How to Reference Datasets

You can use the plots produced from this page in publications. We ask that you acknowledge the NOAA/ESRL PSD in the publication. For example, "Image provided by the NOAA/ESRL Physical Science Division, Boulder Colorado from their Web site at http://www.esrl.noaa.gov/psd/".

You should also reference the NARR BAMS article for the NARR data itself:

NORTH AMERICAN REGIONAL REANALYSIS: A long-term, consistent, high-resolution climate dataset for the North American domain, as a major improvement upon the earlier global reanalysis datasets in both resolution and accuracy, Fedor Mesinger et. al, submitted to BAMS 2004.
