NinoSstTsRmse

Niño3 SSTA time series of El Niño composite temporal RMSE

Description:

Computes the temporal root mean square error (RMSE) of Niño3 (spatial average) SST interannual anomalies composited for a 6 years time series centred on El Niño (detected when December Niño3 SSTA>0.75) between model and observations

Reference observations:

ERA-Interim, HadISST

Region:

Niño3

Smoothing:

time series are smoothed using a 5 months triangle method

Steps (computation):

• El Niño detection
  • interannual anomalies computation
  • detrending (if applicable)
  • smoothing
  • spatial average
  • La Niña years selection
• metric computation
  • interannual anomalies computation
  • detrending (if applicable)
  • smoothing
  • spatial average
  • 6 years time series centred on El Niño events creation
  • RMSE computation

Time frequency:

monthly

Units:

°C

Variable name:

sea surface temperature (SST)
