8.4 µm - "Cloud-top Phase" Band - 2 km resolution - Band 11 is used in combination with the 11.2 and 12.3 µm bands to derive cloud phase and type products. This band is similar to the "traditional" IR longwave window band, although the 8.4 µm band assists in determining the microphysical properties of clouds.
