Volcanic Ash Advisory Database

Volcanoes Image

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.

The database contains over 37,000 images
