1.37 µm - Cirrus Band - 2 km resolution - Band 4 will detect very thin cirrus clouds during the day. This band is centered in a strong water vapor absorption spectral region. It does not routinely sense the lower troposphere, where there is substantial water vapor, and thus provides excellent daytime sensitivity to high, very thin cirrus under most circumstances.

Band 4 is a visible channel and is therefore black during nighttime hours.
