  • General

    What technology does CUAHSI use to share and manage?

    We encourage users to publish their time series data using the Hydrologic Information System (HIS), which makes data widely discoverable. Time series data also can be published using HydroShare, which can also accommodate any type of data. In addition, HydroShare has more robust collaboration tools. Contact CUAHSI staff to discuss the best method to publish your data. 

    What is the funding model for CUAHSI?

    CUAHSI's core funding comes from a 5-year cooperative agreement with the National Science Foundation; EAR-1849458. CUAHSI also has project-based grants and contracts with other agencies and philanthropic foundations. 

    Does CUAHSI provide technical support?

    Yes. Please contact help@cuahsi.org for all support questions. We strive to respond to all inquiries in a timely manner and will schedule teleconference meetings upon request.

    Is the source code for the tools available?

    Yes, all CUAHSI tools and software are open source. You can find the source code on github at https://github.com/cuahsi and https://github.com/hydroshare.

    I encountered a problem how do I file a bug report?

    Please contact help@cuahsi.org or find us on github.

  • Finding Data

    Where can I find data?

    There are several methods for accessing water science data. Access time series data using our web client: http://data.cuahsi.org or programmatically via a REST API. 

    HydroShare has a Discover page for search in addition to a REST API. 

    For more information on finding data, visit our Data Discovery and Analysis page. 

    How Frequently does the U.S. Geological Survey's National Water Information System (NWIS) data get updated?

    The USGS NWIS services, listed below, are updated every week on Saturdays.

    What kind of data are available from CUAHSI Data Services?

    HydroClient provides access to time series data like stream gauge measurements, meteorological station measurements, repeated “grab” samples, and soil moisture measurements. All data are returned in the same format. For more information see the User Guide. 

    HydroShare provides access to a broad set of hydrologic data types that include time series, geospatial, models, and more. Learn more about HydroShare here.

    Does CUAHSI provide access to international data?

    Yes, in addition to data in HIS and HydroShare, CUAHSI provides access to a number of regional and global data portals here. 

  • Publishing Data

    How can CUAHSI help me with my Data Management Plan?

    A Data Management Plan (DMP) should be a part of any project in which new data are collected or compiled. The DMP details the storage, archiving and dissemination plans for data resulting from NSF-funded projects. CUAHSI has compiled guidance based on NSF's Proposal & Awards Policies & Procedures Guide that may assist in completion of a DMP. 

    How can I publish my data?

    The Data Publishing page provides detailed instructions depending on the type of data you working with (e.g. time series, geospatial, model, etc.)

    Is there a limit to how much data I can publish with CUAHSI?

    Please contact help@cuahsi.org to discuss your specific situation for large data sets. 

    Can I host data on my own server or does it have to be on CUAHSI servers?

    Although CUAHSI now encourages all users to leverage our cloud-based data publication, time series data can be hosted using your own server. Please contact CUAHSI if you wish to publish your data to HIS from your server. 

    Are there any costs associated with publishing my data?

    No.

    I’m not from a US academic institution, can we still use your services?

    Yes.
