    • Volcanic Ash Advisory Database, 1983-2003

    Metadata Updated: October 18, 2024

    Volcanic ash is a significant hazard to aviation and can also affect global climate patterns. To ensure safe navigation and monitor possible climatic impact, the NOAA Satellite Services Division (SSD) tracks volcanic ash eruptions throughout the world. After an eruption, SSD issues a Volcanic Ash Advisory (VAA) message and a forecast of ash ___location in the atmosphere from the Volcanic Ash Forecast Transport and Dispersion (VAFTAD) model. The Volcanic Ash Advisory Database contains VAA messages, VAFTAD model output, and substantiating information from 1983 to 2003, that have been scanned into image format. The substantiating information includes surface weather observations, pilot reports, volcanic observatory reports, news media reports, and satellite imagery for each event. This database is static and is no longer being updated by NCEI.

    Lineage This database was started in 2004 when Grace Swanson of the NOAA/NESDIS/Satellite Analysis Branch provided twenty years (1983 to 2003) of files containing Volcanic Ash Advisory (VAA) messages issued by the Washington Volcanic Ash Advisory Center (VAAC), Volcanic Ash Forecast Transport and Dispersion (VAFTAD) model output, and substantiating information to the National Geophysical Data Center (NGDC) for archive and distribution. The documents were scanned into image format. The scanning effort was funded through the NOAA Earth Systems Data and Information Management (ESDIM) funding program. The purpose of the project was to provide examples to meteorological offices in other countries of the volcanic ash advisory decision-making process.
