Download or read book Atmospheric Transmittance 7 30 Micrometers written by R. A. McClatchey and published by . This book was released on 1972 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: High resolution transmittance curves are presented for the spectral region 320-1400 wave numbers. These spectra are useful as a guide for selecting laser wavelengths for atmospheric propagation studies in this spectral region. In addition, this report provides specific information concerning the attenuation coefficients of 41 CO2 rotational laser lines in the 10.4 micrometer band system (v3 to v1). Charts for predicting the atmospheric attenuation of the CO2 laser lines are provided for each of five climatological model atmospheres and two haze models. The current report extends the work presented in two earlier reports on (1) CO laser attenuation in the 1400-2120/cm−1 (4.72-7. 14 micrometers) region: AFCRL-71-0370 and (2) HF and DF laser attenuation in the 2120-3740/cm (2.67-4.72 micrometers) region: AFCRL-72-0312. This report, when combined with the two previous reports described above, provides synthetic spectra for the entire region from 2.67-31.25 micrometers.

Download or read book Atmospheric Transmittance from 0 25 to 28 5 Micrometers written by J. E. A. Selby and published by . This book was released on 1976 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: This supplement provides several additions and updates to the LOWTRAN 3 computer code, which can be used to calculate the transmittance of the atmosphere from the ultraviolet to the middle infrared portion of the spectrum (0.25 to 28.5 micrometers) at a spectral resolution of 20 cm. The major additions are the inclusion of water vapor continuum attenuation in the 3.5 to 4.2 micrometers region, and a temperature dependence to the H2O continuum attenuation coefficient in both the 4 micrometers and 10 micrometers regions. The contribution of foreign gas broadening in the 8-14 micrometers region has also been reduced. Four aerosol models are included in this supplement. These include three boundary layer aerosol models for maritime, urban, and rural conditions in the lower 2 km of the atmosphere, and a tropospheric model for use mainly above 1 or 2 km altitude. The rural model is a replacement for the average continental model presently in LOWTRAN 3. A temporary provision is also given to accommodate fog conditions when the visual range falls below 2 km.

This book was released on 1974 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: High resolution atmospheric transmittance curves are presented for the spectral region 320 to 13,200/cm (0.7576 to 31.25 micrometers). These spectra are useful as a guide for selecting laser wavelengths for atmospheric propagation studies in this spectral region. In addition, this report provides attenuation coefficients for those lines of the CO, HF, DF, and CO2 laser systems which suffer the least atmospheric attenuation. A new aerosol model is introduced here, taking into account recent measurements of the complex index of refraction of aerosol particles. (Author).

Download or read book Fundamentals of Atmospheric Physics written by Murry L. Salby and published by Elsevier. This book was released on 1996-05-23 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Atmospheric Physics emphasizes the interrelationships of physical and dynamical meteorology. The text unifies four major subject areas: atmospheric thermodynamics, hydrostatic equilibrium and stability, atmospheric radiation and clouds, and atmospheric dynamics. These fundamental areas serve as cornerstones of modern atmospheric research on environmental issues like global change and ozone depletion. Physical concepts underlying these subject areas are developed from first principles, providing a self-contained text for students and scholars from diverse backgrounds. The presentation is Lagrangian (single-body problems) in perspective, with a balance of theory and application. Each chapter includes detailed and extensive problems; selected answers are provided, as are appendices of various constants. The text requires a thorough foundation in calculus. Presents a comprehensive introduction to atmospheric thermodynamics, hydrostatics, radiation and clouds, and dynamics Develops concepts from first principles, providing a self-contained volume for readers from diverse backgrounds Emphasizes the interaction of physical processes shaping global problems of atmospheric energetics, transport, and chemistry Provides a balance of theory and applications, with examples drawn from a wide range of phenomena figuring in global atmospheric research Extensively illustrated with global satellite imagery and analyses and photographs of laboratory simulations Exercises apply to a wide range of topical problems

Download or read book The Physics of Atmospheres written by John T. Houghton and published by CUP Archive. This book was released on 1977-05-26 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dr Houghton has revised the acclaimed first edition of The Physics of Atmospheres in order to bring this important textbook completely up-to-date. Several factors have led to vigorous growth in the atmospheric sciences, particularly the availability of powerful computers for detailed modelling, the investigation of the atmospheres of other planets, and techniques of remote sensing. The author describes the physical processes governing the structure and circulation of the atmosphere. Simple physical models are constructed by applying the principles of classical thermodynamics, radiative transfer and fluid mechanics, together with analytic and numerical techniques. These models are applied to real planetary atmospheres. This new edition is essential for undergraduates or graduate students studying atmospheric physics, climatology or meteorology, as well as planetary scientists with an interest in atmospheres.

Download or read book Comparison of Atmospheric Transmittance Measurements in the 3 5 Micrometers and 8 12 Micrometers Spectral Regions With MODTRAN Consideration for Long Path Geometries written by and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiance measurements conducted during tropospheric operations to detect objects on the Earth's surface from a manned aircraft or from an unmanned airborne vehicle (UAV) will involve long, near-horizontal viewing geometries. The computer code MODTRAN is widely used for the prediction of the propagation of infrared radiation through the lower atmosphere. This program was undertaken by the IARD to test and validate the predictions of the MODTRAN code for the 3-5 micrometer and 8-l2 micrometer spectral regions under semi-arid desert conditions with well defined meteorological parameters.
