Book Synopsis Air Mass Computer Program for Atmospheric Transmittance/radiance Calculation by : William O. Gallery
Download or read book Air Mass Computer Program for Atmospheric Transmittance/radiance Calculation written by William O. Gallery and published by . This book was released on 1983 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calculations of atmospheric transmittance and radiance require the knowledge of the integrated amounts of the absorbing gases along the path. This report describes the calculation of the integrated amounts ('air mass' or 'column density') for various infrared absorbing gases for an arbitrary slant path through the atmosphere, including the effects of both curvature and refraction, and presents a Fortran program. FSCATM, to perform the calculation. Among the features of FSCATM are: 1. It calculates the layer-by-layer integrated absorber amounts and density-weighted pressure and temperature for an arbitrary slant path through the atmosphere. 2. It assumes a spherically symmetric atmospheric with exponential profiles of density and refractivity between layer boundaries. 3. It allows a variety of options for specifying the slant path. 4. It includes six representative atmospheric profiles of pressure and temperature, and of density for the gases H2O, CO2, O3, N2O, CO, CH3, and O2 and has provision for user-supplied profiles of up to 20 gases. 5. The output layering may either be generated internally or supplied by the user. 6. It portable to 32 bit word computers in single precision and compatible with both ANSI Standard FORTRAN 66 and 77. 7. It is modular and easily modified to suit the users' particular needs. A discussion of atmospheric profile data and a survey of the literature are included in appendices.

Download or read book Middle Atmosphere Dynamics written by David G. Andrews and published by Academic Press. This book was released on 1987-09-11 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: For advanced undergraduate and beginning graduate students in atmospheric, oceanic, and climate science, Atmosphere, Ocean and Climate Dynamics is an introductory textbook on the circulations of the atmosphere and ocean and their interaction, with an emphasis on global scales. It will give students a good grasp of what the atmosphere and oceans look like on the large-scale and why they look that way. The role of the oceans in climate and paleoclimate is also discussed. The combination of observations, theory and accompanying illustrative laboratory experiments sets this text apart by making it accessible to students with no prior training in meteorology or oceanography.* Written at a mathematical level that is appealing for undergraduates andbeginning graduate students* Provides a useful educational tool through a combination of observations andlaboratory demonstrations which can be viewed over the web* Contains instructions on how to reproduce the simple but informativelaboratory experiments* Includes copious problems (with sample answers) to help students learn thematerial.
Book Synopsis Physics of Planetary Ionospheres by : S. J. Bauer
Download or read book Physics of Planetary Ionospheres written by S. J. Bauer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there are, in addition to the classic but somewhat dated books'l-, some excellent recent books on ionospheric physics and aeronomy'l-... , their scope is quite different from that of the present monograph. This monograph concentrates on the fundamental physical and chemical processes in an idealized planetary ionosphere as a general abstraction, with actual planetary ionospheres representing special cases. Such an approach appears most appropriate for a concise in troduction to the field, at a time when increasing experimental in formation on the ionospheres of other planets can be anticipated. The main purpose of this monograph, in line with that of the whole series, is to appraise where we stand, what we know and what we still need to know. It is mainly addressed to graduate students and researchers who are in the process of getting acquainted with the field. Within the scope of this monograph it would be impossible to do justice to all relevant publications. Hence, references are somewhat selective and largely limited to the more recent original papers and to authoritative reviews, the latter generally providing also detailed references regarding the historical development of the particular topic. Cgs (gaussian) units are generally used in this book, except where practical units are more appropriate. This book has evolved from a graduate course of the same title which I gave at the Catholic University of America, Washington, D. C.

Book Synopsis Aeronomy of the Middle Atmosphere by : Guy Brasseur
Download or read book Aeronomy of the Middle Atmosphere written by Guy Brasseur and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reader may be surprised to learn that the word "aeronomy" is not found in many of the standard dictionaries of the English language (for exam ple. Webster's International dictionary). Yet the term would appear to exist, as evidenced by the affiliations of the two authors of this volume (Institut d'Aeronomie, Brussels, Belgium; Aeronomy Laboratory, National Oceanic and Atmospheric Administration, Boulder, CO, USA). Perhaps part of this obscu rity arises because aeronomy is a relatively new and evolving field of endeavor, with a history dating back no farther than about 1940. The Chambers dic tionary of science and technology provides the following definition: "aeronomy (Meteor. ). The branch of science dealing with the atmosphere of the Earth and the other planets with reference to their chemical com position, physical properties, relative motion,
Book Synopsis A Critical Analysis of the Grad Approximation for Closing Out the Magnetohydrodynamic Equations for Plasmas by : Willard E. Meador
Download or read book A Critical Analysis of the Grad Approximation for Closing Out the Magnetohydrodynamic Equations for Plasmas written by Willard E. Meador and published by . This book was released on 1969 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A critical analysis is made of the utility of Grad's 13-moment distribution functions in closing out the generalized magnetohydrodynamic equations for plasmas. In particular, the inaccurate particle velocity dependence of the Grad approximation is shown to yield significant errors in the collisional transfers of such quantities as momentum and energy as functions of the moments (variables of the problem) considered. These errors directly affect the relations between moments which are derived by means of the aforementioned closing-out process; consequently, when the Grad functions are written so as to incorporate the moment relations, considerable doubt is cast upon the ability of such functions not only to describe the original 13 moments but also to predict accurately other plasma properties (e.g., the entropy) as well. Numerous comparisons with the exact first- and second-order perturbation solutions of the Boltzmann equation are made in order to substantiate these conclusions. A study also is made of the convergence of Grad-type functions as more moments are added, in consequence of which at least 16 moments are often necessary.

Available in PDF, EPUB and Kindle. Book excerpt: The reader may be surprised to learn that the word "aeronomy" is not found in many of the standard dictionaries of the English language (for exam ple, Webster's International dictionary). Yet the term would appear to exist, as evidenced by the affiliations of the two authors of this volume (Institut d' Aeronomie Spatiale, Brussels, Belgium; Aeronomy Laboratory, National Oceanic and Atmospheric Administration, Boulder, CO, USA). Perhaps part of this obscurity arises because aeronomy is a relatively new and evolving field of endeavor, with a history dating back no farther than about 1940. The Chambers dictionary of science and technology provides the following defini tion: "aeronomy (Meteor. ). The branch of science dealing with the atmo sphere of the Earth and the other planets with reference to their chemi cal composition, physical properties, relative motion, and reactions to radiation from outer space" This seems to us an appropriate description, and it is reflected throughout the content of this volume. The study of the aeronomy of the middle atmosphere experienced rapid growth and development during the 1970's and 1980's, particularly due to con cern over the possibility of anthropogenic perturbations to the state of the middle atmosphere and its protective ozone layer. As a result, much has been learned regarding both the natural behavior of the atmosphere and the impact of man's activities upon it. In this book we shall attempt to describe the current state of the art as we see it.
Book Synopsis A Computer Code for a One-dimensional Dynamic Model of the Mesosphere and Lower Thermosphere by : T. J. Keneshea
Download or read book A Computer Code for a One-dimensional Dynamic Model of the Mesosphere and Lower Thermosphere written by T. J. Keneshea and published by . This book was released on 1984 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: A one-dimensional computer simulation of the composition and the dynamics of the mesosphere and lower thermosphere between 50 and 400km is presented. The model is based on a numerical solution of large sets of partial differential equations for the conservation of mass and momentum for individual gases in an atmosphere with constant temperature and turbulent diffusion coefficient profiles. Incorporated into the model are 56 different neutral and ionic atmospheric species involved in 215 chemical and photochemical reactions. Distributions of many of the constituents are presented as determined from an application of the computer code to a midlatitude winter environment. Included are tables of the photodissociation rate coefficients as functions of the column densities of molecular oxygen and ozone for several of the atmospheric gases. Finally, the complete computer code is presented along with a detailed explanation of its structure and instructions for its use. Additional keywords: finite difference equations; equations of state.
