How to Reference Datasets

You can use the plots produced from this page in publications. We ask that you acknowledge the Physical Science Division in the publication. For example,

"Image provided by the NOAA/ESRL Physical Sciences Division, Boulder Colorado from their Web site at".

You will also need to reference the datasets directly. For references/citations please go to the wiki page for a current list.
