Testing Ocean Nino Index Calculations

The Climate Prediction Center has a very nice Ocean Nino Index webpage: here.

Calculations done using CESM2 LENS data

All runs:

Monthly surface temperature anomalies area-averaged over Nino 3.4 region

Detrended monthly surface temperature, then anomalies area-averaged over Nino 3.4 region

Detrended monthly surface temperature, then anomalies area-averaged over Nino 3.4 region, then 3-month running mean

Detrended monthly surface temperature, then anomalies area-averaged over Nino 3.4 region, then standardized by standard deviation

Detrended monthly surface temperature, then anomalies area-averaged over Nino 3.4 region, then 3-month running mean, then standardized by standard deviation

Sample run ONI results for all months:
