    <p>The <b>MITgcm</b> (<b>MIT</b> <b>G</b>eneral <b>C</b>irculation
      <b>M</b>odel) is a numerical model designed for study of the
      atmosphere, ocean, and climate. Its non-hydrostatic formulation
      enables it to simulate fluid phenomena over a wide range of
      scales; its adjoint capability enables it to be applied to
      parameter and state estimation problems. By employing fluid
      isomorphisms, one hydrodynamical kernel can be used to simulate
      flow in both the atmosphere and ocean.</p>

    <p>You are welcome to <a href="http://mitgcm.org/source_code.html">
      download</a> and use MITgcm.</p>

       News is back by popular request. New advection schemes are currently
       being tested. Some preliminary results from the new schemes can be seen 
       <A href=news/advection_testing_jan07/advection_testing.html>
       here.
       </A>
       The plots show a tracer being transported and stretched in the
       MITgcm advect_xz verification test. Both new schemes (OS7MP
       and Prather second-order scheme with limiting) have very low implied 
       diffusivity.
       We are currently evaluating the
       schemes to assess their implied diffusivity, with a bottle of 
       Jean-Michel's favorite Belgian
       beer going to the the least diffusive scheme - watch this space!

       A short article entitled 
       "NASA Supercomputer Improves Prospects for Ocean Climate Research"
       in the current EOS (volume 86, number 9, March 1 2005)
       gives a succinct overview of some of the advanced high-resolution
       state-estimation work being undertaken with MITgcm by members 
       of the ECCO consortium. The article describes 
       ground-breaking computational

        MITgcm is now able to write and (to a lesser extent) read NetCDF files.
        The framework (the "MNC" package) has been tested by numerous developers
        on literally dozens of machines and, for the past month, has been a
        working part of our standard verification suite.  We encourage MITgcm
        users (especially new users) to try out the MNC package since the model
        output is now much easier to read and understand.  For further NetCDF
