The infrared water vapor channel is located at 6.7 microns where the earth's emitted spectrum is highly attenuated by water molecules. Thus, this channel senses radiation from the mid- and upper-levels of the atmosphere, from both water vapor and clouds. Because water vapor is transported by atmospheric circulations, it allows the detection of features in the mesoscale flow as well as hemispheric patterns.
