How to Reference Datasets and Plots
You can use the plots produced from this page in publications. We ask that you acknowledge the NOAA/ESRL Physical Sciences Division in the publication. For example,
"Image provided by the NOAA/ESRL Physical Sciences Division, Boulder Colorado from their Web site at http://www.psd.noaa.gov/".
You should also reference the NCDC Climate Division Dataset.
