Update of the El Nino Southern Oscillations (ENSO) index for the whole period 1993-ongoing
2020-02-07The ENSO index is computed with preprocessed altimeter sea level maps, which are corrected for the annual, seasonal and 60-day signals. However, the sea level maps are not corrected for the long-term trend, which directly affects the final indicator. In January 2020, the processing of the ENSO index has been updated so that the altimeter sea level maps are now corrected for the trend in each grid point. In addition, the reference period used to estimate the periodic signals has been upgraded and...
