1. Earth system model of INM RAS Volodin E.M., Galin V.Ya., Diansly N.A., Gusev A.V., Smyshlyaev S.P., Yakovlev N.G. Institute of Numerical Mathematics RAS e-mail: volodin@inm.ras.ru

2. Model includes 2 main blocks: atmosphere and ocean. Atmosphere: spatial resolution is 5х4, 2х1.5 or 1.25х1 degrees in longitude and latitude. In vertical 21 levels (uppermost level at 30 km) or 39 levels (uppermost level at 90 km), or 80 levels (uppermost level at 90 km). Time step is 3-12 minutes. Equations are solved by finite difference method. Ocean: spatial resolution is 1x0.5 degrees in longitude and latitude and 40 levels in vertical. Time step is 2 hours. Equations are solved by finite difference method at spherical coordinates with shifted poles. Model includes sea ice dynamics and thermodynamics block. Exchange between atmosphere and ocean occurs at each time step of ocean model, without flux adjustment.

3. The model can include also: 1. Chemistry block that can take into account 74 spices and about 150 reactions of chlorine, bromine, nitrogenous, oxigenous, hydrogenous, sulfuric cycles. 2. Carbon cycle (calculation of carbon of plants, soil, ocean and atmosphere) 3. Methane cycle (emission from wetlands, atmospheric concentration). 4. Dynamical vegetation. 5. Parameterization of electric phenomena (flashes, ionospheric potential)

4. The model code is written as 3 independent tasks: Atmospheric dynamics, oceanic dynamics and atmospheric chemistry, that exchanges data through hard disk. The model with atmospheric resolution 2x1.5L21 and oceanic resolution 1x0.5L40 that is used for CMIP5, runs for 6 years in 1 day at 56 cores of Intel Xeon 2.66 GHz.
