PhenoCam Fair Use Data Policy:

Since its inception, the objective of the PhenoCam network has been to serve as a repository for phenologically-relevant, digital, repeat (time-lapse) imagery, and to make that imagery, and derived data products, freely available to a wide array of third-party data end-users, including researchers, educators, and the general public. Thus, imagery from the PhenoCam archive is made publicly available, without restriction, and we encourage you to download imagery and datasets for use in your own research and teaching. 

We request that all publications using PhenoCam data (1) properly cite the appropriate processed PhenoCam dataset (and/or underlying image dataset, if applicable; i.e. Richardson et al. 2017 ORNL DAAC; Milliman et al. 2017 ORNL DAAC), the associated data descriptor (i.e. Richardson et al. 2018 Scientific Data), and other relevant publications; and (2) include both a general acknowledgement for the PhenoCam project and the appropriate site-specific acknowledgements for every site used in your analysis. The text for these acknowledgments is included in the metadata file associated with each PhenoCam site (and bundled with each data download), but as an example, the recommended general acknowledgment reads as follows:

The development of PhenoCam has been supported by the Northeastern States Research Cooperative, NSF’s Macrosystems Biology program (awards EF-1065029 and EF-1702697), DOE’s Regional and Global Climate Modeling program (award DE-SC0016011), the US National Park Service Inventory and Monitoring Program and the USA National Phenology Network (grant number G10AP00129 from the United States Geological Survey), and the USA National Phenology Network and the North Central Climate Science Center (cooperative agreement number G16AC00224 from the United States Geological Survey). PhenoCam collaborators, including site PIs and technicians, are thanked for their efforts in support of PhenoCam. 

While for an example site, Howland Forest, the site-specific acknowledgements read as follows:

Research at Howland Forest is supported by the Office of Science (BER), US Department of Energy, and the USDA Forest Service's Northern Research Station.

For an example of how we recommend this be done, please see the electronic supplement to the following paper:

Richardson, A.D., K. Hufkens, T. Milliman, and S. Frolking. 2018. Intercomparison of transition dates derived from the PhenoCam Dataset V1.0 and MODIS satellite remote sensing. Scientifc Reports 8, Article number: 5679.

Distribution and Re-use Policy:

The PhenoCam Dataset version 1.0, and associated camera imagery, is made freely available under the CC0 Public Domain Dedication.
