+Participants: Joseph, Jorge, Jiandong, Margaux, Thomas, Siteng, Lucas, Franck L., Francois, Antoine,
+              Romain, Antony
+
+News:
+- EMM science team meeting next week (Francois and Siteng will attend in person)
+- The "debug" wiki page by Antoine: https://trac.lmd.jussieu.fr/Planeto/wiki/DebugMode (using gdb)
+
+Recent commits:https://trac.lmd.jussieu.fr/Planeto/log
+==============
+- r2578: First steps towards integrating OpenMP in the physics
+- r2579: Fix missing case for hdo_ice in inichim_newstart
+
+Recent tickets: https://trac.lmd.jussieu.fr/Planeto/report/1
+==============
+- #84: Cleanup physiq (as discussed last week)
+- #85: Compatibility with gfortran 10+
+
+Issues gitlab: https://gitlab.in2p3.fr/la-communaut-des-mod-les-atmosph-riques-plan-taires/git-trunk/-/issues
+=============
+- r2579 should resolve Issue #25
+
+Hot topics:
+==========
+
+* Non-orographic GW with the thermosphere setup (Jiandong)
+- tests with the non-oro GW scheme: crashes right away (at first physics step) as it generates crazy winds
+  at the top of the atmosphere because the tendencies become too large as one goes up.
+- testing behaviour due to other parameters (Cmax, Sc)
+
+* Improving the dust cycle (Antoine)
+- running 10 year-long simulations (currently 5 years done). For now most runs see to be getting too wet.
+
+* Water cycle conservation & stability (Joseph)
+- Two issues: 1) the thermals don't conserve total water and 2) the watercaptag=.true. case generates mass loss (in vdifc)
+
+Francois:
+- there will be reports for CNES contract to write soon (end of december)
+
+Franck:
+- In Edinburgh they work on chemistry with the 1D version of the GCM and will move to 3D.
+  About installation/setup of the model: see the user manual + ask LMD!
+
+Lucas:
+- doing the sub-slope statistics.
+
+Romain:
+- Update on the PEM setup/simulations: looking at the reference 32x24 reference simulations which converges after 77 calls
+  Presumably on a stable solution?
+  Tests with various iteration criteria for the PEM steps.

+              Antony, Lucas, Francois, Joseph, Thomas, Antoine
+News:
+- Occigen will be off-line from Nov 1st 23:00 to November 2nd end of day.
+- There might be some I/O issues on Occigen's workdir... (at least for Ehouarn)
+
+Recent commits:https://trac.lmd.jussieu.fr/Planeto/log
+==============
+- r2570: improve "check_physics_fields" to also look for negative values of tracers.
+- r2571: comments about usage of "extract" and its "offset" parameter for the Time axis
+- r2572-73: Fixes for the picky gfortran v10+ compiler which identifies using a scalar
+            instead of a one-element array as an error (thanks Mike)
+- r2575-76: remove old nucleaco2.F routine ; nucleaco2_mod.F90 is used instead
+- r2577: Fixes for the picky gfortran v10+ compiler which identifies using a scalar
+         instead of a one-element array as an error (thanks Jiandong)
+
+Recent tickets: https://trac.lmd.jussieu.fr/Planeto/report/1
+==============
+- #83: add possibility to keep 1D variables in zrecasted output files
+Suggestion: clean up physiq, especially around the writediagfi in physiq (1d/3d) and many if(flag)
+
+Issues gitlab: https://gitlab.in2p3.fr/la-communaut-des-mod-les-atmosph-riques-plan-taires/git-trunk/-/issues
+=============
+- #25: add hdo_ice in inichim_newstart.F90 => Loic
+
+Hot topics:
+==========
+
+* Water cycle conservation & stability (Joseph)
+- there is a problem in the diagnosis
+- more testing required; multiple problems (1D case, 3D case over a long run)
+
+* Improving the dust cycle (Antoine)
+- we have a satisfactory setting, will do dedicated long run simulations to check the water cycle
+  the main parameter is the ice albedo; injection is 24h/24h
+
+Romain:
+- starting to add OpenMP in the Martian physics.
+- PEM: made tests with 32x32x26 or 32x32x26 simulations over 100 years (vs full simulations)
+       testing with various stop criterion for the PEM iterations between GCM calls
+
+Gabriella:
+- simulations with thermosphere (49 "old" z2sig.def), find a strong increase of water around Ls=100
+  around 80°N (as Francisco did) with iphysiq=10, MY26 dust scenario; possibly linked to the first dust
+  events at that time of year which increase density (at fixed altitude)? Plus using microphysics and
+  radiatively active clouds.
+
+Ehouarn:
+- runing MY36 simulations with thermosphere&ionosphere for EMM & TGO (Ls=0-90).

+- Siteng and Francois go to Dubai for the next EMM science team meeting (8-11th November)
+

+==============
+- r2569: update of the documentation (mostly better handling of http links)

+==============
+- No new tickets.
+
+Hot topics:
+==========
+
+* Water cycle conservation & stability (Joseph)
+- TBC
+
+* Improving the dust cycle (Antoine)
+- Looks a the diurnal cycle with injection at all local times
+
+* Dynamico (Romain)
+- meeting planned with Antoine and Ehouarn for an OpenMP parallelisation of the GCM (also useful for LMDZ)
+- meeting with Ehouarn and T. Dubos to discuss about the coordinates and how to deal with them (i.e. how to create newstart for Dynamico)
+
+Ehouarn:
+- updated the reference "datadir" (https://www.lmd.jussieu.fr/~lmdz/planets/mars/datadir/ ?) to include dust_MY35.nc scenario and daily EUV values for MY35 (Francisco also provided EUV values for the beginning of MY36)
+- working on improving checks at beginning/end of physics to also identify negative tracer values.  => the follow-up question is what to do about these then...
+
+Jorge:
+- ran the mesoscale model w/ Aymeric around Tharsis (w/o water ice in initial state from the GCM). They see in the relative humidity a really strong feature around Arsia, which looks more like the AMEC than their water ice field => look in the microphysics the effect of supersaturation (require a strong one to nucleii), play with the contact parameter (0.90), do some Lagrangian experiment ?
+- is looking for observations to compare to the model and IUVS, especially concerning the expansion velocity (advection? wave propagation?)
+
+Jiandong:
+- runs a simulation to reproduce Gabriella's results
+- will then play with the parameters
+
+Thomas:
+- worked mainly on the VCD web interface
+- asked for rover's data, will not be on the PBS before some time
+
+Lucas:
+- tries to reproduce the results from Etienne (intern in 2018) on Martian microslopes, define some statistics from MOLA32 (test with MOLA64?)
+
+Siteng:
+- writing a manuscript on thermal tides (submission in early November)
+- will run a MY36 soon
+
+Antony:
+- was in Marseille for the exobiology conference last week
+- Dynamico Generic: create start files and will try to run simulations
+
+Christophe:
+- writing the reference paper for CO2 clouds microphysics w/ Anni
+
+Francois:
+- will send Mars Through Time meeting notes
+- was in Marseille for the exobiology conference last week
+
+Aymeric:
+- RAS

+* Water cycle conservation & stability (Joseph)

+- TBC
+
+* Dynamico (Romain)
+- TBC
+
+
+Ehouarn:
+- generated new reference start_archive files (from MCDv5.3 GCM runs). Closes ticket #82
+- contacted Francisco to set up a "final reference" E10.7 EUV input file for MY35 (and early MY36?)
+
+Lucas:
+- want to change the dust forcing in the polar night in the dust scenarios (during global dust storm)
+- looking at the statistics on slopes (for ERC project Mrs through time)
+
+Siteng:
+- investigating thermal tides from TGO/EMM missions. Running GCM  (MY35 & soon MY36) to compare.
+
+Jiandong:
+- running the GCM on Ciclad (and home computers) with full thermosphere to study upper atmosphere.
+  (density of various species to compare to Maven observations).
+- will run with the non-orographic GW scheme and try to tune it
+
+Aymeric:
+- Vincent Caillé is updating the physics in the Mesoscale model to test the CO2 microphysics.
+
+Margaux:
+- tested the water cycle (Joseph's version), gets a slightly different (dryer) water cycle than him
+  after having run 10 years; looses water ~1% per year. Finds occasional ~1e-7 values of q_h2o.
+
+Thomas:
+- mostly working on the VCD and the web interfaces of both MCD and VCD.
+
+Gabriella:
+- runs with Joseph's tuned water cycle + chemistry ("old" 49 layers discretization).
+  Note that chemistry can be initialized from scratch and should converge in less than
+  a year (says Franck L.)
+- for speed, will run with iphysiq=10.
+- is the "thermochem" flag still active/needed or "photochem" flag suffices for chemistry everywhere?
+  Most likely yes, but confirmation from Franck/Francisco would be nice.
+
+Jorge:
+- running the mesocale model (with Aymeric) around Tharsis to compare with GCM and camera images.
