This post provides stand-alone illustrations of the HADISST NINO3.4 SST data used in the post Comparison of Annual ERSST.v3b and HADISST NINO3.4 SST (Not Anomaly) Data , without the distraction of the other dataset in the comparison charts. Included are Annual Average, Annual Maximum, and Annual Minimum NINO3.4 SST data, and the difference between the Annual Maximum and Minimum data. Graphs of raw and smoothed data (11-year running-average filter) are provided. Also provided is a comparison of NINO3.4 and Tropical SSTs, both datasets smoothed.
