Atlantic Multi-decadal Oscillation (AMO)
Years of Record: 1856/01 to 2016/07
The Atlantic Multi-decadal Oscillation (AMO) has been identified as a coherent mode of natural variability occurring in the North Atlantic Ocean with an estimated period of 60-80 years. It is based upon the average anomalies of sea surface temperatures (SST) in the North Atlantic basin, typically...

NCAR Sea Level Pressure
Years of Record: 1899/01 to 2019/01
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.

Nino SST Indices (Nino 1+2, 3, 3.4, 4; ONI and TNI)
Years of Record: 1870/01 to 2018/10
There are several indices used to monitor the tropical Pacific, all of which are based on SST anomalies averaged across a given region. Usually the anomalies are computed relative to a base period of 30 years. The Niño 3.4 index and the Oceanic Niño Index (ONI) are the most...

Pacific Decadal Oscillation (PDO): Definition and Indices
Years of Record: 1900/01 to 2015/12
The Pacific Decadal Oscillation (PDO) is defined by the leading pattern (EOF) of sea surface temperature (SST) anomalies in the North Pacific basin (typically, polewards of 20°N). The SST anomalies are obtained by removing both the climatological annual cycle and the global-mean SST anomaly...
