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. |
