North Tropical Atlantic Index

This is a time series of the three-month running average of the standardized North Tropical Atlantic Index (NATL) -- monthly mean sea surface temperature anomalies averaged over the region 10°N to 20°N latitude and 79°W to 20°W longitude.

The climatological base period for the sea surface temperature anomalies is 1971-2000, and the anomalies are standardized with respect to the period December 1981 to present.
