    How are the satellites that detect water vapor made? What goes into them that allow companies such as NOAA to create those water vapor images?

    NOAA (National Oceanic and Atmospheric Administration, to give it its proper name), is an agency of the US government, not a private company.

    Satellites are just the vehicles which carry the sensors into orbit. Microwave radiation from the atmosphere is used to estimate the amount of water vapor.

    The satellites have instruments to detect many different portions of the EM spectrum. Water vapour is often detected in the 5 - 8μm range.
