Tree Rings from IR melting

After an early spring snow storm, the skies cleared nicely the next day allowing full sunshine to hit these two evergreen trees near the Ames webcam. What happened during the day and shown in this lapse can be found in the radiation 101 book. The green tree absorbs incoming short wave radiation from the sun and then emitts it back to the snow surface as long wave radiation. The snow reflects the short wave and absorbs the long wave thus melting the snow around the tree near the long wave radiation source (the trees). This timelapse is taken from the Ames KCCI-TV SchoolNet8 Project webcam on 22 Mar 2006.
