+Duration: 1h

+Participants: Romain, Ehouarn, Joseph, Antoine, Siteng, Thomas, Francois, Lucas
+
+News:
+====
+- Jiandong Liu will start his year long postdoc at LMD on Wednesday September 8th.
+- We will have to start organizing MAMO (and EMM meeting in the following week)
+
+Recent commits: https://trac.lmd.jussieu.fr/Planeto/log
+==============
+- r2554: Make NO and O2 Nightglow emissions computations more flexible
+         (indexes no longer hard coded)
+- r2555: added arch files and IOIPSL install script for Irene-Rome
+
+Recent tickets: https://trac.lmd.jussieu.fr/Planeto/report/1
+==============
+- None.
+  But from Gitlab Issues #23 by Gabriella:
+  some "call writediagfi" (vmr_xxx, num_xxx) end up skipped because
+  in an IF(callstats) section in physiq.
+
+Hot topics:
+===========
+
+* Dynamico (Romain)
+- Test with low resolution work well. Now testing higher resolution (nbp=40) but crashes after a couple of days
+  Most likely linked to the initialization of tracers.
+
+* Improving the dust cycle (Antoine)
+- comparisons with ACS dust (and ice) profiles at low latitudes.
+  Looks at the impact of the injected dust radius.
+  ACS (quite noisy looking profiles...) sees high radius near the surface ~ 2um ,
+  and detached layers at ~20 km
+  Injection in the GCM of 3um dust works less well than using 2.5um
+  Will test this configuration for other Mars years / scenarios.
+
+Siteng:
+- Thermal tides study with TIRVIM. Focused on MY35 Ls~100, LT 9am/9pm
+  Looks at the dayly anomaly in data and GCM+averaging kernels
+  Decomposition in various wave modes. reasonable agreement between data and GCM
+  Impact of the sampling on the decomposition can be significant
+
+Thomas:
+- looking with Antoine at the MCD web interface: let's meet to discuss about some improvement
+  next Monday 4pm or Wednesday 4pm? (if Aymeric is also available)
+- finished the MCD6.1 beta ready to be delivered to ESA.
+
+Joseph:
+- just back from vacation. Has lots of commits to make in the near future.
+
+Lucas:
+- working on EPSC presentation and has a first draft of a paper on CO2 caps evolution
+
+Romain:
+- Planetary Evolution Model: in-between GCM simulations interpolation with a
+  time step of 100 years. Finds local accumulation (with strongly unequilibrated
+  initial conditions). Tests using 3 GCM simulated years rather than 2.
+  Also needs to investigate how to constrain physically the extrapolation step.
+
+Francois:
+- Will be looking for 2 postdocs for "Mars through Time" in the coming months.

+
+News:
+====
+- Summer break: no more POULDP Mars until 26th of August!
+- GENCI A11 call (deadline sept 3rd), we will request access to TGCC for the extra
+  computation time, and test GCMs run fine on Irene-Rome in the Summer.
+
+Recent commits: https://trac.lmd.jussieu.fr/Planeto/log
+==============
+- r2544: fix calendar when outputing multiple time steps in restart
+- r2545: output tab_cntrl with XIOS
+- r2546: adapt utilities concat/localtime/zrecast to XIOS files
+- r2547: update deftank reference xml files
+- r2551: undo unwanted changes in physiq from 2545
+
+Recent tickets: https://trac.lmd.jussieu.fr/Planeto/report/1
+==============
+- #79: check if run.def is there and stop if not
+- #80: zrecast should spot if "pressure" (or other field) is requested twice
+>> Add "area" to zrecast outputs (Francois)
+
+Hot topics:
+===========
+* Time keeping in the start files
+Should be solved (waiting for Roland's feedback, just in case)
+
+* Dynamico (Romain)
+- the water cycle is now reasonable.
+- comparisons with MCS temperatures are promising (better in polar regions than LMDZ).
+- winds are quite different between LMDZ and dynamico.
+
+* Improving the Dust Cycle (Antoine)
+- TBC
+
+Thomas:
+- slope winds parametrization for MCD: comparisons with HR mesoscale simulations
+  around Korolev: fails to well reproduce slope winds during the day.
+
+Siteng:
+- correcting for the seasonal change using GCM outputs doesn't work well
+- at 10 Pa the model is overall cooler (~5-10K) than obs.
+
+Lucas:
+- surface pressure comparisons with landers. MSL deficit around Ls 180-270.
+  mesocale prediction better than GCM (local circulation effects?); but
+  differences also at Insight landing site.
+
+Margaux:
+- comparing GCM and ACS data (H2O) from Anna, during the storm, more high altitude
+  H2O in the GCm than in the observations.

+=> suggestion (Antoine): improve zrecast when user requests "pressure" which is also computed.
+=> in some cases (Romain) the model crashes/stops but job continues until killed
+=> when run.def is missing, the model should stop with a clean error message.
+
+
+Hot topics:
+===========
+
+* Time keeping in the start files
+Romain made the modifications & test and will commit.
+
+* Dynamico
+Romain: Too dry dynamico => the problem was in the initial conditions in startfi.nc
+Fixes the problem for the beginning of the year. But way too much water is second half of year.
+Checked that water is globally conserved until month #9, where watercaptag decreases in the south
+
+* Improving the Dust Cycle
+Antoine: looking at ACS data around global dust storm of MY34 (paper by M. Luginin and Anna Fedorava )
+and will compare mass loading and effective radius with those computed by the GCM.
+Plans to zrecast (high vertical resolution) or maybe use "profiles" utility
+
+Siteng:
+Sees large seasonal changes in the tides
+Sharp change at the rim of Hellas in the waves from model.
+Looks at substracting the seasonal effect from the tides.
+
+Christophe:
+Negative values of h2o_ice at he surface: re-ran 5 years from scratch, no negative values
+But water cycle clearly not converged yet.

+=====
+Roland Young is looking for a postdoc https://rolandyoung.bitbucket.io/601471.pdf
+
+
+Recent commits: https://trac.lmd.jussieu.fr/Planeto/log
+==============
+- r2550: Make simu_MCS.F90 compatible with DYNAMICO lon-lat output files, with a check on the latitude array order when doing the interpolation
+- r2551:  Add possibility of additional tests (NaNs?, but also of unrealistic values) of fields at the begining of physics (i.e. coming from the dynamics) and at the
+                 end of the physics integration

+
+Ongoing discussions:
+===================
+
+- Romain : did some comparison between DYNAMICO-LMDZ-MCS : tsurf seems similar between DYNAMICO-LMDZ
+                   some difference in wind between DYNAMICO and LMDZ, could it be the sponge layer?
+                   big difference in water cycle: dryer in DYNAMICO than LMDZ, why?
+
+- Siteng: continue to work on diurnal cycle in the observations, difference at 15 h local time between GCM and obs
+
+- Antoine : work on dust cycle to match with MCS temperature, added the Joseph water, improvements are in the good way
+
+- Thomas : new version of MCD 6.1.alpha: slop winds in high resolution mode.
+                    Good agreements between mesoscale and MCD on winds
+                    Delivery soon
+
+- Christophe : new work on co2clouds => debugging step
