OSEI dust storm products include multichannel color composite imagery
and animations of meso- to large-scale dust storm events (DST). We also
create grayscale "split-window" images which use a channel differencing
technique that enhances the appearance of dust clouds in imagery (DIF).
This technique is often useful for distinguishing dust clouds from water
vapor clouds.
