title: Convection embedded in an atmospheric river: exploring precipitation sensitivity to convective parameterizations

description: Atmospheric rivers (ARs) are major drivers of orographic precipitation along themountainous west coasts and often involve embedded convection delivering extreme localbursts of rainfall associated with flash floods. Understanding the convection within ARs iscritical for assessing flood risks and improving precipitation forecasts and numerical weathermodels. This study evaluates the sensitivity of the 2019 Valentine’s Day Atmospheric Riverprecipitation in California to Grell-Freitas and Tiedtke convective schemes using the WeatherResearch and Forecasting (WRF) model. Ensemble simulations at a 9 km horizontalresolution- a scale within the gray zone where some convection is resolved butparametrization remains necessary - are compared with seven observational datasets,including ground and satellite-based products. Over the ocean, WRF successfully captureskey synoptic features and the overall distribution of total precipitation due to the dominanceof stratiform precipitation. Convective precipitation, however, is simulated differently: Grell Freitas produces it within the AR, whereas Tiedtke simulates it west of the AR. Given thechallenges in diagnosing AR-embedded convection at 9 km, an alternative method based onoutgoing longwave radiation and precipitation rate thresholds is tested. The alternativeconvective precipitation aligns with observations, occurring within the AR over the ocean,coastal mountains, and Sierra Nevada. Using the alternative convective method, the overallpattern of convective precipitation is generally consistent between the Grell-Freitas andTiedtke schemes. This agreement contrasts with the patterns of parameterized convectiveprecipitation. These results are relevant for global models or regional large ensemblesapproaching gray zone resolution, guiding diagnostics of embedded convection in ARs.

title: Radio Astronomy with NASA's Deep Space Network

description: The Deep Space Network (DSN) is the spacecraft tracking and communication infrastructure for NASA's deep space missions. At three sites, approximately equally separated in (terrestrial) longitude, there are multiple radio antennas outfitted with cyrogenic microwave receiving systems both for receiving transmissions from deep space spacecraft and for conducting radio astronomical observations, particularly in the L~band (1350\,MHz--1800\,MHz), X~band (8200\,MHz--8600\,MHz), and K~band (18\,GHz--27\,GHz). In particular, the 70\,m antennas at the Canberra and Madrid DSN Complexes are well-equipped to participate in international very long baseline interferometery (VLBI) observations. Over the past five years, there has been an effort to refurbish and modernize equipment such as receiving and signal transport systems for radio astronomical observations. We summarize both current capabilities, on-going refurbishment activities, and include possible future opportunities.

title: Europa Clipper Mission Design: Interplanetary Trajectory Navigation Analysis

description: The Europa Clipper mission will explore Europa and investigate its habitability. The mission’s interplanetary trajectory includes flybys of Mars and Earth.We present a flight-path control analysis for navigating this portion of the mission. A summary of results is given to show that the mission for launch in 2024 can be navigated within the given propellant budget. The mission is also subject to requirements for planetary protection. In order to satisfy these requirements, the mission is limiting the probability of impact given failure after each TCM. This limit may be met by altering, or biasing, the trajectory. The biasing strategy is computed with the aid of a constrained minimization problem. The adopted biasing strategy implements biases which are the same for all the days of the launch period.

title: ClimaLand: A Land Surface Model Designed to Enable Data-Driven Parameterizations

description: Land surface models (LSMs) are essential tools for simulating the coupled climate sys27 tem, representing the dynamics of water, energy, and carbon fluxes on land and their in28 teraction with the atmosphere. However, parameterizing sub-grid processes at the scales 29 relevant to climate models (∼ 10–100 km) remains a considerable challenge. The pa30 rameterizations typically have a large number of unknown and often correlated param31 eters, making calibration and uncertainty quantification difficult. Moreover, many ex32 isting LSMs, written in legacy languages, are not readily adaptable to the incorporation 33 of modern machine learning parameterizations trained with in-situ and satellite data. 34 This article presents the first version of ClimaLand, a new LSM designed for overcom35 ing these limitations, including a description of the core equations underlying the model, 36 the results of an extensive set of validation exercises, and an assessment of the compu37 tational performance of the model. We show that ClimaLand can leverage graphics pro38 cessing units (GPUs) for computational efficiency, and that it’s modular architecture and 39 high-level programming language, Julia, allow for integration with machine learning li40 braries. In the future, this will enable efficient simulation, calibration, and uncertainty 41 quantification with ClimaLand.

title: WIde Separation Planets In Time (WISPIT): Two directly imaged exoplanets around the Sun-like stellar binary WISPIT 1

description: Context. Wide separation gas giant planets present a challenge to current planet formation theories, and the detection and characteri- sation of these systems enables us to constrain their formation pathways. Aims. The WIde Separation Planets In Time (WISPIT) survey aims to detect and characterise wide separation planetary-mass com- panions over a range of ages from &lt;5 to 20 Myr around solar-type host stars at distances of 75-500 (median 140) parsecs. Methods. The WISPIT survey carries out two 5 minute H-band exposures with the VLT/SPHERE instrument and IRDIS camera, separated by at least six months to identify co-moving companions via proper motion analysis. These two H-band observations in combination with a follow-up Ks-band observation were used to determine the colour-magnitude of the co-moving companions and to derive their masses by comparing to AMES-COND and AMES-DUSTY evolutionary tracks. Results. We report the discovery of WISPIT 1b and WISPIT 1c, two gas giant exoplanets that are co-moving with the stellar binary WISPIT 1, which itself consists of a K4 star and M5.5 star in a multi-decadal orbit. The planets are at projected separations of 338 au and 840 au and have masses of 10 MJ and 4 MJ, respectively. Conclusions. We identified two common proper motion planetary companions to a (previously unknown) stellar binary with a Sun- like primary. These targets are ideal for follow up characterisation with both ground and space-based telescopes. Monitoring of the orbit with the GRAVITY interferometer will place constraints on their eccentricity, and spectroscopic characterisation will identify the composition and metallicity, providing information on their formation pathways.

title: Euclid: An emulator for baryonic effects on the matter bispectrum★

description: The Euclid mission and other next-generation large-scale structure surveys will enable high-precision measurements of the cosmic matter distribution. Understanding the impact of baryonic processes such as star formation and active galactic nuclei (AGN) feedback on matter clustering is crucialto ensure precise and unbiased cosmological inference. Most theoretical models of baryonic effects to date focus on two-point statistics, neglectinghigher-order contributions. This work develops a fast and accurate emulator for baryonic effects on the matter bispectrum, a key non-Gaussianstatistic in the non-linear regime. We employ high-resolution 𝑁-body simulations from the BACCO suite and apply a combination of cutting-edgetechniques such as cosmology scaling and baryonification to efficiently span a large cosmological and astrophysical parameter space. A deep neuralnetwork is trained to emulate baryonic effects on the matter bispectrum measured in simulations, capturing modifications across various scalesand redshifts relevant to Euclid. We validate the emulator accuracy and robustness using an analysis of Euclid mock data, employing predictionsfrom the state-of-the-art FLAMINGO hydrodynamical simulations. The emulator reproduces baryonic suppression in the bispectrum to better than2% for the 68% percentile across most triangle configurations for 𝑘 ∈ [0.01, 20] ℎ/Mpc and ensures consistency between cosmological posteriorsinferred from second- and third-order weak lensing statistics. These results demonstrate that our emulator meets the high-precision requirementsof the Euclid mission for at least the first data release and provides forecasts of the cosmological and astrophysical information contained in thesmall-scale matter bispectrum. This underscores the potential of emulation techniques to bridge the gap between complex baryonic physics andobservational data, maximising the scientific output of Euclid.Key words.

title: Concept for a Venus Wind Energy Harvesting Platform for Long-Duration Power Generation

description: Venus, Earth’s closest twin planet is a mystery shrouded in cloud cover, whose surface secrets are defended by high pressure, oppressive heat, and a caustic environment. To learn more about this planet, it is necessary to have landers which operate on the surface of Venus, ideally for one diurnal cycle (120 earth-days) or longer. But any Venus mission targeting such a period of operation requires a sustained source of electrical power to make it through Venus’s 60-earthday- long night. Radioisotope power sources are not currently designed to work in Venus’s extreme temperature environment. Solar panels can operate at Venus temperatures, but Venus’s heavy cloud cover and long night would limit the power generated. Models predict there are multiple regions on Venus where the wind is strong and consistent throughout the day. By adapting and combining existing technologies, the Turbine-driven Venus Generator (TurVenAtor) would harvest wind power in these regions providing a sustained source of electrical power. TurVenAtor (Figure 1), would consist of a high-temperature permanent magnet synchronous generator (designed by Honeybee Robotics (HBR)), turbine blades and tail aerodynamics (designed at the California State University Los Angeles (CSULA)), and a system design, including a tower structure, azimuth gimbal, tail structure, blade material selection, and integration of the blades to the generator, which includes the turbine shaft and bearings (designed by the Jet Propulsion Laboratory (JPL)). To generate power, the turbine blades will turn the shaft, which is attached to a magnetic coupling, which transfers the rotation inside a pressurized can, which protects the gear train and generator components from the caustic environment. A tail and azimuthal gimbal keeps the turbine pointed into the wind, and the tower keeps the turbine at an elevated height. The outriggers prevent the turbine from tipping over. The generator would be tested in Venus temperature and pressure, the turbine blades in water as an analog to the dense atmosphere, and a final system level test would occur integrating all the components. The key innovations are using the existing HBR high-temperature motor design, but operating in reverse as a generator and CSULA using their analytical and empirical Interplanetary Turbine Design (ITD) process to optimize the blades for the low-speed, high-density Venus wind.

title: GNSS and InSAR integration for 3-D crustal deformation in California and western Nevada

description: The regions of California and Nevada are shaped by dynamic tectonic and hydrologic processes that drive significant crustal deformation. In this study we use the method of [Shen and Liu, 2020] to integrate Global Navigation Satellite System (GNSS) and Interferometric Synthetic Aperture Radar (InSAR) observations to investigate deformation from both tectonic and hydrologic activities. This method includes interpolating GNSS velocity data into a continuous velocity field, evaluating uncertainties in GNSS and InSAR measurements, correcting orbital errors in InSAR data, and combining InSAR Line-of-Sight measurements with GNSS data to resolve 3-D deformation using least-squares regression. We apply this method to three decades of GNSS and InSAR data across California and western Nevada. Key findings include: (1) Faulting along the San Andreas and Walker Lane fault systems drives dextral shear motions of 30–40 mm/yr and 8–12 mm/yr, respectively. Residual deformation, however, is broadly distributed within the fault systems, particularly in the Walker Lane region, suggesting contributions from ductile flow in the lower crust. (2) Significant subsidence, caused by drought and excessive groundwater withdrawal, is observed in the San Joaquin and Sacramento Valleys, at rates of 150-250 mm/yr and 10-25 mm/yr, respectively. Uplift rebound of 3-8 mm/yr is observed in the mountains surrounding the San Joaquin Valley. Notable subsidence of 6-12 mm/yr is also seen along the California coastline, while the Santa Maria Basin and Oxnard Plain experience subsidence of up to 15 mm/yr. (3) Abrupt vertical offsets are observed across various tectonically active faults, suggesting fault-modulated hydrological deformation.

title: Surface Mineralogy using Thermal InfraRed Spectroscopy Data from ECOSTRESS and ASTER

description: Mapping and managing Earth’s mineral resourcesdemands advanced techniques for characterizing surface composition,a challenge that can be effectively addressed by spaceborneEarth observation. Thermal infrared (TIR) sensors hosted onorbital platforms provide a powerful tool for regional scale(∼1000s km2), high-resolution (≤100m) identification of mineralcomposition and surface thermal properties. In this study, wedemonstrate the potential of multispectral TIR image dataacquired by the ECOSTRESS and ASTER spaceborne sensorswith near-global coverage to produce the first mineral maps ofthe Earth’s arid and semi-arid regions. TIR data complementVisible to ShortWave InfraRed (VSWIR) data because mostimportant rock forming minerals do not have features in theVSWIR. Thus, integrating TIR-derived mineralogy is essential tocomprehensively map the surface composition and interpret thegeology. The mapping results were validated at three sites—theAlgodones Dunes (quartz), White Sands Dunes (gypsum), andMehdi Ridge (calcite)—showing strong spatial and abundanceagreement with laboratory data from field samples and referenceliterature. These results confirm the reliability of high spatialresolution multispectral TIR data in capturing major surfacemineral distributions.

title: Signal Characteristics of Potential Airbursts in Titan's Atmosphere

description: We investigate the possibility of detecting airbursts in Titan's atmosphere by considering their burst characteristics (height and energy release) and associated overpressure and surface displacement. To simulate the airbursts, we track the progression of meteors through the atmosphere using the Separate Fragments Model. The Separate Fragments Model outputs an energy release curve that can be used to locate the burst height and estimate the energy associated with the airburst. The overpressure at the surface beneath the airburst is estimated using empirical equations derived for Earth based nuclear tests and adapted to other planetary atmospheres. We estimate the coupled seismic displacement as compliance eects from point source impulses at the atmosphere and surface boundary. We nd that the expected overpressure ranges between 1.1 53.2 Pa, and the peak velocity ranges between 0.1 and 72.3 µm/s, depending on the sur- face properties assumed for Titan. The larger signals may exceed the detection threshold of instrumentation onboard NASA's Dragony mission, namely the Dragony Meteorological suite (DraGMet). For the nominal Dragony mission lifetime of 3 years, our current estimates suggest that less than one meteor of radius 1 m or greater will impact Titan. This suggests that if positive detections of airbursts via pressure sensor or seismometer do occur, we may need to revise our understanding of the impactor population distribution in the outer solar system.
