CERES FM6 First Light Imagery

Clouds and the Earth's Radiant Energy System Flight Model 6 (CERES FM6) opened its cover on Jan. 5, 2018 allowing it to scan Earth for the first time. The instrument is one of five that launched Nov. 18, 2017 on the National Oceanic and Atmospheric Administration's (NOAA) Joint Polar Satellite System 1 (JPSS-1), and is the seventh and final copy since the first CERES instrument was launched in 1997. FM6 is the most accurate broadband radiometer that NASA/NOAA has flown that measures the solar energy reflected by Earth, heat the planet emits, and the role of clouds in that process.

MISR Aoba Volcano Plume

The Aoba volcano located on Ambae, one of the Vanuatu Island chain in the SW Pacific, began showing heightened activity on August 30, 2017. This image shows a Terra/MODIS image from Worldview taken March 16, 2018 of a Multi-Angle Imaging Spectroradiometer (MISR) observed plume reaching ~5km. Accurate plume heights are needed to determine the influence of volcanic eruptions, but are difficult to obtain due to the hazardous nature of volcanic eruptions. Stereo images from NASA's MISR make it possible to retrieve plume height in ongoing eruptions using  parallax.

Mt Agung (Bali) Eruption Plumes

Mt Agung (Bali) eruption plumes seen by MISR November 29, 2017   Volcanic eruptions can generate a significant amount of atmospheric aerosols that have regional to global impacts. Accurate plume heights are needed to determine the influence of volcanic eruptions, but are difficult to obtain due to the hazardous nature of eruptions. Stereo images from NASA’s Multi-Angle Imaging Spectroradiometer (MISR) make it possible to retrieve plume heights during eruptions.
