Transpose AMIP

17 Nov 09 - Centre's pledge to conduct the tranpose-AMIP experiment
The following centres have pledged to conduct the transpose-AMIP experiment.

Met Office (expt to be run early 2010 by Keith Williams)
NCAR (expt to be run at LLNL by Jim Boyle)
MPI (expt to be run summer 2010 by Bjorn Stevens)
IPSL (expt to be run late 2010/early 2011 by Sandrine Bony)
EC-Earth (expt to be run spring 2010 by Frank Selten)
Meteo France (expt to be run by Michel Deque)

17 Nov 09 - Addition to the experimental design
On recommendation from WGNE, in addition to the core experiment initialised from ECMWF analyses, centres are being requested to optionally submit a second set of experiments. For this second experiment, centres with their own assimilation system should use their own analyses whilst centres without their own assimilation system should be initialised from MERRA re-analyses. More details on the Experimental design page.

2 Oct 09 - Transpose-AMIP II endorsed by WGCM
Transpose-AMIP is now jointly endorsed by WGNE and WGCM. We believe this shows the widespread agreement on the usefulness of the experiment and hope that a large number of centres will participate, both in running the experiments and analysing the data. Catherine Senior has been appointed by WGCM as their representative on the transpose-AMIP steering committee.

28 July 09 - Transpose-AMIP II: Call for diagnostic subprojects
Widespread use of the Transpose-AMIP II data for research purposes is encouraged. A call for diagnostic subprojects has been launched so that the community can see what work is proposed and to act at a catalyst for further subprojects. More details are available here.

07 July 09 - PCMDI agree to co-ordinate data hosting for transpose-AMIP

We're delighted, and very grateful, that PCMDI has agreed to host the data for the project (either directly or through the distributed archive). We see the data sitting alongside the CMIP5 data and sharing much of the archiving/retrieval infrastructure. With their experience of analysing the CAPT data, we expect PCMDI will be interested in leading analysis subprojects and we welcome Steve Klein onto the transpose-AMIP steering committee as PCMDI's representative.

29 May 09 - Transpose-AMIP II to be taken to WGCM for endorsement
Christian Jakob will be presenting the plans for Transpose-AMIP II at the WGCM meeting in September 2009. Having the project endorsed by both WGNE and WGCM should help extend our reach with WGNE representing the processed-based work to feed into parametrization development and WGCM representing most of the climate modelling centres and CMIP5 (which this project has close links to). It is hoped that a representative from both WGNE and WGCM will sit on the transpose-AMIP steering committee.
