Question:

How is Landsat 8’s Cirrus band (Band 9) used?

Answer:

Landsat 8's Band 9 (1.360-1.390 µm) provides detection of high-altitude cloud contamination that may not be visible in other spectral bands.  

Cirrus clouds appear bright while most land surfaces will appear dark through cloud-free atmospheres containing water vapor.
