Sensors & Field Instruments

The Reynolds Creek CZO benefits from extensive instrumentation established and maintained by the USDA ARS NWRC. The CZO will also expand the current array of instrumentation. This network is critical because it forms the basis for understanding how the soil environment varies over time and space.

Current USDA-ARS instrumentation of RCEW

The existing scientific infrastructure is a key advantage for the RCEW site as a CZO. Most CZO sites require substantial funding to produce a hydro-meteorological network that is currently available at the RCEW. The existing, publically available hydroclimatic data are long-term and spatially extensive
