The GOES-East weather satellite operated by the National Oceanic and Atmospheric Administration (NOAA) captured this awesome image below. This is the 6.2 µm - "Upper-level Water Vapor" Band with a 2 km resolution and is used for tropospheric water vapor tracking. A tutorial by CIMSS at the University of Wisconsin explains why the 6.2 micron channel is useful for detecting water vapor. He also compared the water vapor image with a shortwave IR image and the heat trail was apparent. This fact is important because it allows these types of weather satellites to "remain" over the same location.
