On Oct. 12, Ex-typhoon Halong hit AKs western coast, causing severe flooding in the Kuskokwim River Delta. VIIRS instruments captured the storm's trajectory in this animation using the longwave-IR band.

Satellites are always on the job, even while we’re sleeping! These #VIIRS products team up at night to give us a detailed look at fog in southeast Alaska. The DayNightBand is sensitive to visible light, like the moon, while the Nighttime Microphysics RGB can separate low clouds and fog.
