+- #87 : Move from "F77" calls to Netcdf to "F90" to alleviate problems with gfortran10+
+- #88 : Make D/H ratio of northern cap water ice a parameter (used set?) rather than have it hard coded in hdo_surfex_mod
+- #89 : Make Vienna Standard Mean Ocean Water (VSMOW) a constant parameter (in comcstfi_h) rather than have it hard coded
+        to 155.76E-6 in various routines
+- #90 : Cleanup use of rnew, cpnew from module conc_mod : because these change at every time step they should not
+        be set/read as module variables but passed to routines as arguments
+
+-TODO: clean up the tickets (some are old and obsolete but not closed)
+
+Hot topics:
+==========
+
+* Non-orographic GW with the thermosphere setup (Jiandong)
+- all the bugs in the parametrization are now fixed (confusion between tendencies and increments,
+  using rho in EPflux computation and including rho at launch altitude)
+- Now will run the GCM and retune the parameters by comparing to MCS.
+
+* Improving the dust cycle (Antoine)
+- Did some simulations to compare with Joseph's with his start files.
+  But with new dust cycle => got different results than previously
+  Now finds a drier water cycle. Differences come from the scavenging parametrization
+  with adds water to the system... => there is a big in the scavenging which adds water...
+  (scavco2cond flag, which is .false. by default)
+
+* Water conservation...
+- To be continued...
+
+* OpenMP:(Romain)
+- most routines OK in OpenMP
+- Latest tests show that 1/=1 with MPI with thermosphere... related to  euv heating
+
+Gabriella:
+- is stuck as starts from Joseph contain NaNs...
+
+Tanguy:
+- working on Mars2020 (supercam + microphone measurements)
+- some NASA AMES GCM work (coagulation of dust)
+- Bob Haberle is investigating temperature non-equilibrium between dust & atmospheric surroundings (AGU poster)
+
+Francois:
+- will organize a group meeting of MAMO local organisers on the first week of January

+==========
+
+* Improving the dust cycle (Antoine)
+- the test with I=1500 and albedo of ice/frost of 0.4/0.6 (7MY for now, still running) returned a very DRYING water cycle
+  => maybe some room for a frost albedo between 0.4 and 0.6 to stabilize the water cycle at a reasonable level
+- in parallel, he is running simulations at 54 and 26 levels to strictly compare the effect of the new dust cycle (Joseph is running these with the old dust cycle)
+  /!\ compared to Antoine's previous simulations, these :
+       use revision r2592 of the model (versus r2577) ;
+       use converged state start files for the water cycle ;
+       don't use non-orographic gravity waves ;
+       don't use scavenging by CO2 ice ;
+       have some differences on the dissipation and sponge layer.
+  => still running, but seems to result in a drying water cycle, at the opposite of his previous simulations... to be confirmed
+- Gathering his work for the annual CNES report
+
+* Non-orographic GW with the thermosphere setup (Jiandong)
+- achieves to run a whole MY under some circumstances, but with extreme variations (8e5K !!) for temperature during month 8, when the breaking level goes up 20-40km higher than usual (because dusty season)
+  These extreme variations appears only in stats file, not diagfi...?? Month 9 normal.
+  Sometimes it crashes at month 10, when these extreme variations reappear...
+- will compare first months with MCS
+
+Romain:
+- OpenMP le GCM : only thermosphere left to do ! but gets some issues when he tries to implement it
+- PEM : simulations with current ice caps and obliquity 40. converge well toward an equilibrium state, without oscillations !
+
+Jorge:
+- Analysed simulations around Ls120 at Ascraeus Mons, where obs detect elongated cloud
+- On Arsia Mons : cloud pocket in the model, but bad representation of the cloud itself -> working on the microphysics with Francois (contact parameter)
+
+Thomas:
+- Looks at the mesoscale model to better compare with its MCD slope winds model
+- Web page for retrieving full MCD version almost ready
+- waiting for comments on his papers (solar panels)
+
+Lucas:
+- Has a bug in his subslope parametrization : sometimes atm temperature too low around the surface.
+  + thinking on how to account for subslopes when going back to the whole cell : mean/sum, TCO2cond...?

+- bug with watercaptag and sub-timestepping identified (in 1D). There might be other issues.
+  Joseph will commit the correction.
+
+* Improving the dust cycle (Antoine)
+- tuning the combined dust & water cycle. For now too wet. Drying the water cycle will involve changing
+  thermal inertia and albedo of frost towards more realistic values. The contact parameter function could
+  also be improved.
+
+* Non-orographic GW with the thermosphere setup (Jiandong)
+- Looked thoroughly at the equations and way they are written and used in the code.
+  Proposes some improvements about intermediate computations of altitudes and BV and scale height,
+  and more stable evaluation of rho (including variation of r).
+  Overall yields a good impact on the effect of the parametrization (more constrained to act on
+  lower altitudes in the thermosphere than the model top).
+- Other big problem: there was a mix-up between increment and tendency due to the problem.

+- Antoine: Fix erroneous dust opacities appearing in the southern polar night when using "dustradadjust". These opacities follow the baroclinic waves structure. Suggestion : work at the fortran code level from a appropriate start files, output with write(*,*) when and where there is the bug, end with "STOP" and try again and again...
+
+- Thomas : Slope winds. Struggle with the coriolis forces. Need to remove the sensitivity of friction to stability (Richardson). The fit is not yet perfect but not bad. Francois suggests to use anomaly (diurnal mean ave - instantaneous) even for the computed slope winds for comparison
+
+- Siteng : analysis of the role or a priori in the TIRVIM inversion and comparison with GCM
+
+- Antony and Romain : fixed the problems with tracers in Dynamico - Mars. Soon will do realistic Mars simulations ! Work on XIOS output
+
+- Antony : test on the effect of the dissipation on warming early Mars.
+
+- Margaux Vals : new results on D/H cycle and the model. 2 papers in preparation...
+

+          NB comparison is on observations grid (up to 1Pa); evolution of the diurnal cycle worse with "new" GCM

+Antoine: Comparions with MCS; "new" run seems slightly warmer (looking at 3am+3pm diurnal ave). Overall a difference
+         in the phases seems slightly better in the "new" run.
+
+* Brutal drying up in the thermosphere issue: (Francisco, Margaux)
+Francisco is focusing on the simulation where it happens
+Margaux is checking in various past revisions if the problem is still there. So far the problem always arises (even in 4 year old models). Has a test with 32 layers showing that the problem seems correlated to using the photochemistry...
