+
+* Finalizing the DARI request for computing hours (deadline next Monday morning!):
+- For Mars: Goal: Finalizing GCM6 + producing MCD6
+  - CO2+water+dust cyle tuning (Antoine)
+  - non-oro GW (+possible orographic GW re-tuning) Jiandong
+  - CO2 clouds (Christophe => Lola + Anni) => 50kh ?
+  - GCM6 runs for MCD6 + validation (Ehouarn, Romain, Thomas) => 50kh?
+  - Dynamico + OpenMP work (Romain)
+  - other things?
+- For Paleo-Mars (past and ancient Mars): => PEM (Romain) + Lucas + Antony => ~400kh
+  - the work about adding sub-grid slopes (Lucas) can be included in this section
+
+* Improving the water and dust cycles (Antoine)
+- Ran simulations and checked that the non-conservation of water is ~0.2% per year
+  which is "reasonable" to proceed...
+- running with different albedos and thermal inertia (800 and 1500) of H2O ice deposit
+  gets a too dry water cycle in both cases. Now testing with lower albedos for ground ice and frost.
+- should commit the changes for dust cycle v6 to the trunk
+- wondering about making a "climatology" from MCS data over MYs to compare to the "clim" simulation
+
+* Non-orographic GW (Jiandong)
+- gets some polar warming which is closer to MCS obs
+- amplitude of the phase is improved but not perfect.
+- temperature field not affected below ~40km but winds are.
+
+* OpenMP:(Romain)
+- TBC
+
+Jean-Yves:
+- made comparisons of Deuterium density between GCM MY33 and MAVEN/IUS
+  D is overall underestimated by the GCM => due to missing ionospheric reactions for D ?
+  will discuss this with Francisco.
+
+Thomas:
+- the MCD web interface: is adding altitude of observer to spherical projections
+- working on slope wind model with simple model equation for theta

+- ACS SWT#13 yesterday and today (resumes at 1pm with Roland talking about Data Assimilation of TIRVIM,

+
+Hot topics:
+==========
+
+* Improving the water and dust cycles (Antoine)
+- tests water conservation over 10 sols; non-conservation is from the dynamics mostly
+  looked at total atmospheric mass evolution, not conserved in dynamics, even without CO2 condensation
+- tests renormalizing atmospheric mass/water at the beginning of the physics ongoing
+
+* Non-orographic GW (Jiandong)
+- TBC
+
+* OpenMP:(Romain)
+- TBC
+
+Thomas:
+- Slope winds in the MCD: changing the vertical distribution to be more uneven near the surface
+  improves things.
+- Some discussion about underlying hypothesis for evaluation of theta lower (surface) boundary condition.

+Bonjour,
+
+Ehouarn mentionned to me that he had not received last week Mars POULDP minutes... I was initially surprised but after checking, I realise that I only sent them to myself. No wonder ! Oh well. At last here are last weeks minutes :
+
+*****************************************
+
+Duration: 80 mn
+
+Participants: Lucas, Siteng, Romain, Christophe, Margaux, Thomas
+  Aymeric, Sandrine, Francois, Antony, Jiandong
+
+News:
+- Sandrine's TIRVIM paper is accepted, Siteng's TIRVIM paper is in
+  revision
+- Mars Atmosphere Workshop back in preparation..
+
+Recent commits: https://trac.lmd.jussieu.fr/Planeto/log
+==============
+Nothing new.
+
+Recent tickets: https://trac.lmd.jussieu.fr/Planeto/report/1
+==============
+- ticket about 32um emissivity: Christophe did add more information
+- ticket about initracer : christophe updated the ticket
+
+
+Various topics:
+==============
+
+* Thomas : designed a program to obtain the best parameters for his slope winds model. Show test results in various craters.
+
+- Problem with the comparison in Korolev because the topography is different in the MCD and in the mesoscale simulations used => Discussion : Aymeric realises that he made this simulation assuming a topography without ice glaciers during studies with Jack Holt...
+
+- Discussion : more levels could be used near the surface to optimize the wind calculations at 1 m.
+
+* Romain:
+Problem with crashes of the GCM at the very beggining of test runs after retarting the planetary evolution model.
+
+* Siteng Compare TIRVIM near-equatorial semidiurnal tide phase with GCM: when the observation sampling is taken into account, there is a difference up to 3 hours... The semidiurnal wavelength is also affected.
+
+* Christophe works on his papers. He has found a little bug in its simulation. Christophe is hoping to join Constantino Listowski's team at CEA (confirmation in one month). Would start on april 1st or may 1st.
+
+* Lucas :
+   - Work on the Planetary Evolution Model with Romain
+   - Work on water ice on slopes ("Debugging")
+
+* Jiandong :
+   - Tunes the Non-Oro Gravity Wave model to match temperatures.
+     Progresses are made
+
+* Antony
+   - Dynamico : We should meet and work on validation projects and science
+     projects with Dynamico => discussion this afternoon : let's wait for
+     the Mars GCM version 6
+
+* Francois
+   - Finishing the Insight paper as always.
+   - Will advertise two post-doc positions for the Mars Through Time
+     Project
