Scientific paper

The spatial and temporal variability of dust emissions from different surfaces in the Lake Eyre Basin, Australia is determined using MODIS data. For 2003-6 the sources of 529 dust plumes were classified: overall 37% of plumes originated in areas of aeolian deposits, 30% from alluvial deposits and floodplains and 29% from ephemeral lakes or playas. At this sub-basin scale, the relative importance of different dust source geomorphologies varied primarily in response to sediment supply and availability and was not related to aeolian transport capacity, suggesting the Lake Eyre Basin is a supply-limited system.
