General introductionThe Mars Climate Database (MCD) is a database of meteorological fields derived from Circulation Model (GCM) numerical simulations the Martian atmosphere using Planetary (PCM) and validated available observational data. The MCD includes complementary post-processing schemes such as high spatial resolution interpolation environmental data means reconstructing variability thereof [1].The latest version MCD, 6.1, was released in December 2022. The PCM (formerly known...
The degradation in electrical output of solar arrays on Mars landers and rovers is reviewed. A loss 0.2% per Sol typical, although observed rates decrease 'dust factor' vary between 0.05% 2% Sol. 0.2%/Sol has been throughout the first 800 Sols ongoing InSight mission, as well shorter Pathfinder Phoenix missions. This rate was also evident for much Spirit Opportunity missions, but there episodically reversed by cleaning events due to dust devils gusts. enduring success those rover missions...

Abstract In this paper, the non‐orographic gravity waves (GW) parameterization of Mars Planetary Climate Model (PCM) previously implemented by Gilli et al. (2020, https://doi.org/10.1029/2018JE005873 ) is revisited and extended to exobase (∼250 km). The simulations performed with new scheme correct some known biases in modeled thermal tide amplitudes polar warming, improving agreement Sounder (MCS) observed structures tides below ∼100 km. Additionally, we find that simulated densities above...
The rate of occurrence High Frequency (HF) marsquakes, as recorded by InSight at Homestead Hollow, Elysium Planitia, increased after about LS=33∘, and ceased almost completely LS=187∘, following an apparently seasonal variation with a peak near aphelion. We define seismic models based on the declination Sun, annual solar tides, CO2 cycle measured atmospheric pressure. Evaluation Akaike weights evidence ratios shows that Sun is most likely, least likely driver this activity, although...
Recent simulations of the Institut Pierre-Simon Laplace (IPSL) Venus Global Climate Model (VGCM) developed at Laboratoire de Météorologie Dynamique (LMD) were performed with a model top raised from ∼10−5 (∼150 km) to ∼10−8 Pa (180–250 km; upper boundary). The parameterizations non-LTE CO2 near infrared heating rates and non-orographic gravity waves improved. In addition, tuning atomic oxygen production was introduced improve related effects (heating cooling) resulting thermospheric number...
Introduction: The Venus Climate Database (VCD) is a free tool designed to be useful for engineers and scientists in need of reference atmosphere mission planning, observations preparation, analysis interpretation. VCD atmospheric fields are based on outputs from simulations using the Planetary Model (V-PCM) [1,2]. This project funded by European Space Agency, frame EnVision Venus. currently distributed version 2.3.Overview Database: provides mean values statistics main meteorological...
A main goal in the field of statistical shape analysis is to define computable and informative metrics on spaces immersed manifolds, such as space curves a Euclidean space. The approach taken elastic framework metric by starting with reparameterization-invariant Riemannian parameterized shapes inducing quotient group diffeomorphisms. This computed, practice, finding registration two over diffeomorphism group. For curves, initial frequently chosen from two-parameter family Sobolev metrics,...

In this paper, we revisit the notion of length measures associated to planar closed curves. These are a special case area hypersurfaces which were introduced early on in field convex geometry. The measure curve is circle $\mathbb{S}^1$ that intuitively represents portion tangent vector points certain direction. While not characterized by its measure, fundamental Minkowski-Fenchel-Jessen theorem states fully characterize curves modulo translations, making it particularly useful tool study...
<p>For fifteen years, a Global Climate Model (GCM) has been developed for the Venus atmosphere at “Institut Pierre-Simon Laplace” (IPSL), in collaboration between LMD and LATMOS, from surface up to 150 km altitude (Lebonnois et al., 2010; 2016). Recently, vertical grid was extended 10<sup>-5</sup> Pa 10<sup>-8</sup> (~180-250 km) allows us simulate Venusian upper thermosphere. At same time,...
