Abstract

The Bureau of Meteorology issues volcanic ash advisories for the Darwin Volcanic Ash Advisory Centre (VAAC) area, which includes the active volcanic regions of Indonesia, PNG and the southern Philippines and extends to the South Pole. These advisories provide information on the erupting volcano, the observed ash cloud and the forecast for the ash cloud at +6, +12 and +18 hours. Ash clouds can have up to four height levels. The coding for ash height is given as SFC for surface and FL for flight line. The number after FL corresponds to units of 100 feet eg FL120 is a height of 12,000 feet. Individual advisories from the Darwin VAAC have been combined to create Web Map Service and Web Feature Service layers.

Data Quality

Scope:
Level: dataset
Lineage:
Statement: Volcanic Ash Advisories in a standard message format are produced by the Darwin VAAC when volcanic activity is observed. These text products are translated into SQL using a python script and imported into a Postgres/PostGIS database. Database tables include volcano position and ash cloud coordinates. All current advisories are grouped into two database views for generation of the Web Map Service and Web Feature Service.

Dataset Update Frequency

Maintenance And Update Frequency: continual
Maintenance Note: Products are produced for volcanic eruptions occurring within the Darwin VAAC area of responsibility.
