    22 Juliette made a brief resume of the WP1 meeting, in which I gave a presentation about our work on N,,2,,O. There are two milestones coming in January and May; we might run simulations to intercompare with other groups (AOD variable from 1980 to 2014, AMIP simulation in annual or monthly mean), data will be stored in ESPRI. 
     22We found out why results were different between all our configurations. In fact, for a nudged simulation, PeriodLength was set to 1Y but winds used were monthly. This means that we always run the simulation with the January wind (which is completely different from the August wind). By setting PeriodLength=1M, results are better: no accumulation appears in August and the lifetime is about 164 years. It is still high but maybe changes made due to the test with Yann's files will reduce it.

    24 I recall the simulations I made during this week with some differences between each ones. Anne adds some details on how to proceed to better understand where the problem could come from and propose to have a look at source code to see which difference exist between Yann's code and mine. 
    25 Didier will give me some paths towards simulations he made to see if the problem is present are not (configuration NMHC_AER_S). 
     24We talked a little about AMA and the GA of TRACCS in January: no objection to taking part, but AMA might not be really in the scope of the work.

    28  * Prepare a paper or a page on the difference and results of all those simulation, 
    29  * Send path to Anne, 
    30  * Compute burden in stratosphere only (with nco commands) + compare burden between the beginning and the end of the simulation (inter variability), 
    31  * Keep in mind Orchidee trusting. 
     27   * Run simulation to make comparison with Prather's article from 1985 to 2010.
