1° Analysis
Note: restarts from this analysis are used for the decadal forecast so may be referred to as Decadal
Version: GEOS5odas-5.00: odas-506/D001
Model: MOM4 OGCM (1° X 1° X 50 levels) coupled at every time step with the GEOS-5 AGCM (2 1/2° X 2° X 72 levels) in a Replay mode and the Los Alamos CICE model.
Data Assimilation: Ensemble Optimal Interpolation where the covariances are drawn from a static ensemble. That ensemble consists of the 50 leading state EOFs of a two-year run of 20 different coupled models. The total size of the initial ensemble of perturbations was 1000.
Online Availability: monthly averages from 1960
