Water from ground to sky - New approaches to observing and predicting field to basin scale Evapotranspiration (ET) over crops and plantations
How tall? The taller the tower, the large area ET you measure (around 10-100x upwind of tower). Needs to be at least ~6 feet above canopy. How much power? Can be run on solar, continuously log data at ten times a second, output ET and carbon fluxes every 30 minutes.
