My dust history

Understand long-term trends

Use the map to identify the dustiest, or least dusty, years on record, from 1960 to 2011. Compare the dust levels to the annual rainfall timeline. Use the knowledge to strengthen your wind erosion and ground cover management planning.

Information About

The dust history is a record of how dusty it's been in the last 50 years. The graph shows the total annual number of dust event days recorded for each year (1960-2011). A Dust Event Day (DED) is a day where at least 1 dust event was recorded. For each year, the total number of DEDs possible is 365 days, although nowhere in Australia is dust that much of a problem! When viewed together as a timeline, you can see which years recorded a lot of dust, and which years were least dusty.

Geographic markers

The geographic markers in the map are 'Stations'. These are meteorological (weather) stations operated by the Australian Bureau of Meteorology.

The NRM boundaries represent natural resource management regions as defined by the Australian Government, and further refined as per the report by Leys et al. 2009 "Improving the capacity to monitor wind erosion in Australia"

Data source

The data is sourced from Bureau of Meteorology records. Dust Event Days (DED) were calculated from the Bureau's visibility measurements and weather codes. Time period: 1960-2011.

About

We've categorised dust events into 4 classes in order of severity: Moderate Haze; Severe Haze; Moderate Dust Storm; Severe Dust Storm. The graph shows the proportion of dust events (No. events %) observed per year, in each category. You can see, each year, what the main type of dust event was (e.g. 60% of events were moderate hazes). When viewed together as a timeline, you can see how the main type of dust event may have changed over the years. We show data for the time period 1960 to 2011.
