The M.I.T. General Circulation Model (MITgcm) Release 1 contains code for | 
| 32 | 
  | 
  | 
simulating a wide variety of ocean and atmosphere problems. The model is | 
| 33 | 
  | 
  | 
compatible with platforms ranging from desktop and commodity  | 
| 34 | 
adcroft | 
1.4 | 
cluster x86 systems to high-end multi-processor supercomputers. Minimum | 
| 35 | 
  | 
  | 
requirements are a Fortran compiler (the free g77 compiler is sufficient) | 
| 36 | 
  | 
  | 
and a UNIX like operating system (such as Linux, Solaris, IRIX).  |

A broad span of example problem configurations are included in the | 
| 40 | 
  | 
  | 
release. These examples range from planetary scale  | 
| 41 | 
  | 
  | 
circulation simulations of the ocean and atmosphere to high-resolution, | 
| 42 | 
  | 
  | 
small-scale process studies encompassing non-hydrostatic dynamics. In | 
| 43 | 
  | 
  | 
addition to conventional  | 
| 44 | 
adcroft | 
1.1 | 
prognostic operation, differentiated forms (both tangent-linear and adjoint) | 
| 45 | 
  | 
  | 
of the MITgcm code can be generated automatically using either the TAMC or TAF  | 
| 46 | 
adcroft | 
1.4 | 
automatic differentiation tools. These derivative forms can be used for | 
| 47 | 
  | 
  | 
dynamical sensitivity studies and can also be used, together with appropriate | 
| 48 | 
  | 
  | 
optimisation and  | 
| 49 | 
adcroft | 
1.1 | 
control infrastructure, for mathematically rigorous state-estimation and  | 
| 50 | 
  | 
  | 
data-assimilation. A seamless interface to the ECCO group optimisation  | 
| 51 | 
  | 
  | 
environment is available. |
