Hurrell North Atlantic Oscillation (NAO) Index (station-based)
Years of Record: 1865/01 to 2018/04
The winter (December thru March) station-based index of the NAO is based on the difference of normalized sea level pressure (SLP) between Lisbon, Portugal and Stykkisholmur/Reykjavik, Iceland since 1864. Positive values of the NAO index are typically associated with stronger-than-average...

NCAR Sea Level Pressure
Years of Record: 1899/01 to 2018/10
NCAR Sea Level Pressure is a gridded analysis of SLP based on land station reports, covering 1899 to present for latitudes 30°N-90°N. Quality controlled raw data plus empirical corrections for changes in instrumentation and station location.

North Pacific (NP) Index by Trenberth and Hurrell; monthly and winter
Years of Record: 1899/01 to 2018/03
The North Pacific Index (NP index or NPI) is the area-weighted sea level pressure over the region 30°N-65°N, 160°E-140°W. The NP index is defined to measure interannual to decadal variations in the atmospheric circulation. The dominant atmosphere-ocean relation in the North Pacific is one where...
