Under this license, derived products and redistribution are allowed, but you are required to always inform your users of the original source of the data used, refer them to the license text and the original source at SITES for possible updates or uploads.

You are free to:

  • Share — copy and redistribute the material in any medium or format
  • Adapt — remix, transform, and build upon the material for any purpose, even commercially

Under the following terms:

  • Attribution — You must give appropriate credit, provide a link to the licence, and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use
  • No additional restrictions — You may not apply legal terms or technological measures that legally restrict others from doing anything the licence permits

The licensor cannot revoke these freedoms as long as you follow the licence terms.

The SITES data products are provided "as is", without warranty of any kind, expressed or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose, title and non-infringement. In no event shall the copyright holders or anyone distributing the SITES data products be liable for any damages or other liability, whether in contract, tort or otherwise, arising from, out of or in connection with the SITES data products.

Data from the SITES Data Portal must be properly cited and acknowledged.


Citation of a dataset is handled similar to that of a publication. On the metadata page of the dataset a citation is provided.

Example: Svartberget Field Research Station. 2019. Meteorological from Degerö, 2000-12-31 – 2014-12-31. SITES Data Portal.

The persistent identifier (DOI or PID) will always lead you back to the metadata page where be able to download the data object again or check for updates.

You may also use or link to pictures and use visualisations obtained from SITES Data Portal if you add the link to the original and the text "SITES, licensed under CCBY" followed by the link to the original source.


We urge you to contact and inform the data providers when the data is used for publications and to offer them the possibility to comment and/or offer them co-authorship or acknowledgement in the publication when this is justified by the added value of the data for your results.

Any publication using SITES data must include the following statement in the acknowledgement: "This [study/report/dataset/etc.] has been made possible by data provided by the Swedish Infrastructure for Ecosystem Science (SITES)."

Identification of data throughout its lifecycle is essential. This can be achieved by allocating unique and persistent digital identifiers (DOI or PID) to data objects. The link provided will always resolve to its landing page (metadata page).

The PIDs allow to make unambiguous references to data during curation, cataloguing and support provenance tracking. They are also needed for correct citation (and hence attribution) of the data by end users.

In short, in today’s expanding world of open data, PIDs are essential tools for establishing clear links between all entities involved in or connected with any given project.
