Explanation of files:

Multi-model ensemble mean monthly mean hindcasts initialized between 2016-2015: 
sst_forecast_lmLM.MME.nc, here LM =0,36 are forecast lead months

Multi-model ensemble mean annual mean hindcasts:
ssh_analog_forecast_Yr2.nc  ssh_analog_forecast_Yr3.nc are hindcasts of SSH at leads of	Year 2 and 3.
sst_analog_forecast_Yr2.nc  sst_analog_forecast_Yr3.nc are hindcasts of SST at leads of Year 2 and 3. 

Corresponding, ssh_trend_Yr2.nc  ssh_trend_Yr3.nc  sst_trend_Yr2.nc  sst_trend_Yr3.nc are the effect of external forcing on hindcasts at leads of Year 2 and 3.

Other hindcast:
For example, sst_nino3.4_initime199701_lt0-3yr.nc is multi-model ensemble mean nino3.4 SST hindcasts at lead times of 0-36 months, initialized on Jan 1997. In this file, for dim "lev", lev=1, 2 3-62 are obs, ensemble mean, and individual ensemble members. 

Control runs: 
modelname_ssh_anom.nc and modelname_sst_anom.nc are SSH and SST from modelname
