Important GOES-East Channel Definition & Fire Weather Applications:
Visible:	Infrared (IR):	Water Vapor:
Band 1: Blue Band - Tuned to detect smoke and aerosols. Cloud characteristics will be masked somewhat. Band 2: Red Band - The classic visible satellite channel.	Band 3: Veggie (Near IR) - Burn scar detection. Band 7: (Shortwave IR) - Sensitive to extreme temperatures and is useful in hot spot detection (if there are not cloud or canopy obstructions). Band 13: Clean Longwave IR - Traditional infrared satellite data useful in determining cloud-top temperatures.	Band 8: Upper-Level Water Vapor - Tracking the upper-level jet stream & moisture. Band 9: Mid-Level Water Vapor - Tracking mid and upper-level moisture and jet streaks. Band 10: Low-Level Water Vapor - Tracking low-level moisture
