Field notes
The page separates NOAA's weekly Niño-3.4 index from its monthly measure and explains that the two use different baselines. It pairs sea-surface temperature with chlorophyll near Peru, sea-level anomalies, coral-bleaching alerts, and comparisons against earlier records; readings younger than 15 days may be revised. A linked Methods section names datasets including NOAA OISST, CPC, and Copernicus DUACS.
