 <p>Welcome to the webpage of release 1 of MITgcm.</p> | 
| 32 | 
 The M.I.T. General Circulation Model (MITgcm) Release 1 contains code for | 
 <p>MITgcm </p> | 
| 33 | 
 simulating a wide variety of ocean and atmosphere problems. The model is | 
 <ul> | 
| 34 | 
 compatible with platforms ranging from desktop and commodity  | 
   <li>can be used to study both atmospheric and oceanic circulation</li> | 
| 35 | 
 cluster x86 systems to high-end multi-processor supercomputers. Minimum requirements  | 
   <li>has a non-hydrostatic capability</li> | 
| 36 | 
 are a Fortran compiler (the free g77 compiler is sufficient) and a UNIX like  | 
   <li>has tangent linear and adjoint code maintained alongside the forward | 
| 37 | 
 operating system (such as Linux, Solaris, IRIX).  | 
 model</li> | 
| 38 | 
 <br> | 
 </ul> | 
| 39 | 
 <br> | 
 <p>Here you can:</p> | 
| 40 | 
 A broad span of example problem  | 
 <ul> | 
| 41 | 
 configurations are included in the release. These examples range from planetary scale  | 
   <li><a href=../download_software/index.html>download the code</a></li> | 
| 42 | 
 circulation simulations of the ocean and atmosphere to high-resolution, small-scale  | 
   <li>access on-line documentation</li> | 
| 43 | 
 process studies encompassing non-hydrostatic dynamics. In addition to conventional  | 
   <li>follow tutorial examples of the use of MITgcm in the study of | 
| 44 | 
 prognostic operation, differentiated forms (both tangent-linear and adjoint) | 
 atmospheric | 
| 45 | 
 of the MITgcm code can be generated automatically using either the TAMC or TAF  | 
     and oceanic flows<br> | 
| 46 | 
 automatic differentiation tools. These derivative forms can be used for dynamical  | 
   </li> | 
| 47 | 
 sensitivity studies and can also be used, together with appropriate optimisation and  | 
 </ul> | 
| 48 | 
 control infrastructure, for mathematically rigorous state-estimation and  | 
  | 
 | 
 data-assimilation. A seamless interface to the ECCO group optimisation  | 
  | 
 | 
 environment is available. |
