Book Description
An aerosol optical depth retrieval algorithm in the visible wavelengths for the NOAA POES AVHRR and GOES-8 visible imager is presented for the cloud free, marine atmosphere. The algorithm combines linearized single- scatter theory with an estimate of surface reflectance. Phase functions are parameterized using an aerosol size distribution model and the ratio of radiance values measured in channels 1 and 2 of the AVHRR. Retrieved satellite aerosol optical depth (AOD) is compared to three land-based sun photometer stations located on islands in the western Atlantic during July and September, 2001. GOES-8 channel 1 (visible wavelength) radiance values were initially calibrated using techniques developed by Rao. Additional connections to the channel 1 GOES- 8 radiances were made by applying a linear offset factor obtained during the experimental time period through comparison with AVHRR radiances. The results for the GOES -derived AOD compare favorably to the AERONET-measured AOD values. For both NOAA and GOES data, the comparison dataset has a correlation coefficient of 0.67 with a standard error of 0.07. For higher AOD cases (d = 0. 25), the general trend was for the satellite-derived AOD values to underestimate AERONET-observed conditions. During these higher conditions, the scattering phase function pattern contained within the algorithm deviated from the expected pattern, especially between 1400 1800. Overall, the more accurate calculations of AOD occurred over scatter angles between 140 deg - 150 deg and 170 deg - 180 deg.

GOES-8 channel 1 (visible wavelength) radiance values were initially calibrated using techniques developed by Rao and Zhang (1999). Additional corrections to the channel 1 GOES-8 radiances were made by applying a linear offset factor obtained during the experimental time period through comparison with AVHRR radiances. The results for the GOES-derived AOD compare favorably to the Aerosol Robotic NETwork (AERONET) AOD values. For both NOAA and GOES data, the comparison dataset has a correlation coefficient of 0.67 with a standard error of 0.7. During dusty conditions with corresponding higher AOD levels greater than or equal to 0.25, the general trend was for the satellite-derived AOD values to underestimate AERONET AOD values. Within these conditions, the scattering phase function pattern deviated from the expected pattern, especially between the scattering angles of 140 degrees to 180 degrees. Overall, the more accurate calculations of AOD occurred over scatter angles between 140 degrees to 150 degrees and 170 degrees to 180 degrees.

Book Description
The GOES-R Series: A New Generation of Geostationary Environmental Satellites introduces the reader to the most significant advance in weather technology in a generation. The world's new constellation of geostationary operational environmental satellites (GOES) are in the midst of a drastic revolution with their greatly improved capabilities that provide orders of magnitude improvements in spatial, temporal and spectral resolution. Never before have routine observations been possible over such a wide area. Imagine satellite images over the full disk every 10 or 15 minutes and monitoring of severe storms, cyclones, fires and volcanic eruptions on the scale of minutes. - Introduces the GOES-R Series, with chapters on each of its new products - Provides an overview of how to read new satellite images - Includes full-color images and online animations that demonstrate the power of this new technology

Book Description
The following listing represents a survey and a short description of 'Earth Observing Mis sions' in alphabetical order. The listing in Part A considers completed-, operational-as well as planned missions on an international scale (Earth observations from space know no na tional boundaries). A look into past activities is important for reasons of heritage, context and of perspective. The document is intended for all who want to keep track of missions and sensors in the fast -growing field of Earth observations. There cannot be any claim to com pleteness, although a considerable effort was made to collect and integrate all known mis sions and sensors into this book. Earth observation by remote sensing changes our view and perception of the world. We be gin to realize the global character of remote sensing, its multidimensional and complemen tary nature, its vast potential to many disciplines, its importance to mankind as a whole. Re mote sensing permits for the first time in history a total system view of the Earth. The view from space toward Earth has brought about sweeping revisions in the Earth sciences, in par ticular in such fields as meteorology, oceanology, hydrology, geology, geography, forestry, agriculture, geodynamics, solar-terrestrial interactions, and many others.

Book Description
America's unrestricted access to the Atlantic and Pacific Oceans, Gulf of Mexico, rivers, Great Lakes, and Arctic region powers domestic and global commerce. The ease of moving cargo and people beyond our coasts fuels the Nation's competitive advantage, advances trade, generates capital, and drives the domestic economy forward, in turn projecting strength abroad and safeguarding our national interests. Similarly, the biological diversity and productivity of the ocean sustains the health of coastal communities and promotes a vibrant national economy. The ocean also plays a fundamental role in the Earth system. Ensuring responsible ocean stewardship with science and technology (S&T) breakthroughs depends on a strategic Federal portfolio supported by foundational basic research. Science and Technology for America's Oceans: A Decadal Vision identifies pressing research needs and areas of opportunity within the ocean S&T enterprise for the decade 2018-2028.

Book Description
This book is the standard reference based on roughly 20 years of research on atmospheric rivers, emphasizing progress made on key research and applications questions and remaining knowledge gaps. The book presents the history of atmospheric-rivers research, the current state of scientific knowledge, tools, and policy-relevant (science-informed) problems that lend themselves to real-world application of the research—and how the topic fits into larger national and global contexts. This book is written by a global team of authors who have conducted and published the majority of critical research on atmospheric rivers over the past years. The book is intended to benefit practitioners in the fields of meteorology, hydrology and related disciplines, including students as well as senior researchers.
