Atmospheric model resolution 0.9x0.72 degree lon-lat, 96 vertical levels
Ocean model (if applicable) N/A
Source of atmospheric initial conditions Operational HMCR  3D-Var analysis for upper-air fields; OI analysis for screen-level temperature and humidity;  simplified extended Kalman filter for soil moisture
Source of ocean initial conditions N/A
If Tier-2, what is the source of SST predictions? persistent SST and sea-ice anomalies
