NinoSstLonRmse

Equatorial SSTA of El Niño composite zonal RMSE

Description:

Computes the zonal root mean square error (RMSE) of equatorial Pacific (meridional average) December SST anomalies composited during El Niño events (detected when December Niño3 SSTA>0.75) between model and observations

Reference observations:

ERA-Interim, HadISST

Region:

equatorial Pacific

Regridding:

model regridded toward observational grid (using cdms esmf linear method)

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
  • December selection
  • regridding (if applicable)
  • meridional average
  • El Niño composite creation
  • RMSE computation

Time frequency:

monthly

Units:

°C

Variable name:

sea surface temperature (SST)
