12.3 µm - "Dirty" Longwave IR Window Band - 2 km resolution - Band 15 at 12.3 µm offers nearly continuous monitoring for numerous applications, though usually through a split window difference with a cleaner window channel. These differences can better estimate low-level moisture, volcanic ash, airborne dust/sand, sea surface temperature, and cloud particle size.
