ARCHIVED CONTENT: In December 2020, the CZO program was succeeded by the Critical Zone Collaborative Network (CZ Net) ×


CZ science uses integrated, diverse data

Data integration is a key requirement for Critical Zone scientists to inform our theoretical frameworks, constrain our conceptual and coupled systems models, and test our model-generated hypotheses -- both within a CZO and across the CZO network.

Our data are highly interdisciplinary and span a wide range of time and spatial scales. Data types include those from sensors and samples.

Integrated Data System

The CZOs are working together to develop cross-CZO capabilities for sharing, integrating, analyzing, and preserving CZO data.


CUAHSI HydroShare enables groups and individuals to share data and models: 
 storage, analysis, and publication.

Migration to CUAHSI’s HydroShare
CZO is partnering with CUAHSI to migrate our data catalog from to CUAHSI’s repository in 2019.  Migration goes well beyond moving our metadata.  It will also help us

  • Gain a central, long-term data repository.
  • Improve search and browse.
  • Enhance collaboration among CZO researchers and their partners.

Collaboration with Clowder on HydroShare migration
CZO and CUAHSI are collaborating with the Clowder team (led by NCSA), with emphasis on authoring metadata and interoperability between HydroShare and Clowder. Clowder is online software that helps communities manage research data via customized data catalogs and data processing tools.

Dataset Listings

Primary data access

Dataset Listings = Centralized metadata catalog at

  • 400+ datasets across the network 
  • 2000+ URLs pointing to files & webpages
  • Millions of data values
  • Browse 70 main topics including Meteorology,  Soil Moisture, GIS/MapData,  Streamflow/Discharge, Precipitation, 
Soil Temperature, LiDAR, Stream Water Chemistry… 

CZO dataset listings
National | Boulder | Calhoun | Catalina-Jemez | Christina | Eel | IML | Luquillo | Reynolds | Shale Hills | Sierra
Dataset listings have a standard metadata format and point to data produced by CZO as well as related data produced by non-CZO organizations (ie USGS, NOAA, 
USDA, NEON, LTER).  Links to data files are provided.  Data files and databases are *not* hosted here on Instead, they are hosted by national data repositories, individual CZO data catalogs, federal data centers, and other sources.  File types range widely, including CSV, Excel, and JPG.  Files are grouped into collections called "datasets", which are organized by discipline, topic, creators, field areas and/or variables.  

Network data products
In the past few years, CZO data managers have been synthesizing more of CZO’s common measurements and partner data into cross-network data products.  Example dataset listings for these products include:

Other Data Access

Alternative access points

Data catalog websites
Boulder | Calhoun | Catalina-Jemez | Christina |  Eel | IML-map | IML | Luquillo | Reynolds | Shale Hills | Sierra
These websites provide an alternative access point for an individual CZO, with differing interfaces.  Much of these data are also available via the standardized Dataset Listings (primary access point).

Non-CZO repositories 
IEDA EarthChem | CUAHSI Hydroshare | KNB | LTER-NIS | OpenTopography
Individual CZOs have submitted some of their data to be archived (or soon will be archived) by data center organizations such as those listed above.

More than 760 CZO data resources are automatically ingested into the CINERGI inventory from the CZO Data Search Portal API (see below pilot projects). CINERGI contains more than 1 million metadata records across many disciplines of the geosciences.  The metadata are semantically enhanced.

Pilot projects
(may not be fully functional or complete)
CZO Data Search Portal - Power search and filtering. All portal metadata is available via web services API access.
CZO Data Visualization Portal - Map-based searching and data visualization. Includes some remote sensing and time-series data. 


Data Polices & Guidelines

Information about data use and data sharing

Data Use Policy 
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 on subsequent pages.  

Data Sharing Policy 
CZO investigators and data managers are expected to make their data publically available as soon as possible.  

Data Sharing Guidelines 
CZO investigators and data managers should follow these guidelines.   For example, metadata should be submitted to, which enables data searching across observatories



Overview of the integrated CZO Data System

A national CZO Data integration effort is leveraging international data standards, cyber-infrastructure developments and new technologies to assist CZO investigators and data managers with sharing data in a manner that enables high-level integration and supports the Theory-Model-Data fusion approach to Critical Zone science. Learn more about the CZO Data System.


Tool Development

Data management software

With our partners, CZO has contributed to a series of software projects that help structure and manage our diverse data.  They include:

  • ODM2 - Robust data model for Critical Zone science.
  • ODM2 Admin - Management of sensor and sample-based data collected from a field site.
  • Clowder - Customized data catalogs in the cloud to help manage research data for groups and communities.
  • Dendra - Interface for sensor database, University of California’s SensorBase.


A few examples of the many kinds of field instruments and sample collection resources employed by CZO.
