OSEI volcano products include multichannel color composite imagery showing ash clouds (VSH), hotspots from lava flow (VIR) or both (VOL). We also create grayscale "split-window" images which use a channel differencing technique that enhances the appearance of ash clouds in imagery (DIF). This technique is oftenuseful for distinguishing ash clouds from water vapor clouds.

The Washington Volcanic Ash Advisory Center has real time satellite imagery and derived advisory products at:
