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...

QBO: Quasi-Biennial Oscillation
Years of Record: 1953/01 to 2012/09
The quasi-biennial oscillation (QBO) is a quasi-periodic oscillation of the equatorial zonal wind between easterlies and westerlies in the tropical stratosphere with a mean period of 28 to 29 months. The alternating wind regimes develop at the top of the lower stratosphere and propagate downwards...

TRMM: Tropical Rainfall Measuring Mission
Years of Record: 1998/01 to 2016/10
Note: After 17 years (1997-4/2015) the TRMM mission came to an end. NASA and the Japan Aerospace Exploration Agency (JAXA) stopped TRMM’s science operations and data collection on April 8, 2015 after the spacecraft depleted its fuel reserves. The Global Precipitation Mission (GPM) is the...

The Tropical Ocean Global Atmosphere program (TOGA) is a component of the World Climate Research Programme (WCRP) aimed specifically at the prediction of climate phenomena on time scales of months to years. In order to achieve the TOGA goals, a strategy of large-scale, long-term monitoring of the...
