    7 === On Wednesday, 28th June === 
    8  
     6=== On Wednesday, 2nd August === 
     7With Juliette. 
     8 
     9Brief remind of the last meeting.  
     10Monthly outputs are implemented, diagnostics are transformed in ferret, new lifetime from Yann oxydant is better (and decreasing from 156 years to 146years). 
     11 
     12I have seen Patrick Brockmann to try putting diagnostics into the monitoring but unfortunately, it is not so easy. 
     13 
     14 
     15__//**TO DO**//__ 
     16   * Continue to implement N,,2,,O modificatio into IPSLCM6.3, 
     17   * Obtain results to do the comparison with Prather article, 
     18   * Ferret transformation: pressure to altitude, 
     19   * Add outputs of burden and loss into INCA. 
     20 
     21 
     22=== On Wednesday, 25th July === 
     23With Nicolas, Didier and Anne. 
     24 
     25Mainly speak about last lifetime results and new simulations. Values are too high again. 
     26 
     27__//**TO DO**//__ 
     28   * Run simulation in order to compare with Prather article (1990-2005) + make comparison figures. 
     29 
     30 
     31=== On Wednesday, 21st July === 
     32With Nicolas, Juliette, Anne and Didier. 
     33 
     34Speaking of coupled model, we have to integrate DMS of Juliette in the code once N,,2,,O is integrated and work. 
     35Try to commit orchidee modification (trusting made by Josefine) then INCA. 
     36 
     37We had a look on vmr and o1d maps from Yann and Zoe simulations. The oxydant I use is an interpolation and we clearly see a discontinuity at a certain level. Didier says that photolyse loss occurs most in high level contrary to burden that is most at low level. 
     38 
     39__//**TO DO**//__ 
     40   * Run simulations with Yann oxydants and new photorate + diagnostics, 
     41   * Check if INCA modification are under GES cpp key, 
     42   * Ask Thibaut where oxydant file comes from, 
     43   * Output of invariant in monthly scale, no more daily. 
     44 
     45 
     46=== On Wednesday, 12th July === 
     47With Nicolas, Juliette, Anne and Didier. 
     48 
     49The main objective of this meeting was to understand why lifetime is so high.  Didier gave me a new photorate formula and new phototable but it remains high. 
     50 
     51Yann has some simulations with N,,2,,O, and Zoe runs in GES configuration so I can see if lifetime/losses and burden are similar to mine. 
     52 
     53__//**TO DO**//__ 
     54   * Do diagnostics on Yann and Zoe simulations, 
     55   * Try to accelerate diagnostics, by using monitoring and timeseries (and transform them into ferret). 
     56   * Coupled model: test with and without ORCHIDEE modifications (interface between orch and inca). 
     57 
     58 
     59=== On Wednesday, 5th July === 
     60With Nicolas, Juliette, Anne and Marion. 
     61 
     62Mainly focus on model versions. It was set to use IPSLCM6.3 with INCA6 and ORCHIDEE3. 
     63 
     64I always have the problem with a high lifetime (up to 150 years). We can test with new photolyse coefficient and new oxydant files. 
    965 
    1066__//**TO DO**//__ 
     
    1268   * Time Series and packoutputs to add + use inter monitoring. 
    1369 
     70 
    1471=== On Wednesday, 28th June === 
    1572With Nicolas, Juliette, Anne and Marion. 
     
    1774Discussion with Anne of configurations I will use in order to transfert N,,2,,O fluxes from pisces to inca. Two meetings was done the week before.  
    1875 
    19 __//**TO DO**//__ 
     76Preindustrial simulations show high lifetime and continuously increasing vmrn2o (no convergence). The diagnostics give a burden that is coherent with data in 39 levels but losses are too low. 
     77 
     78__//**TO DO**//__ 
     79   * Continue simulations with hope of convergence. 
     80   * Play with diagnostics.
