Contributing Data

NOAA permanently archives contributions to the World Data Service for Paleoclimatology (WDS-Paleo). 

Data contributions consist of:

  • Metadata
  • One or more data tables including a chronology table (if applicable)
  • Raw data and reconstructions 

Reasons to Contribute

  • Satisfy obligations to publishers and funding agencies
  • Make data freely and permanently available without restrictions
  • Allow colleagues and the general public to discover and use your data 
  • Potential increase in citation rate of your associated articles


Step 1: Review instructions and prepare dataset 

Please follow instructions specific to your contribution type: International Tree Ring Data Bank (ITRDB), International Multiproxy Paleofire Database (IMPD), or all other contributions. Refer to the Frequently Asked Questions for additional information, and contact with specific questions on dataset scope, size, format, or other issues. 

If you are compiling data generated by other researchers or reusing datasets to make a climate reconstruction, refer to instructions for synthesis projects. For data compilations, please contact early in your data gathering process to discuss dataset formats and additional metadata needed to track dataset provenance.

Step 2: Submit contribution

Send completed contribution templates as email attachments to In your email, indicate whether the dataset may become public following WDS-Paleo review or else be held offline until your research has been peer-reviewed and accepted for publication. If you do not receive confirmation of receipt of your contribution within three business days, please phone +1 828-271-4800. 

Step 3: Review and revise contribution 

WDS-Paleo data managers will review your submission and request any clarification or revisions needed to meet contribution requirements. Data managers then upload data files to the WDS-Paleo public server. You will receive a URL link to your data when they are online. Please review your contribution and contact us with any corrections or additions. 

Step 4: Receive a dataset DOI

WDS-Paleo mints DOIs for new datasets, generally within one to two weeks after the dataset becomes public, and adds the DOIs to data files and study landing pages.
