Based on the GDEMV3 monthly climatology temperature and salinity data files, the climatology file for IAS were constructed.

GDEMV3: horizontal resolution 0.25 degree 78 vertical standard levels from 0 to 6600m

To construct zeta, u, v, t, s, ubar, vbar

The level of no motion: 2000mCalculate dynamic height and then geostrophic velocity. Ekman flow is also added.Through vertical integration of velocity to get ubar, vbar.
