Wool s natural ability to absorb and transmit water vapor is of unique importance in maintaining Thermophysiological Comfort, a state in which the individual is free from thermal strain. The Humanitarian Blanket provides the necessary requirements for emergency and humanitarian relief situations.
Carbon 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. (Illustration NASA, Robert Rohde).nfrared 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.
