Providence Creek headwater catchments

4.6 km2, 1660-2117 m elevation, 8 °C, 1200 mm/yr

The primary Southern Sierra CZO research area is the Providence Creek headwaters, located on the North Fork of the Kings River. The Providence Creek headwaters area varies in elevation from 1660 to 2115 meters. This 4.6 square kilometer catchment is designated as P300. Nested within the P300 catchment are three subcatchments, designated as P301, P303 and P304.

Providence Creek Subcatchment P301

0.992 km2, 1790-2117 m elevation,

The P301 subcatchment is one of the most heavily instrumented and monitored Southern Sierra CZO sites in the Providence Creek headwaters, including the P301 eddy covariance flux tower, critical zone tree, and water balance transect.

P301 Meadows

This string of meadows lies at the head of the P301 stream. Sensors in the wireless network dot the meadow, and installed piezometers and wells track groundwater-surface water interactions.


Critical Zone Tree 1

0.0001 km2,

Inside the P301 subcatchment, the SSCZO established the first Critical Zone Tree. This CZ tree is a White Fir (Abies concolor) that has been intensely instrumented with soil moisture, temperature, and matric potential sensors, snow depth, solar radiation, and sap flow sensors, resin nutrient collectors, tension lysimeters and time lapse photography. The Southern Sierra CZO currently has three instrumented trees.

Providence Creek Subcatchment P303

1.323 km2, 1731-2025 m elevation,

The P303 subcatchment contains a number of sensors and instruments, but the primary ones are the upper elevation meteorological station and the water balance instrument clusters, located at about 1985 m in elevation at the eastern edge of the watershed.

Providence Creek Subcatchment P304

0.487 km2, 1768-1983 m elevation,

The P304 subcatchment has a stream gauging station similar to those located within the other instrumented Providence Creek catchments. As with the other catchments, several micromet sensors are installed within P304.


Flux Towers Transect

Transect area: 568 km2, 405-2700 m elevation,

The Southern Sierra CZO operates eddy co-variance flux towers installed at four different locations varying from 405-2700 meters.


405 m Flux Tower, San Joaquin Experimental Range

513 mm/yr

The SJER flux tower is in the oak woodlands of the foothills at 400 m in elevation. The primary landuse at the San Joaquin Experimental Range is cattle grazing.

2015 m Flux Tower, Providence Creek subcatchment P301

1015 mm/yr

The Providence Flux Tower was the first tower of the Sierra Climate Gradient installed. It was built in 2008, and lies in the Sierran Mixed Conifer belt at the main site of the Southern Sierra Critical Zone Observatory.

2700 m Flux Tower, Short Hair Creek

1078 mm/yr

The Short Hair Creek flux tower is set in the subalpine belt of the Sierra Nevada. Due to harsh winter conditions and a falling tree, the flux tower was down from 2011-2014. A replacement tower was brought in by helicopter and raised by a team in August 2014. Instruments were reinstalled June 2015.

Data Use Policy
Data Sharing Policy
  • Data Use Policy

    DRAFT v.0.4.0

    1. Use our data freely. All CZO Data Products* except those labelled Private** are released to the public and may be freely copied, distributed, edited, remixed, and built upon under the condition that you give acknowledgement as described below. Non-CZO data products — like those produced by USGS or NOAA — have their own use policies, which should be followed.

    2. Give proper citation and acknowledgement. Publications, models and data products that make use of these datasets must include proper citation and acknowledgement. Most importantly, provide a citation in a similar way as a journal article (i.e. author, title, year of publication, name of CZO “publisher”, edition or version, and URL or DOI access information. See http://www.datacite.org/whycitedata). Also include at least a brief acknowledgement such as: “Data were provided by the NSF-supported Southern Sierra Critical Zone Observatory” (replace with the appropriate observatory name).

    3. Let us know how you will use the data. The dataset creators would appreciate hearing of any plans to use the dataset. Consider consultation or collaboration with dataset creators.

    *CZO Data Products.  Defined as a data collected with any monetary or logistical support from a CZO.

    **Private. Most private data will be released to the public within 1-2 years, with some exceptionally challenging datasets up to 4 years. To inquire about potential earlier use, please contact us.

  • Data Sharing Policy

    DRAFT v.0.2.5

    All CZO investigators and collaborators who receive material or logistical support from a CZO agree to:

    1. Share data privately within 1 year. CZO investigators and collaborators agree to provide CZO Data Products* — including data files and metadata for raw, quality controlled and/or derived data — to CZO data managers within one year of collection of samples, in situ or experimental data. By default, data values will be held in a Private CZO Repository**, but metadata will be made public and will provide full attribution to the Dataset Creators†.

    2. Release data to public within 2 years. CZO Dataset Creators will be encouraged after one year to release data for public access. Dataset Creators may chose to publish or release data sooner.

    3. Request, in writing, data privacy up to 4 years. CZO PIs will review short written applications to extend data privacy beyond 2 years and up to 4 years from time of collection. Extensions beyond 3 years should not be the norm, and will be granted only for compelling cases.

    4. Consult with creators of private CZO datasets prior to use. In order to enable the collaborative vision of the CZO program, data in private CZO repositories will be available to other investigators and collaborators within that CZO. Releasing or publishing any derivative of such private data without explicit consent from the dataset creators will be considered a serious scientific ethics violation.

    * CZO Data Products. Defined as data collected with any monetary or logistical support from a CZO. Logistical support includes the use of any CZO sensors, sampling infrastructure, equipment, vehicles, or labor from a supported investigator, student or staff person. CZO Data Products can acknowledge multiple additional sources of support.

    ** Private CZO Repository. Defined as a password-protected directory on each CZO’s data server. Files will be accessible by all investigators and collaborators within the given CZO and logins will be maintained by that local CZO’s data managers. Although data values will not be accessible by the public or ingested into any central data system (i.e. CUAHSI HIS), metadata will be fully discoverable by the public. This provides the dual benefit of giving attribution and credit to dataset creators and the CZO in general, while maintaining protection of intellectual property while publications are pending.

    † Dataset Creators. Defined as the people who are responsible for designing, collecting, analyzing and providing quality assurance for a dataset. The creators of a dataset are analogous to the authors of a publication, and datasets should be cited in an analogous manner following the emerging international guidelines described at http://www.datacite.org/whycitedata.
