title: Contribution of Rock Glacier Discharge to Late-Summer and Fall Streamflow in the Uinta Mountains, Utah, USA

description: Water draining from rock glaciers in the Uinta Mountains of Utah (USA) was analyzed and compared with samples of groundwater and water from the master stream in a representative 5000-ha drainage. Rock glacier water resembles snowmelt in the early summer, but evolves to higher values of d-excess and greatly elevated Ca and Mg content as the melt season progresses. This pattern is consistent with models describing a transition from snowmelt, to melting of seasonal ice, to melting of perennial ice in the rock glacier interior in late summer and fall. Water derived from this internal ice appears to have been the source of ~25% of the streamflow in this study area during September of 2021. This result emphasizes the significant role that rock glaciers can play in the hydrology of high-elevation watersheds, particularly in summers following a winter with below average snowpack

title: Analysis of NASA’s DSN Venus Express radio occultation data for year 2014

description: The Venus Express Radio Science Experiment (VeRa) was part of the scientific payload of the Venus Express (VEX) spacecraft and wastargeted at the investigation of Venus’ atmosphere, surface, and gravity field as well as the interplanetary medium. This paper describes themethods and the required calibrations applied to VEX-VeRa raw radio occultation selected data used to retrieve vertical profiles of Venus’ionosphere and neutral atmosphere. In this work we perform an independent analysis of a set of 25 VEX, single-frequency (X-band), occultationscarried out in 2014, recorded in open-loop at the NASA Deep Space Network. The calibrations are performed to correct the observed frequencyfor the major noise sources and errors, since any uncalibrated eects will bias the retrieval of atmospheric properties. We present a study on theinfluence of the relativistic eects on radio occultation of Venus. The temperature dierences between the relativistic and non-relativistic Dopplershift solutions are lower than 0.5 K at 50 km altitude, and our error analysis shows that, within this investigation, the relativity eects can safelybe neglected. Our temperature, pressure and electron density vertical profiles are in agreement with previous studies available in the literature.Furthermore, our analysis shows that Venus’ ionosphere is more influenced by the day/night condition than the latitude variations, while theneutral atmosphere experiences the opposite. Our scientific interpretation of these results is based on two major responsible eects: Venus’ highthermal inertia and the zonal winds. Their presence within Venus’ neutral atmosphere determine why in these regions a latitude dependence ispredominant on the day/night condition. On the contrary, at higher altitudes the two aforementioned eects are less important or null, and Venus’ionosphere shows higher electron density peaks in the probed day-time occultations, regardless of the latitude.

title: Datacube Parametrization-Based Model for Rough Surface Polarimetric Bistatic Scattering

description: A datacube parametrization-based model for bistatic scattering coefficient estimation and pattern reconstruction is presented in this work for electromagnetic wave scattering from rough surfaces with low to high subsurface dielectric constants. A datacube of bistatic scattering coefficients is simulated using the Stabilized Extended Boundary Condition Method (SEBCM). The polarization-combined bistatic scattering patterns of the datacube are fit with elliptical (or circular) contours that are parameterized across magnitude level, center location, and major axis length in normalized wavenumber space. These parameters depend on the surface roughness, dielectric contrast, as well as the angle of wave incidence. The polarimetric bistatic scattering patterns can be reconstructed through fast interpolation over the contours and projection onto the polarization unit vectors. Good agreement is achieved between the reconstructed bistatic scattering patterns compared with the original ones in the input datacube. Though not physics-based, this datacube parametrization-based model allows quick estimation and construction of the polarimetric bistatic scattering coefficients and patterns. The model development approach can also be adopted to parametrize datacubes from simulations with other configurations or targets, e.g., surface with different correlation functions, multilayer surfaces, surface covered with vegetation, etc.

title: CYGNSS FLOOD APPLICATIONS TO SUPPORT THE UNITED NATIONS SUSTAINABLE DEVELOPMENT GOALS

description: As climate change-induced global flooding increases in both frequency and magnitude, having accurate and timely flood maps becomes essential for humanitarian and future flood mitigation efforts. The Dartmouth Flood Observatory (DFO) aids humanitarian organizations and inundation observation research efforts through its archive of historical flood events extending back through 1985, as well as by providing current daily flood maps derived from a combination of observations, and also precipitation-based modeling products. Both could benefit from the addition of microwave observations that penetrate through clouds, rain, and vegetation, such as GNSS-R data now becoming available on a daily basis. In this work, we discuss a current collaboration to combine CYGNSS data with operational MODIS flood maps and evaluate the expected benefits for an example scenario over the recent anomalous flooding in South Sudan.

title: ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions – XV. Steady Accretion from Global Collapse to Core Feeding in Massive Hub-filament System SDC335

description: We present ALMA Band-3/7 observations towards “the Heart” of a massive hub-filament system (HFS) SDC335, to investigate its fragmentation and accretion. At a resolution of 0.03 pc, 3mm continuum emission resolves two massive dense cores MM1 and MM2, with 383¹¸234, and 120 𝑀sun  (10–24% mass of “the Heart”) and 74¸ 47, and 24 solar masses, respectively. With a resolution down to 0.01 pc, 0.87mm continuum emission shows MM1 further fragments into six condensations and multi-transition lines of H2CS provide temperature estimation. The relation between separation and mass of condensations at a scale of 0.01 pc favors turbulent Jeans fragmentation where the turbulence seems to be scale-free rather than scale-dependent. We use the H13CO¸ 𝐽 = 1 - 0 emission line to resolve the complex gas motion inside “the Heart” in position-position-velocity space.We identify four major gas streams connected to large-scale filaments, inheriting the anti-clockwise spiral pattern. Along these streams, gas feed the central massive core MM1. Assuming an inclination angle of 45¹ 15º  and a H13CO¸ abundance of 5¹ 3º   10􀀀11, the total mass infall rate is estimated to be 2.40¹ 0.78º   10􀀀3 𝑀  yr􀀀1, numerically consistent with the accretion rates derived from the clump-scale spherical infall model and the core-scale outflows. The consistency suggests a continuous, near steady-state, and efficient accretion from global collapse, therefore ensuring core feeding. Our comprehensive study of SDC335 showcases the detailed gas kinematics in a prototypical massive infalling clump, and calls for further systematic and statistical studies in a large sample.

title: (523599) 2003 RM; The Asteroid That Wanted To Be a Comet

description: We report a statistically signicant detection of nongravitational acceleration on the sub-kilometer near-Earth asteroid (523599) 2003 RM. Due to its orbit, 2003 RM experiences favorable observing apparitions every 5 years. Thus, since its discovery, 2003 RM has been extensively tracked with ground-based optical facilities in 2003, 2008, 2013, and 2018. We nd that the observed plane-of-sky positions cannot be explained with a purely gravity-driven trajectory. Including a transverse non gravitational acceleration allows us to match all observational data, but its magnitude is inconsistent with perturbations typical of asteroids such as the Yarkovsky eect or solar radiation pressure. After ruling out that the orbital deviations are due to a close approach or collision with another asteroid, we hypothesize that this anomalous acceleration is caused by unseen cometary outgassing. A detailed search for evidence of cometary activity with archival and deep observations from Pan-STARRS and the VLT does not reveal any detectable dust production. However, the best-tting H2O sublimation model allows for brightening due to activity consistent with the scatter of the data. We estimate the production rate required for H2O outgassing to power the acceleration, and nd that, assuming a diameter of 300 m, 2003 RM would require Q(H2O) 1023 molec/s at perihelion. We investigate the recent dynamical history of 2003 RM and nd that the object most likely originated in the mid-to-outer main belt ( 86%) as opposed to from the Jupiter-family comet region ( 11%). Further observations, especially in the infrared, could shed light on the nature of this anomalous acceleration.

title: A physical explanation for ocean air-water warming differences under CO2-forced warming

description: Modelled global warming is often quantified using global near-surface air temperature (T_as). Meanwhile, long-term temperature datasets combine observations of Tas over land with sea-surface temperature (SST) over ocean. Modelled ocean Tas warms more than SST, which can bias model-observation comparisons. Skin temperature (Ts), which is typically warmer than Tas, follows SST changes so the ocean surface temperature discontinuity δT_s=T_s-T_as decreases with warming. Here I show that under CO2 forcing, decreased δT_s is consistently simulated for nonpolar ocean within ±60 °S/N, but not for other regions. I investigate the causes of oceanic δT_s decrease using aLongRunMIP climate simulation, radiative kernels, and standard methods for diagnosing forcing and feedbacks from the CMIP5 ensemble. CO2 forcing establishes longwave heating of the lower atmosphere and subsequent adjustments that result in a small Tas increase, and therefore δT_s decrease. During the subsequent warming in response to CO2 forcing, the model-mean surface evaporation feedback is 3.6 W m-2 °C-1 ¬over oceans, which reduces Ts warming relative to Tas and further shrinks δT_s. Present day forcing and feedback contributions are of similar magnitude, and both contribute to small differences in model-observation comparisons of global warming rates when these differences are not accounted for.

title: A Map Relative Localization System for Planetary Landing

description: The Mars 2020 Entry Descent and Landing (EDL) system successfully delivered the Perseverance rover to the surface of Mars on February 18th, 2021. A large fraction of the 8km wide Jezero Crater landing ellipse is covered with landing hazards including cliffs, inescapable dune fields and rocks. To mitigate the risk of these hazards, a novel Terrain Relative Navigation system was developed and integrated with the heritage Mars Science Laboratory EDL system. First the hazards were identified or inferred using orbital imagery and stored on-board the spacecraft as a hazard map. During parachute descent, the Lander Vision System (LVS) estimated map relative position by fusing landmarks matched between descent imagery and a map of the landing site with inertial measurement unit data. This position estimate and the hazard map were used by the powered descent guidance and control system to identify and then fly to the safest target for landing that was also reachable given fuel and other constraints. Post-flight analysis indicated that the horizontal error between the targeted location and actual landing location was 5m relative to a 60m requirement, which indicated that all required systems worked much better than designed. In particular, the fully autonomous LVS generated a position estimate in 10s that was in error by only a few meters relative to a 40m requirement. This paper describes the LVS design, how it was tested before launch and the LVS performance during EDL.

title: Error and Uncertainty Degrade Topographic Corrections of Remotely Sensed Data

description: Chemical and biological composition of surface materials and physical structure and arrangementof those materials determine the intrinsic reflectance of Earth's land surface. The apparent reflectance—asmeasured by a spaceborne or airborne sensor that has been corrected for atmospheric attenuation—depends alsoon topography, surface roughness, and the atmosphere. Especially in Earth's mountains, estimating propertiesof scientific interest from remotely sensed data requires compensation for topography. Doing so requiresinformation from digital elevation models (DEMs). Available DEMs with global coverage are derived fromspaceborne interferometric radar and stereo-photogrammetry at ∼30 m spatial resolution. Locally or regionally,lidar altimetry, interferometric radar, or stereo-photogrammetry produces DEMs with finer resolutions.Characterization of their quality typically expresses the root-mean-square (RMS) error of the elevation, butthe accuracy of remotely sensed retrievals is sensitive to uncertainties in topographic properties that affectincoming and reflected radiation and that are inadequately represented by the RMS error of the elevation. Themost essential variables are the cosine of the local solar illumination angle on a slope, the shadows cast byneighboring terrain, and the view factor, the fraction of the overlying hemisphere open to the sky. Comparisonof global DEMs with locally available fine-scale DEMs shows that calculations with the global productsconsistently underestimate the cosine of the solar angle and underrepresent shadows. Analyzing imagery ofEarth's mountains from current and future spaceborne missions requires addressing the uncertainty introducedby errors in DEMs on algorithms that analyze remotely sensed data to produce information about Earth's surface.

title: Permafrost Dynamics Observatory (PDO) – Part II: Joint Retrieval of Permafrost Active Layer Thickness and Soil Moisture from L-band InSAR and P-band PolSAR

description: Seasonal subsidence induced by ground ice melt can be measured by interferometric synthetic aperture radar (InSAR) techniques to infer active layer thickness (ALT) in permafrost regions. The magnitude of subsidence depends on both how deep the soil thawed and how much ice/water content existed in the active layer soil. To provide the later, P-band polarimetric synthetic aperture radar (PolSAR) backscatter is used due to its sensitivity to subsurface soil moisture and freeze/thaw conditions. In this study, which is the second in a two-part series of Permafrost Dynamics Observatory (PDO), we exploit L-band InSAR subsidence and P-band PolSAR backscatter in a joint retrieval scheme to simultaneously estimate ALT and soil moisture profile of permafrost active layer. Both subsidence and backscatter are explicitly characterized by physics-based models and share a common set of soil parameters including porosity and water saturation profiles. The PDO joint retrieval has been applied to the L- and P-band SAR data acquired by NASA/JPL’s Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) over Alaska and western Canada during the 2017 Arctic-Boreal Vulnerability Experiment (ABoVE) airborne campaign. This high-resolution (30 m) regional estimates of ALT and soil moisture profile spanning over the ABoVE study domain can help link the ground-based field surveys with satellite observations to further understand the permafrost and active layer soil process dynamics to disturbances and climate change occurring across the northern circumpolar region.

title: A Half Century of Formal Methods

description: In this '45 Years of Formal Methods' review we first delineate what we mean by method, formal method, computer science, computing science, software engineering, and model-oriented and algebraic methods. Based on this we shall characterise a spectrum from specification-oriented methods to analysis-oriented methods. Then we shall provide an Overview: which are the `prerequisite works' that have enabled formal methods; and which are, to us, the, by now, classical formal Specification and Analysis Methods. We then ask ourselves the question: A Success Story? Have formal methods for software development, in the sense of this paper been successful? Our answer is a guarded yes. At the start of More Personal Observations, we relate, in The DDC Ada Story, a 1980--1984 formal methods success story. We motivate the guarded answer by discussing Some Obstacles to Formal Methods in university research and education as well as in industry practice. Finally we discuss current programming language developments in a Next 10 Years perspective. Although some of these trends have occurred in parallel with formal methods development, and seemingly independent thereof, we do see some convergence.
