Precipitation data were collected from a ridgetop climate station East of Niwot Ridge (B1 at 2591 m) throughout the year using a chart recorder. Initially, instrumentation consisted of an 8-inch metal rain gauge with receiving rim about 3 feet off the ground and measurements were made on approximately weekly basis. More recently, instrumentation consisted of a Fegusson type weighing rain gage. Precipitation was caught in a bucket containing ethylene glycol (to melt snow) and light oil (to prevent evaporation). Asthe weight of the bucket increased, the pen moved up via a spring mechanism and recordedona rotating chart. Precipitation was recorded on a continuous basis.
An EasyEntry program was written in order to efficiently get the precipitation data contained in the 3 Marr et al. reports (listed above) into an electronic form. Data were entered and rekeyed during the early summer of 1993 by Susan Kindig and Mike Sannes. The resulting files were further processed and archived on niwotlter, the NWT LTER server. These files were the source of the data that appear in the data section in this file.The weighing-bucket gauges are currently not in use, although partial precipitation records may exist for the post-1964 period. For periods where the precipitation quantity represents more than a 24-hr period, that quantity is recorded on the final day of the period and the number of days over which that quantity occurred is given in the final field.Metadata for B1 climatological data from other sources can be found at:http://niwot.colorado.edu/meta_data/b-1dp219.ml.meta.txthttp://niwot.colorado.edu/meta_data/b-1mtape.ml.meta.txthttp://niwot.colorado.edu/meta_data/b-1hobo.hourly.jm.meta.txt

Data Use Policy
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
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.
