The cloud reduction experiment consists of two plots. One control and one treatment. The treatment plot consists of a 30m high and 40m wide vertical panel of fine plastic mesh which has been suspended between two towers and extends ~10 m above the plant canopy down to ground level. The panel is angled perpendicular to the predominant wind direction to intercept airborne water particles moving up a forested valley thereby reducing cloud water inputs to the experimental forest plot behind the curtain. In addition, mesh panels are erected along the up-slope sides of the experimental plot, minimizing the possibility for airborne water inputs to be deposited in the experimental plot from the sides. The top remains open to maintain natural light conditions and permit vertical water inputs within the cloud-reduction treatment. Given that the curtain exceeds canopy height by around 10 m there should be limited canopy deposition of airborne water within the treatment plot from air moving over the top of the mesh curtain. Most radiation in cloud forest is diffuse, rather than direct, which will minimize the shading effects of the mesh. A 30 by 30 m patch of unmodified forest has been selected 50 m from the treatment as an experimental control.
