From: Deep multi-task learning for early warnings of dust events implemented for the Middle East

The number of observed (rows) and predicted (columns) validation 3-hourly samples are presented. The rows and columns are ordered according to the local PM10 levels. Axes tick labels indicate the threshold bins that define these levels. Note that the two uppermost bins are above the threshold for dust events in this study.
