Eric Jenks MPO 551: HW #3, Problem 4 Infrared satellite utilizes the spectral window at a wavelength of 10.7 µm. At this wavelength, radiation emitted from Earth’s surface and from cloud tops move through cloud-free air with little-to-no absorption. The satellite looks at the intensity (or radiance) in this channel, and from the Planck function, you can determine the temperature of the surface from which the radiation is being emitted. The temperatures found by IR help determine where high clouds (seen in blue) are

Unformatted text preview: in relation to lower clouds (yellow and red). For weather forecasters, this can be helpful during severe weather events, as colder temperatures indicate higher clouds, which may be an indication of vertical growth in a thunderstorm. The case above shows a supercell in central Illinois (which produced a tornado on the ground at the time of the image)....
