NASA data are freely accessible; however, when you publish these data or works based on the data, we request that you cite the datasets within the text of your work, and include references to the datasets in your reference list.
References to datasets should have enough detail to allow your audience to obtain the datasets themselves 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 your work, exactly how the data is used.)
Because each discipline within Earth science has its own unique approach to data, each dataset provider has posted examples on how to cite and reference its discipline-specific data and services.
