June 2018 ASDC Newsletter Announcement

The ASDC June Newsletter introduces new product releases for AirMSPI's CalWater-2 flight campaign, CERES J01-FM6 Edition1-CV data for BDS, ES4, ES8 and ES9 products, and DSCOVR's EPIC L2 VESDR data product. MISR images for the Tinder Fire plume in Arizona and the Kilauea volcanic plume in Hawaii are highlighted, as well as the replacement of Surface meteorology and Solar Energy (SSE) with the Prediction Of Worldwide Energy Resources (POWER) site, and the upcoming FTP transition.

Ash from the Kilauea Eruption

Ash from the Kilauea Eruption On May 6, 2018, at approximately 11 a.m. local time, the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra satellite captured this view of the island as it passed overhead. Much of the island was shrouded by clouds, including the fissure on its eastern point. However, an eruption plume is visible streaming southwest over the ocean. The MISR instrument is unique in that it has nine cameras that view Earth at different angles: one pointing downward, four at various angles in the forward direction, and four in the backward direction. This image shows the view from one of MISR's forward-pointing cameras (60 degrees), which shows the plume more distinctly than the near-vertical views.

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.

Toolsets for Airborne Data

The Toolsets for Airborne Data (TAD), developed at the Atmospheric Science Data Center (ASDC) at NASA Langley Research Center (LaRC) to promote the airborne data use, has added additional data sets! Now available is the entire NASA Deriving Information on Surface Conditions from COlumn and VERtically Resolved Observations Relevant to Air Quality (DISCOVER-AQ) Campaign including Maryland, Texas, California, and Colorado. To order and download the aircraft data sets you can access TAD at: https://tad.larc.nasa.gov.

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.
