Like the CZT-1 site, a number of sensors are arrayed around the Critical Zone Tree 2 to provide spatially and temporally resolved data on the water balance of a single tree. CZT-2 is a Ponderosa Pine (Pinus ponderosa). At this tree, 8 pits are arranged in the cardinal directions, up to 5 m from the tree. Soil temperature, moisture, and matric potential sensors are installed in each pit at depths of 15, 30, 60 cm, and deeper when soil depth allows below the mineral soil surface.

Data control and storage on Campbell Scientific CR1000 dataloggers, using AM16/32B multiplexers.

Soil volumetric water content (VWC) temperature, and electrical conductivity measured using Decagon Devices 5-TE sensors at depths of 15, 30, 60 cm, and deeper when soil depth allows below the mineral soil surface.

Soil matric potential (SWP) measured using Decagon Devices MPS-1 sensor and tensiometers.

Sap Flow measured by the http://www.tranzflo.co.nz/ Heat-Pulse Method sensors spaced radially around CZT-2, facing N, E, S and W.
