Book Description
The first part of this book reviews the basics of atmospheric chemistry, radiation transport, and optical spectroscopy before detailing the principles underlying DOAS. The second part describes the design and application of DOAS instruments as well as the evaluation and interpretation of spectra. The recent expansion of DOAS application to the imaging of trace gas distributions by ground, aircraft, and satellite-based instruments is also covered.

Book Description
The field of optical and laser remote sensing has grown rapidly in recent years. This dynamic growth has been stimulated not only by technological advances in lasers, detectors, and optical system design, but also by the potential application of remote sensing systems to a wide variety of atmo spheric measurements. Optical and laser remote sensing can allow single ended measurement capability not offered by conventional point-detection techniques. While many past measurements have been associated with labo ratory research. practical systems have recently been developed which are capable of remotely detecting. measuring. and tracking a wide range of molecular and atomic species in the atmosphere with concentrations of parts per billion and at ranges over 100 km. This book is a compilation of papers which represent an overview of the present state of development of optical and laser remote sensing tech nology. The subjects covered include both passive and active remote sen sing techniques in the UV, visible, and IR spectral regions. related laser and detector technology, and atmospheric propagation and system analysis considerations. While the papers do not constitute an exhaustive treat ment of the excellent research being conducted in this field, they are representative of the wide diversity of present efforts. It is hoped that the reader will gain a general understanding of the current research in optical and laser remote sensing as well as an overview of current systems development.

Book Description
Almost all of the breakthroughs in understanding the atmospherehave been initiated by field observations, using a range ofinstrumental techniques. Developing or deploying instruments tomake further observations demands a thorough understanding of thechemical and spectroscopic principles on which such measurementsdepend. Written as an authoritative guide to the techniques of instrumentalmeasurement for the atmospheric scientist, research student orundergraduate, Analytical Techniques for Atmospheric Measurementfocuses on the instruments used to make real time measurements ofatmospheric gas and aerosol composition. Topics covered include howthey work, their strengths and weaknesses for a particular task,the platforms on which they have been deployed and how they arecalibrated. It explains the fundamental principles upon which theinstrumental techniques are based (ie what property of a moleculecan be exploited to enable its detection), what limits instrumentalsensitivity and accuracy, and the information that can be gainedfrom their use.

Book Description
The revised 2nd edition of this practical book provides an expanded treatment and comparison of techniques used in advanced optical measurements, guiding its reader from fundamental radiometric and photometric concepts to the state-of-the-art in highly sensitive measurements of optical losses and in spectroscopic detection using coherent laser light and spontaneous radiation. The book describes and compares a broad array of high-sensitivity methods and techniques – from interferometric and/or calorimetric, acousto-optic and resonator or polarization to wavelength- and frequency-modulation, phase-shift and decay time studies, and direct-loss measurements for free-space, fiber- or waveguide-based systems and devices. Updated throughout, the new edition describes novel trends in spectral interferometry, frequency-comb and laser-excitation spectroscopy, reflected in the developments of Raman, Brillouin and FTIR (Fourier Transform Infra-Red) techniques for biomedical research, biotech sensing and detection. It also covers broad practical implementations of time- and frequency-domain terahertz spectroscopy measurements. This book reviews the physical concepts of radiation transfer, providing a quantitative foundation for the means of measurements of optical losses, which affect propagation and distribution of light waves in various media and in diverse optical systems and components. It focuses on the application of optical methods and procedures for the evaluation of transparent, reflecting, scattering, absorbing, and aggregated objects, and for determining the power and energy parameters of radiation and color properties of light. This updated new edition will serve as an up-to-date reference source and practical guide for those using photometric and radiometric techniques.

Book Description
Applied Photometry, Radiometry, and Measurements of Optical Losses reviews and analyzes physical concepts of radiation transfer, providing quantitative foundation for the means of measurements of optical losses, which affect propagation and distribution of light waves in various media and in diverse optical systems and components. The comprehensive analysis of advanced methodologies for low-loss detection is outlined in comparison with the classic photometric and radiometric observations, having a broad range of techniques examined and summarized: from interferometric and calorimetric, resonator and polarization, phase-shift and ring-down decay, wavelength and frequency modulation to pulse separation and resonant, acousto-optic and emissive - subsequently compared to direct and balancing methods for studying free-space and polarization optics, fibers and waveguides. The material is focused on applying optical methods and procedures for evaluation of transparent, reflecting, scattering, absorbing, and aggregated objects, and for determination of power and energy parameters of radiation and color properties of light.
