A database of all identified publications that cite SEDAC data is now available. 

Data sets and related data products and services are provided by SEDAC managed by the NASA Earth Science Data and Information System (ESDIS) project. SEDAC is one of the Earth Observing System Data and Information System (EOSDIS) Distributed Active Archive Centers (DAACs), part of the ESDIS project. NASA data are freely accessible; however, when you publish these data or works based on the data, we request that you cite the data sets within the text of the publication and include a reference to them in your reference list. References to data sets, like the examples, below, should have enough detail to provide readers of your publication with the ability to obtain the data sets and conduct their own studies based on your work. (For complete provenance and understanding of specifically which parts of data were used and how, it also may be necessary to describe in detail, within the body of the publication, exactly how the data were used.)  Examples of data set citations are included below.

A recommended citation is provided for each SEDAC data set and appears on the landing page for that data set. The elements contained in the recommended citation can be reorganized for compliance with the particular reference style used by a publisher.

Acknowledgements:

SEDAC strongly encourages its users to cite data or service usage within the reference list of a publication.  In publications where that is not possible an acknowledgement is a general statement that can be used to provide credit to SEDAC for data, assistance, or reviews that have been provided. Please include such statements, either where the use of the data or other resource is described, or within the Acknowledgements section of the publication.  Examples of acknowledgement statements are included below.

Data set:
