The OCCAM 66 level model: model description, physics, initial conditions and external forcing

This report contains information on the 66 level OCCAM global model with full surface forcing, improved model physics and a sea-ice model with elastic-viscous-plastic dynamics and three layer thermodynamics. The first run of the model at a horizontal resolution of 1/4 degrees x 1/4 degrees is also described together with details of the format of the output files available for analysis.
