It provides volcanic activity monitoring along with creating and disseminating Volcanic Ash Advisories (VAA) and Volcanic Ash Graphics (VAG). The center's area of responsibility is the US including Hawaii, the Caribbean, Central America, northern South America, parts of the Pacific Ocean including the Marianas Islands. Data input for VAA and VAG include satellite imagery, model data, reports from State Volcano Observatories (SVO), Meteorological Watch Offices (MWO), many air traffic groups and others. Main users of VAA and VAG products include the aviation community including international and domestic airlines, air traffic control groups, the private sector, and scientific groups like the US Geological Survey (USGS). This collection of volcanic ash advisories and graphics is organized by each calendar year being contained within its own accession. Specifically: 2007 - accession 0298507 2008 - accession 0299273 2009 - accession 0299677 2010 - accession 0299771 2011 - accession 0299772 2012 - accession 0299770 2013 - accession 0299891 2014 - accession 0299890 2015 - accession 0299894 2016 - accession 0299893 2017 - accession 0299936 2018 - accession 0299938 2019 - accession 0299935 2020 - accession 0299940 2021 - accession 0299937 2022 - accession 0299939 2023 - accession 0301434 2024 - accession 0301435 2025 - accession 0311454 2026 - accession 0314611 This dataset is available to the public for a wide variety of uses including scientific research and analysis. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:OSPO-Washington-VAAC Preview graphic PNG 0298507 0299273 0299677 0299770 0299771 0299772 0299890 0299891 0299893 0299894 0299935 0299936 0299937 0299938 0299939 0299940 0301434 0301435 0311454 0314611 NCEI ACCESSION NUMBER 2026-04-30 publication Volcanic Activity theme NODC DATA TYPES THESAURUS meteorological model output pilot reports remote sensing satellite data visual observation theme NODC OBSERVATION TYPES THESAURUS Earth Observation Satellites Volcano Observatory weather stations platform NODC PLATFORM NAMES THESAURUS NOAA Office of Satellite and Product Operations dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS NOAA Office of Satellite and Product Operations dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS North Atlantic Ocean North Pacific Ocean South Atlantic Ocean South Pacific Ocean place NODC SEA AREA NAMES THESAURUS meteorology theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NESDIS/OSPO > Office of Satellite and Product Operations, NESDIS, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

NOAA National Centers for Environmental Information custodian Earth Observation Satellites Satellites that are specifically designed to observe Earth from orbit, similar to spy satellites but intended for non-military uses such as environmental monitoring, meteorology, map making etc. The most common type are Earth imaging satellites, that take satellite images, analogous to aerial photographs; some EO satellites may perform remote sensing without forming pictures, such as in GNSS radio occultation.

Volcano Observatory Volcano Observatory is a building, place, or institution designed and equipped for making observations on volcanoes. There are many such global volcano observatories. Reference: GCMD Keyword Finder weather stations Weather Stations are facilities or locations where meteorological data are gathered, recorded, and released. Such stations are of the first order when they make observations of all the important elements either hourly or by self-registering instruments; of the second order when only important observations are taken; of the third order when simpler work is done, as to record rainfall and maximum and minimum temperatures.
