+Ongoing discussions:
+===================
+
+* Comparing GCM runs with TIRVIM (& MCS): (Antoine, Sandrine)
+Sandrine: obs TIRVIM vs "old" GCM (32 layers) and "new" GCM (54 layers) at 30 Pa, worse agreement in the latter.
+          NB comparison is on observations grid (up to 1Pa); evolution of the diurnal cycle worse with "new" GCM
+          => will use "old" (MCDv5.3 like) simulations for now. => rerun and output temp, wind, water, dust 24 times/day
+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...
+
+* Crash with unexpected unrealistic HDO ratio: (Jean-Yves, Margaux)
+HDO_ice ratio of 4000 from the dynamics
+Problem identified (with isotopes) to comes from the dynamics
+
+* 1+1=2:
+Correction to the time axis / housekeeping needed (Romain)
+
+* Dynamico-Mars:
+- what time to set when calling the physics from dynamico?
+
+* Calendar:
+- ptime sent to the physics in LMDZ == end of physics time step minus1 dynamical step...
+  e.g. first time the physics is called ptime=dt_phys-dt_dyn (andnot 0 or dt_phys)
+  why not sent the beginning or the end date of the physical time step date?
+
+
+Joseph:
+- committed at noon today (r2502)the icelocation mode=4 case.
+- the new vdifc doesn't reproduce old results exactly. Check if this is linked to the sub-time stepping
+- investing the water cycle in current Mars changing mtot and albedo, always too dry during the second half of the year
+
+Lucas:
+- pb de calibration of pressure measurements on  Insight; also checking 4 MSL data over 4 Mars years.
+
+Thomas:
+slope winds in the MCD. had some problems (projection issues) with the Coriolis parameter. Fixed now.
+Now uses the PBL heigh (with a min threshold of 300m) to compute reference parameter zfree0 for slope winds to
+account for diurnal evolution, but results not that good. Perhaps add a multiplicative factor to the buoyancy?
