Atmosphere Model Intercomparison Project (AMIP) is part of the [[CMIP]] family of intercomparison projects. In an AMIP run the model is run with simulated atmosphere and land, and prescribed ocean and sea ice.
  
AMIP runs are stored in the UMUI under experiment saaq. Versions 1.0 and 1.3 of the ACCESS model are available, as well as a lower-resolution N48 version of 1.3. There is additional information about these jobs available on the [https://trac.nci.org.au/trac/access/wiki/ACCESS_AMIP_testcases | ACCESS trac site].

Copy the job '''saaqb''' to your own experiment. Open it in the UMUI and change the User-id to your NCI username in '''User Information->General Details'''. Compile the run by selecting '''Compile and build''' in the '''Compilation and Modifications->Compile options''' panel for '''both''' the model and reconfiguration (Due to the extra fields in the AMIP run it can't use the standard reconfiguration). You can then process and submit the job.

Once the compile job on Vayu has finished change the '''Compile options''' settings to '''Run from existing executable''', process and submit the job once more and the simulation run will start.

==Verification==
 
 
 
To ensure you are getting the correct results you can check the values of the '''Final Absolute Norm''' in the UM .leave file. The first few values should be:
 
<syntaxhighlight>
 
  Final Absolute Norm :  7.276956451914318E-003
 
  Final Absolute Norm :  4.715657804189433E-003
 
  Final Absolute Norm :  9.433036729385244E-003
 
  Final Absolute Norm :  8.127311324946143E-003
 
  Final Absolute Norm :  8.737187347119101E-003
 
  Final Absolute Norm :  9.758734323322731E-003
 
  Final Absolute Norm :  8.330291277356124E-003
 
  Final Absolute Norm :  8.961952297931315E-003
 
  Final Absolute Norm :  9.903317054337587E-003
 
  Final Absolute Norm :  9.932131133228725E-003
 
</syntaxhighlight>
 
You can easily see these by using grep and head on the .leave file, e.g.
 
<syntaxhighlight>
 
grep 'Final Absolute' saaqb000.saaqb.d000000.t000000.leave | head
 
</syntaxhighlight>
 
If you see any difference between your results for an unmodified run and the expected results please let the CMS team know at [[mailto:access_help@nf.nci.org.au | access_help@nf.nci.org.au]].

Atmosphere Model Intercomparison Project (AMIP) is part of the CMIP family of intercomparison projects. In an AMIP run the model is run with simulated atmosphere and land, and prescribed ocean and sea ice.

CMIP6 Era

ACCESS CMIP6-era AMIP runs are not yet available as of Nov. 2019

CMIP5 Era

ACCESS CMIP5-era AMIP runs are started using the UMUI

Versions 1.0 and 1.3 of the ACCESS model are available, as well as a lower-resolution N48 version of 1.3. There is additional information about these jobs available on the ACCESS trac site.
