Short summary
Using 20 years of high-resolution satellite data, we present semi-quantitative evidence that High-Latitude Dust (HLD) sources to the atmosphere are widespread across the "Canadian Arctic Dust Belt". Our results also suggest that there is some increase in the frequency of dustiness with time, consistent with our understanding that HLD emissions are increasing in a warming climate.
