Abstract
**Some of these files are currently listed as private. Please direct access inquiries for these data to Data Manager Xiande Meng.**
Click on Parent Folder to access all data and metadata that are currently available. Metadata include site properties, instrumentation, and processing notes.
You may also click on individual Water Year (WY) dataset links to immediately download a file of the data.
NOTE: We are working to update individual WY data listings on this site. Current individual WYs listed below may not represent all available data and metadata. Click on the Parent Folder link to access all files.
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.
