            "title": "Landsat 9 Atmospheric Correction",
            "description": "Landsat collects light in visible and infrared wavelengths. Sunlight reflects off Earth’s surface, and scientists identify the land cover based on which wavelengths are reflected strongly or weakly.But sunlight is also reflected by particles in the atmosphere, which distorts the data and can lead to what looks like a haze in the imagery. Using basic principles of physics, and knowing the meteorological conditions, scientists can determine the effects of the scattering and absorption as light passes through the atmosphere. This atmospheric correction is essential to determining exactly how much of each wavelength reflected of the features of the surface, and having quantifiable data.The videos below show different examples of atmospheric scattering which need to be accounted for when doing atmospheric correction of satellite data. In these cases, it is for observations over water. The resulting atmospheric corrections are part of the process for the new Landsat Aquatic Reflectance data product. Landsat’s highly calibrated data products, free to download and use, are making detailed Earth-observation data more accessible to users and bringing a greater benefit to society. || ",

            "description": "From space, satellites including the NASA and U.S. Geological Survey’s (USGS) Landsat 8 can help scientists identify lakes where an algal bloom has formed. It’s a complicated data analysis process, but one that researchers are automating so resource managers around the country can use the satellite data to identify potential problems.Music: Light From Dark by Adam Salkedi, Neil Pollard [PRS], published by Atmosphere Music Ltd.; Experimental Design by Laurent Dury [SACEM], published by Koka Media; Against The Wall by Benjamin Peter McAvoy [PRS], published by Sound Pocket Music; Brainstorming by Laurent Dury[SACEM], published by Koka Media; Together As One by Le Fat Club [SACEM], Olivier Grim [SACEM]; published by Koka Media.Complete transcript available.Watch this video on the NASA Goddard YouTube channel. || 13800_aquatic_reflection_poster.png (1564x936) [2.7 MB] || 13800_aquatic_reflection_poster_print.jpg (1024x612) [237.1 KB] || 13800_aquatic_reflection_poster_searchweb.png (320x180) [130.5 KB] || 13800_aquatic_reflection_poster_thm.png (80x40) [10.8 KB] || 13800_aquatic_reflectance_prores.mov (1920x1080) [5.3 GB] || 13800_aquatic_reflectance_yt.mp4 (1920x1080) [632.1 MB] || 13800_aquatic_reflectance_fb.mp4 (1920x1080) [473.0 MB] || 13800_aquatic_reflectance_tw-720.mp4 (1280x720) [161.2 MB] || 13800_aquatic_reflectance_yt.webm (1920x1080) [21.7 MB] || 13800_aquatic_reflectance-captions.en_US.srt [9.4 KB] || 13800_aquatic_reflectance-captions.en_US.vtt [9.0 KB] || ",
