How do satellites make measurements
WebSatellites do not measure temperature directly. They measure radiances in various wavelength bands, which must then be mathematically inverted to obtain indirect … WebSatellites do not measure temperature in the same way that conventional thermometers do, namely by the temperature-dependent upward or downward movement of liquid (typically mercury or alcohol) in a narrow chamber, or the expansion or contraction of a coiled piece of metal. Instead, the microwave portion of the light spectrum is measured using ...
