The near infrared absorption spectrum of liquid water at 20Â°C has been reinvestigated using a PbS cell detector system. The total spectral range investigated was from 0.70 to 2.50Î¼. A curve is included which shows five prominent absorption bands at 0.76, 0.97, 1.19, 1.45, and 1.94Î¼; and a table gives experimental results of water absorption at 20Â°C.
Infrared radiation is absorbed by greenhouse gases in the atmosphere. These gases also radiate energy, some of which is directed to the surface and lower atmosphere.arbon dioxide is not as strong a greenhouse gas as water vapor, but it absorbs energy in wavelengths (12-15 micrometers) that water vapor does not, partially closing the window through which heat radiated by the surface would normally escape to space.
