+'''9^th^ September 2021'''
+{{{
+
+Duration:1h
+
+Participants: Jiandong, Christophe, Lucas, Francois, Romain, Antony, Ehouarn, Antoine, Siteng, Sandrine, Margaux,
+              Joseph, Aymeric
+
+News:
+====
+- Jiandong Liu arrived at LMD for his 1 year long postdoc.
+- Science fair on 8-10 October with Mars stuff. Volunteers needed!
+
+Recent commits: https://trac.lmd.jussieu.fr/Planeto/log
+==============
+- r2558: MCS observables simulator, now computes column-integrated dod
+- r2559: Cleanup of the wstats routines to generate the GCM's "stats.nc" file
+         (a first step towards fixing ticket #81)
+
+Recent tickets: https://trac.lmd.jussieu.fr/Planeto/report/1
+==============
+- None
+
+Hot topics:
+==========
+
+* Improving the dust cycle (Antoine)
+- cdod ratio between MCS column and GCM column normalized
+ looking at median valies (means can be quite large)
+ much more dust in GCM than MCS in the clear season (in daytime)
+ more comparable ratios during nighttime
+
+* Dynamico (Romain)
+- Nothing new (Occigen off-line this week)
+
+Romain:
+- Planetary Evolution Model: stop substep criterion on surface ice change
+  seems to work fine
+- tests using lower resolution GCM to run faster (and to compare to full GCM-only run)
+
+Christophe:
+- 8 year simulation seems converged. To be further analyzed.
+
+Sandrine:
+- ACS Tirvim observations: thermal tides, looking at zonal
+  temperatures => diurnal & semi-diurnal modes,
+  compares well to GCM, increasing amplitude with altitude
+  phase difference between GCM and Tirvim (by 2-3 hours)
+  also compares during Global storm => larger amplitudes (up to 40k)
+
+Joseph:
+- will commit soon his last changes
+- started writing his paper

+
+News:
+====
+- NASA Ames will organize a training session on its legacy GCM

+==============
+- #81: some "call writediagfi" (vmr_xxx, num_xxx) end up skipped because
+  in an IF(callstats) section in physiq.
+
+Hot topics:
+===========
+
+* Improving the dust cycle (Antoine)
+- removed the "brighter dust" modification
+- test simulations with reduced mountain fraction for topflows
+- test simulation with lower maximum for dustradadjust (set to 3)
+In both cases gets warmer temperatures than before and the
+water cycle is better (due to changes in water albedo parameters)
+- thinking about issues due to the extrapolation of MCS profiles
+  when building column values in the dusty season. One could
+  think of adding a correction.
+- working on the MCs-normalization post-processing in the simulator
+  (to match integrated dust between MCS and GCM outputs)
+
+* Dynamico (Romain)
+- Tracer initialization in the start files now using the start-archive files
+  Still the model crashes after 0.5° of Ls
+
+Romain:
+- PEM: tests having substeps (of 1 year) in the extrapolation.
+  with a stop criterion (surface ice amount change) when change is too large
+
+Joseph:
+- preparing EPSC. Water cycle tuning with frost albedo.
+
+Aymeric:
+- work on improvement of the online MCD interface following the brainstorm session
+  last Monday.
+
+Lucas:
+- writing his internship report
+
+Margaux:
+- EPSC presentation about HDO modelling with comparisons with ACS.
+  GCM too wet overall. Too dry when supersaturation is removed.
+
+Siteng
+- Thermal tides EPSC presentation, comparisons between TIRVIM and GCM
+  Mode decomposition of the modes
+
+Thomas
+- bug in "seedout" in the MCD, at least with python interface
+
+Ehouarn
+- writing up a report for TAS-I on the LMD work done for ExoMars 2022 EDL
