The National Aeronautics and Space Administration (NASA; /ˈnæsə/) is an independent agency of the U.S. federal government responsible for the civilian space program, as well as aeronautics and space research.[note 1] NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA). The new agency was to have a distinctly civilian orientation, encouraging peaceful applications in space science.[7][8][9] Since its establishment, most US space exploration efforts have been led by NASA, including the Apollo Moon landing missions, the Skylab space station, and later the Space Shuttle. NASA is supporting the International Space Station and is overseeing the development of the Orion spacecraft, the Space Launch System, Commercial Crew vehicles, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management for uncrewed NASA launches. NASA's science is focused on better understanding Earth through the Earth Observing System;[10] advancing heliophysics through the efforts of the Science Mission Directorate's Heliophysics Research Program;[11] exploring bodies throughout the Solar System with advanced robotic spacecraft such as New Horizons;[12] and researching astrophysics topics, such as the Big Bang, through the Great Observatories and associated programs.[13] Follow us on Twitter: https://twitter.com/BreakroomNachos Intro music by Dan Mason: https://danmason.bandcamp.com/

There are *billions* of dollars' worth of invaluable imagery, information, and data available, for free from NASA, NOAA, ESA, and more but unfortunately, sometimes it can be hard to get to… and hard to use. The folks at Element 84, a software development firm specializing in large scale geospatial data systems and remote sensing believe that the more they can help make that data accessible and usable, the more we can learn about our planet and how it's changing.    “How hard can it be?” is a question Dan Pilone often asks his team. As the CEO & CTO of Dan oversees the architecture, design, and development for Element 84's commercial and government data clients including NASA, USGS, Stanford University School of Medicine, and Capella Space. “   About Element 84  “We are impatient optimists.”  “It's not magic, but it can *feel* like that - you can literally *see* the world changing, see storms, progress of wildfires, patterns of burning and growth, how to plan for changing water levels, how to help people impacted by disasters, or even just see some fantastic images of leaves changing in the fall.... Space gives us an incredible view of the planet we live on- and we want as many people to be able to take advantage of that unique view as possible.” – Dan Pilone   More at: www.element84.com    Dan mentions:   FunCube: https://amsat-uk.org/funcube/funcube-cubesat/   More about Dan Pilone:   ​Dan has supported NASA's Earth Observing System for over 15 years; currently acting as Chief Technologist for the NASA EOSDIS Evolution and Development contract. He has supported transitioning NASA's Petabyte scale archive to the cloud, contributed to metadata standards, led multiple working groups on data services and cloud architectures, authored studies on architecture and transition plans for cloud-native data management solutions, and helped shape software development processes for both government and commercial clients. Mr. Pilone has authored multiple books on software development and taught Software Engineering at Catholic University in Washington DC.

Edward loves writing. His genre of writing is science fiction and techno thrillers. I asked Edward what is his "Why". He told me, "he can't sleep. He wakes up in the middle of the night with several topics in his head. He learned how to write in the dark and his wife is very happy of that lol. He sleeps with paper and pen next to his bedside." That tells me that Edward is so happy about his transition. ALL ABOUT EDWARD: Edward was a physicist and computer scientist. After thirty years in industry, working at every level from individual technical contributor to senior vice president, he is now writes full-time. Edward writes science fiction and techno-thrillers, now and again throwing in a straight science or technology article. Edward is an Author of the InterstellarNet series / Coauthor of the Fleet of Worlds series with Larry Niven. Young visions of becoming literally a rocket scientist morphed into a degree in physics. Mid-degree, he had an epiphany: he was good at physics but intuitive with computers. Physics was a terrific foundation for his newly chosen field—and later on, of course, for writing SF. Edward computer career began at Bell Labs, where his assignments dealt with telephone switching systems and design for ultra-reliability. Edward moved to Honeywell, entering engineering management and an evening MBA program. The work at Honeywell involved automated building controls, real-time systems for which my Bell Labs training was tremendously valuable. Suddenly, there was more time than he had in years for recreational reading. With more to read, he found much to criticize. His supportive wife, Ruth, eventually suggested that if he thought he could do better, he should. And so, circuitously, Edward began his writing career … Significant traces of his Bell Labs and Honeywell experience appear in my first novel, but what's most interesting in hindsight is how Probe foreshadowed his later career. By the time Probe appeared in print, he had changed employers, and his state of residence, twice. Edward was then newly arrived at Hughes Aircraft, one of a team chasing a large NASA contract. (They won.) While NASA personnel and settings play key roles in Probe, it was completed before his first NASA encounter. Edward never met any rocket scientists, but he did spend several fascinating years developing parts of the Earth Observing System. Edward got to know an astronaut. He even flew the shuttle training simulator twice, which was great fun. The downside of NASA contracting was its impact on his writing. Edward squeezed some time for some short stories, two of which appeared in Analog. As his engineering management career took off, there was little room for hobbies. On the plus side, the next several year in which few words of fiction were committed to electron produced a stockpile of source material for future stories. Edward eventually left Hughes to explore the alien worlds of start-ups and the Internet bubble. 1999 found Edward restless in his day job. A sabbatical spent writing recharged his batteries and produced a flurry of story sales (to Analog and Artemis). In 2001, it was back to engineering management. It turns out that the writing bug is persistent. After two more years in engineering and project management more telecom and government contracting work, Edward took the plunge into writing full time. For the next several years about half his writing was collaborative, from which the visible result is the five-novel Fleet of World series with Larry Niven. Larry is also done nonfiction, putting a straight-science slant on the research that underpins both completed & upcoming fiction.  Many of his nonfiction articles and essays are collected, updated, and expanded in Frontiers of Space, Time, and Thought: Essays and Stories on the Big Questions. The most recently (2018), Trope-ing the Light Fantastic: The Science Behind. You can go to the website at https://edwardmlerner.com/ or social media handles Edward M. Lerner

This lecture will provide an overview of atmospheric correction approaches for remote sensing of water properties for open oceans and coastal waters. Beginning with definitions of some basic parameters for describing ocean and atmosphere properties, the radiative transfer equation (RTE) for ocean‐atmosphere system will be introduced and discussed. Various methods for solving RTE, in particular, the successive‐order‐of‐scattering method will be described. We examine various radiance contribution terms in atmospheric correction, i.e., Rayleigh scattering radiance, aerosol radiance (including Rayleigh‐aerosol interaction), whitecap radiance, sun glint, and water‐leaving radiance. Atmospheric correction algorithms using the near‐infrared (NIR) and shortwave infrared (SWIR) bands will be described in detail, as well as some examples from MODIS‐Aqua measurements. The standard NIR atmospheric correction algorithm has been used for deriving accurate ocean color products over open oceans for various satellite ocean color sensors, e.g., OCTS, SeaWiFS, MODIS, MERIS, VIIRS, etc. Some specific issues of atmospheric correction algorithm over coastal and inland waters, e.g., highly turbid and complex waters, strongly absorbing aerosols, will also be discussed. The outline of the lectures is provided below.
