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.

Available in PDF, EPUB and Kindle. Book excerpt: This report continues the development of a line-by-line radiative transfer code for inhomogeneous, spherical atmospheres with refractive bending. Optical path calculations and properties for standard atmospheres are combined with the radiative transfer processes to form an integrated program. The code is then modified to include non-LTE effects on radiance and transmittance at the higher altitudes. For accurate continuum absorption near band heads, a new sub- Lorentzian form factor is developed that is compatible with the codes algorithm for line modeling. The CO2 continuum is studied as a particular example. All new computer coding and theoretical developments are documented and supported with example calculations.

Download or read book Atmospheric Transmittance from 0 25 to 28 5 Um written by J. E. A. Selby and published by . This book was released on 1975 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: A FORTRAN computer program, LOWTRAN 3, is described for calculating the transmittance of the atmosphere in the spectral region from 0.25 to 28.5 micrometers at a spectral resolution of 20/cm. The program provides a choice of six atmospheric models covering seasonal and latitudinal variations from sea level to 100 km, two haze models, and accounts for molecular absorption, molecular scattering, and aerosol extinction. Refraction and earth curvature effects are also included. This program provides some modifications to the molecular absorption and aerosol extinction data provided in an earlier LOWTRAN 2 report. In addition, input modifications have been made, making the LOWTRAN 3 program considerably more flexible in terms of the input of meteorological data.

Download or read book Atmospheric Transmittance Radiance Computer Code LOWTRAN 6 Supplement Program Listings written by and published by . This book was released on 1983 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: This supplement lists the LOWTRAN 6 computer code for predicting atmospheric transmittance and the thermal radiation emitted by the atmosphere and earth from 350 to 40,000 per cm at a spectral resolution of 20 per cm. The program is based on the LOWTRAN 5 (1980) computer code. Solar/lunar scattered radiation has ben added to the code, as well as a new spherical refractive geometry subroutine and an improved water vapor continuum model. Other modifications to the code include a wind-dependent maritime aerosol model, a vertical structure aerosol model, a cirrus cloud model, and a rain model. The computer code contains representative (geographical and seasonal) atmospheric models and representative aerosol models with an option to replace them with user-derived or measured values. The program can be run in one of three modes, namely, to compute only atmospheric transmittance, to compute atmospheric transmittance and radiance, or to compute atmospheric transmittance, atmospheric radiance, and scattered solar/lunar background radiance for a given slant path geometry. Two new programs now available with the LOWTRAN 6 package, the plot program and the filter function program, are listed in this supplement.

This book was released on 2012-12-02 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectroscopy of the Earth's Atmosphere and Interstellar Medium focuses on the characteristics of the electromagnetic spectrum of the Earth's atmosphere in the far-infrared and microwave regions. It discusses the modes of observation in field measurements and reviews the two techniques used in the spectral region. Organized into six chapters, this volume begins with an overview of the effect of water-vapor absorption, followed by a discussion on the two frequently used method for deriving atmospheric parameters from high-resolution infrared atmospheric spectra, namely, the equivalent width (EW) technique and the nonlinear least-square fitting (NLSF). Other chapters consider the mechanisms by which interstellar clouds are formed. In addition, the book explores the composition of interstellar clouds, ion-molecule reactions, and the formation of stars. This book will be useful to anyone involved in, or interested in learning more about the field of atmospheric spectroscopy, including scientists, aeronomers, astronomers, astrophysicists, and students.
