by manmade emission of source gases will be discussed. First, the implications for the OH distribution and thereby for the lifetime of source gases which are controlled by reactions with OH in the troposphere (e.g., CH4 and HCFC) are investigated. This is of importance for stratosphere ozone and climate. Second, we will study the impact of source gas emission on tropospheric ozone and discuss the possibility to estimate indirect climate effects from the changes in ozone and other climate gases. Finally, the degradation of HFC and HCFC's is discussed. Isaksen, Ivar S. A. and Fuglestvedt, J.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen oxides (NOx = NO + NO2) and ozone (O3) play important roles in the troposphere that impact air quality and climate. This thesis presents three projects that demonstrate how satellite observations interpreted with a chemical transport model can provide insight into emission, chemistry, and transport processes that affect NOx and O3 concentrations in the troposphere. Satellite observations from three instruments (MLS, OSIRIS, ACE-FTS) are used to reveal coherent patterns of low ozone events (

Book excerpt: Especially due to the increasing environmental problems there is a need to collect as many data as possible in the upper atmosphere. This book serves as a general multidisciplinary guide and introduction for a more effective use of the large amount of now available data from the Earth's atmosphere. It also shows the problems of the use of large amounts of time series data - for basic science as well as for environmental monitoring - and the related information systems. The book is aimed for scientists and students interested in the Earth's atmosphere which is vital for the understanding of environmental changes in the global system Earth.
Download or read book IMPACT a Coupled Tropospheric written by and published by . This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. 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 Modeling of Atmospheric Chemistry written by Guy P. Brasseur and published by Cambridge University Press. This book was released on 2017-05-04 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical modeling of atmospheric composition is a formidable scientific and computational challenge. This comprehensive presentation of the modeling methods used in atmospheric chemistry focuses on both theory and practice, from the fundamental principles behind models, through to their applications in interpreting observations. An encyclopaedic coverage of methods used in atmospheric modeling, including their advantages and disadvantages, makes this a one-stop resource with a large scope. Particular emphasis is given to the mathematical formulation of chemical, radiative, and aerosol processes; advection and turbulent transport; emission and deposition processes; as well as major chapters on model evaluation and inverse modeling. The modeling of atmospheric chemistry is an intrinsically interdisciplinary endeavour, bringing together meteorology, radiative transfer, physical chemistry and biogeochemistry, making the book of value to a broad readership. Introductory chapters and a review of the relevant mathematics make this book instantly accessible to graduate students and researchers in the atmospheric sciences.

Download or read book Rainfall Observations and Modelling written by Lakshmi Kumar TV and published by BoD – Books on Demand. This book was released on 2024-06-12 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides chapters with subjects ranging from the basic understanding of rainfall variability to the impact of climate change with novel methodologies and concepts. This book is mainly intended for post-graduate doctoral students and early career researchers for their use in academic and research programs. This book compiles the chapters with different data sets that are publicly available and from site-based measurements along with the data generation methods and modeling aspects. Rainfall plays an important role; its deficiency leads to meteorological droughts and further impacts hydrological, agricultural, and socioeconomic droughts, and its surplus causes floods over urban areas. With the advancement of technology, it is possible to determine future rainfall accurately by collating the data from observations, radar, and satellite and model simulations. The current book is of immense help in evaluating and understanding the atmospheric processes governed by the various physical laws, and the results of the chapters provide deep insight for a better understanding of rainfall phenomena across the different regions of the world.

This book was released on 2020-09-29 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the author’s research resulted in developing the satellite radiothermovision approach which allows retrieving dynamical and energy characteristics of atmospheric mesoscale and synoptic-scale processes based on a close scheme of satellite passive radiometry data processing. The book introduces new applications of the satellite passive microwave observations to detailed systematic study of tropical cyclones’ evolution, climatology and characteristics of atmospheric river, parameters of global atmospheric circulation and their variations on climatically significant scales. The results presented in the book demonstrate a clear relation between the convergence/divergence of latent heat from the lower atmosphere to the center of tropical cyclone with variations of its intensity and provide a better insight into the tropical cyclone dynamical energy balance based on remote data.

This book was released on 2019-01-03 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improved observations of the atmospheric boundary layer (BL) and its interactions with the ocean, land, and ice surfaces have great potential to advance science on a number of fronts, from improving forecasts of severe storms and air quality to constraining estimates of trace gas emissions and transport. Understanding the BL is a crucial component of model advancements, and increased societal demands for extended weather impact forecasts (from hours to months and beyond) highlight the need to advance Earth system modeling and prediction. New observing technologies and approaches (including in situ and ground-based, airborne, and satellite remote sensing) have the potential to radically increase the density of observations and allow new types of variables to be measured within the BL, which will have broad scientific and societal benefits. In October 2017, the National Academies of Sciences, Engineering, and Medicine convened a workshop to explore the future of BL observations and their role in improving modeling and forecasting capabilities. Workshop participants discussed the science and applications drivers for BL observation, emerging technology to improve observation capabilities, and strategies for the future. This publication summarizes presentations and discussions from the workshop.
