This figure is a simplified, schematic representation of the flows of <a href="//commons.wikimedia.org/wiki/Energy" class="mw-redirect" title="Energy">energy</a> between <a href="//commons.wikimedia.org/wiki/Space" class="mw-redirect" title="Space">space</a>, the <a href="https://en.wikipedia.org/wiki/Earth%27s_atmosphere" class="extiw" title="en:Earth's atmosphere">atmosphere</a>, and the <a href="https://en.wikipedia.org/wiki/Earth" class="extiw" title="en:Earth">Earth</a>'s surface, and shows how these flows combine to trap heat near the surface and create the <a href="https://en.wikipedia.org/wiki/greenhouse_effect" class="extiw" title="en:greenhouse effect">greenhouse effect</a>. Energy exchanges are expressed in <a href="https://en.wikipedia.org/wiki/watt" class="extiw" title="en:watt">watts</a> per square <a href="https://en.wikipedia.org/wiki/meter" class="extiw" title="en:meter">meter</a> (W/m<sup>2</sup>) and derived from Kiehl &amp; Trenberth (1997).
