Wavelength and energy

Atmospheric transmission:
What causes the absorption bands in the UV, IR, and Microwave?
- electronic properties of molecules
- vibrational properties of molecules
- rotational properties of molecules

Emission:
Interactive program for drawing blackbody curves

GOES Imager   (GOES Project Science)

channel 1 visible                          0.52-0.72 micrometers, reflected sunlight

channel 2 short wave IR           3.78-4.03 micrometers, also called mid-wave IR, some reflected sunlight and some emitted radiation

channel 3 water vapor               6.47-7.02 micrometers, emitted radiation

channel 4 long wave IR            10.2-11.2 micrometers, emitted radiation

channel 5 split window IR        11.5-12.5 micrometers, emitted radiation

Why is the water vapor image only for the upper atmosphere?
Hint: the water vapor image is at 6.5-7.0 micrometers
