Share Existing Data

The USA-NPN is developing a list of phenology data sets to make available to the research community and the general public.

Except in a few special cases, we will not be hosting the data ourselves, but will provide metadata and links to the data sets where they exist online. We are interested in data sets that explicitly report phenology, and in those from which phenological data can be garnered.

If you have or know of a data set that you would like to register with us, please follow the instructions below.

Thank you for you interest in making phenology data more readily available.

Instructions for registering a data set

1. If you have not already, create an account on our site.

2. Create a data set record.


If you have a single data set (same location, time period and creator) with multiple files, treat them as a single data set and include a link to the parent directory or a page with links to each file.

If you would like to create several similar data sets, you can create one, and then use the "clone" link (next to "edit") to make a duplicate which you can modify and save as a new data set.


Select the option that best describes the availability of the data for use. Freely available data can be used with no charge, co-authorship or other restriction.  Data that are available based on collaboration often require credit, co-authorship or collaboration with the data creator or curator. Data end users must pay for data with fee-based access. Restricted access data may be sensitive, or unavailable for general use.


Optionally, start typing the title of any publication in the USA-NPN bibliography based on this data set. To submit an new entry to the bibliography click here, add the citation to our database and then return to this page, and start typing the title.


Metadata is “structured information that describes, explains, locates, or otherwise makes it easier to retrieve, use or manage an information resource” (National Information Standards Organization, 2004). If you have an existing metadata record for the data set, identify the standard and upload it in this field. More information on the metadata standards listed is available on wikipedia

Recommended Citation

Optionally enter the citation you would like used for this data set, for example: 

Cross, M. compiler. 1997. Greenland summit ice cores. Boulder, Colorado USA: National Snow and Ice Data Center in association with the World Data Center A for Paleoclimatology at NOAA-NGDC, and the Institute of Arctic and Alpine Research. CD-ROM.


Your data set entry will not be published until you check "published" at the bottom. This enables you to save changes & return to the page when you are ready to submit it. You can also review a list of your published & unpublished data sets here (click on a dataset to edit it).

While few fields are required, the more you fill out the more useful and findable your data set will be.

3. View all submitted & published data set records.
