    21 Now, simulation on pre industrial period is good. The pressure evolution seems to depend on temperature (sst) or anything else that does not correspond to pre industrial period (slight increasing around 2008). 
     21Presentation of recent results for the present day run, with: 
     22 1) Data used (BBG, NAT and ANT); 
     23 2) Results of vertical profiles and total loss for 2000 (year with an imposed rescaling at 316 ppb); 
     24 3) Results over the whole period (2000-2007) with vertical concentration, surface concentration, total loss and burden.

    23 Next week (or the one after), Anne will be invited to learn more about configuration/physics/radiative code and to converge step by step towards a coupled version. 
     26Oceanic emissions seem constant over 150 years: Marion says it is okay, because N2O concentration are not so modified with increase of temperature and so on. 
     27 
     28Discussion about the rescaling factor: if it is too low, it means that emissions are low too; if the correction is too big, emissions are too important also.

    26  * make graph of evolution of loss (same as vmrn2o); 
    27  * run a simulation with some imposed year as 1980. 
    28  * continue to develop code for present days. 
    29  * keep in mind the work with large region (CEDS inventories, see Maureen). 
     31 * Chart of CEDS without soil emissions category, 
     32 * Plot BBG emissions in same units than others graphs (meaning in Tg/yr) 
     33 * Invest if it is possible to recover input emissions from surface concentration and total loss (in order to better reconstruct emissions)
