Wien's Displacement Law & Emission Spectra

  1. Apr 8, 2008 #1
    I have found several links using google to emission spectra of the Earth:

    http://lasp.colorado.edu/~bagenal/1010/SESSIONS/13.Light.html
    http://www.xylenepower.com/
    http://spaceguard.esa.int/NScience/neo/dictionary/emission.htm

    All of which indicate a temperature of 280K and peak clearly at around 18microns. However, Wien's displacement law indicates that the peak from thermal emission of the Earth should be at around 10 microns.

    Many of these websites are indeed specifically about Wien's law and yet these two values do not correlate at all. What is going on?
