This book was released on 1982 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors studied an analytical method to estimate chlorophyll and particle concentration in turbid water using MSS data collected after a heavy rain. The authors introduced the Multi Scattering Model into the analytical method. It was found that the analytical method employing the Multi Scattering Model was more effective than the method using statistical analysis which uses the relation between sea truth data and remote sensing data for estimating chlorophyll pigment concentrations. The method employing the Multi Scattering Model requires a number of sea truth data, but this number is less than the number required for the method employing the statistical analysis. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Light scattering-based methods are used to characterize small particles suspended in water in a wide range of disciplines ranging from oceanography, through medicine, to industry. The scope and accuracy of these methods steadily increases with the progress in light scattering research. This book focuses on the theoretical and experimental foundations of the study and modeling of light scattering by particles in water and critically evaluates the key constraints of light scattering models. It begins with a brief review of the relevant theoretical fundamentals of the interaction of light with condensed matter, followed by an extended discussion of the basic optical properties of pure water and seawater and the physical principles that explain them. The book continues with a discussion of key optical features of the pure water/seawater and the most common components of natural waters. In order to clarify and put in focus some of the basic physical principles and most important features of the experimental data on light scattering by particles in water, the authors employ simple models. The book concludes with extensive critical reviews of the experimental constraints of light scattering models: results of measurements of light scattering and of the key properties of the particles: size distribution, refractive index (composition), structure, and shape. These reviews guide the reader through literature scattered among more than 210 scientific journals and periodicals which represent a wide range of disciplines. A special emphasis is put on the methods of measuring both light scattering and the relevant properties of the particles, because principles of these methods may affect interpretation and applicability of the results. The book includes extensive guides to literature on light scattering data and instrumentation design, as well as on the data for size distributions, refractive indices, and shapes typical of particles in natural waters. It also features a comprehensive index, numerous cross-references, and a reference list with over 1370 entries.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The accurate characterization of fine suspended particles is central to a wide range of limnological research areas, including microbial ecosystem function and dynamics, underwater light propagation, nutrient cycling, and drinking water quality. The goal of this work was to develop methods to measure and characterize suspended particles in the oligotrophic Lake Tahoe, California-Nevada, where light scattering by particulates is the dominant process controlling lake clarity. Suspended particle populations were characterized using an in situ laser diffraction particle size analyzer--the LISST 100X. A set of laboratory tests was first performed to assess the accuracy of the LISST over a wide variety of environmental particle shapes and compositions. Processing techniques based on Mie theory were developed which enabled the LISST to produce accurate size distributions on the majority of the samples tested. Analysis of field data showed the LISST to be highly sensitive to ambient sunlight, causing erroneous spikes in small particle concentrations at high light levels. Techniques were developed to post-process the data and remove light contamination based on independently measured or modeled light intensities. These data processing techniques were employed to examine the composition of particulates in Lake Tahoe. Measured ratios of backscatter by particles to total particle scattering were used to estimate the bulk index of refraction, a proxy for particle composition. Sampling was performed during four periods relevant to the seasonal clarity cycle. Scattering ratios on all sampling days were found to be consistent with dominance by particles of predominantly organic composition. Consequently, the late spring minimum in Lake Tahoe clarity was shown to be likely due to phytoplankton growth stimulated by streamborne nutrients. Phytoplankton communities in the summer period of intense lake stratification were found to exhibit photoacclimation, the process by which algal cells adapt to lower light deeper in the water column by increasing their cellular chlorophyll concentration. These findings suggest a greater role of organic particles in impacting lake transparency than was previously thought, and have implications for lake clarity management.

This book was released on 2020-03-04 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth’s atmosphere and oceans play individual and interconnected roles in regulating climate and the hydrological system, supporting organisms and ecosystems, and contributing to the well-being of human communities and economies. Recognizing the importance of these two geophysical fluids, NASA designed the Plankton, Aerosol, Cloud and ocean Ecosystems (PACE) mission to bring cutting edge technology to space borne measurements of the atmosphere and ocean. PACE will carry the Ocean Color Instrument (OCI), a radiometer with hyperspectral capability from the ultraviolet through the near-infrared, plus eight discreet shortwave infrared bands. Thus, OCI will measure the broadest solar spectrum of any NASA instrument, to date. PACE’s second instrument will be a Multi-Angle Polarimeter (MAP). MAP will be NASA’s first imaging polarimeter on board a comprehensive Earth science mission. These instruments bring new capability to the science community, but also new challenges. Fundamentals, such as basic radiative transfer models, require review, enhancements and benchmarking in order to meet the needs of the atmosphereocean communities in the PACE era. Both OCI and MAP will bring opportunities to continue heritage climate data records of aerosols and clouds and to advance characterization of these atmospheric constituents with new macrophysical and microphysical parameters. The ability to better characterize atmospheric constituents is a necessity to better separate ocean and atmosphere signals in order to fully realize the potential of PACE measurements for oceanic observations. Atmospheric correction in the PACE era must address the expanded wavelength range and resolution of OCI images, requiring new approaches that go beyond heritage algorithms. This Research Topic encompasses fundamental radiative transfer studies, with application to the atmosphere, ocean or coupled atmosphere-ocean system. It includes remote sensing of aerosols, clouds and trace gases, over ocean or over land, but with particular focus on algorithms that take advantage of OCI’s new capabilities or multi-angle polarimetry. The Research Topic embraces studies of atmospheric correction over ocean including addressing issues of aerosols, cloud masking, foam, bubbles, ice etc., as well as ocean bio-optics and biogeochemical studies taking advantage of the PACE and polarization spectral capabilities.
