Here is a video of our rainfall simulator in operation at our field site in the town of Orroli in Sardegna, Italy. I spent ten weeks in Sardegna during the summer of 2010 designing, constructing, and testing the rainfall simulator.  The password is "rain."

This is a video of the tipping bucket flow meter we constructed for the rainfall simulation system. We constructed it in the lab using the switch mechanism from a tipping bucket rain gauge.  The password is "rain."
