Summary
Abstract: The North Pacific (NP) Index is the area-weighted sea level pressure
(SLP) over the region 30N-65N, 160E-140W and is used to measure
decadal variations linked to El Nino (ENSO) and La Nina events.

The NP data set consists of;
- Monthly NP Index
- November-March NP Index
- November-March NP Anomaly Index

The NP data set is available from:
