title: Surface Accessibility with Vertical Controlled Landing on 67P / Churyumov-Gerasimenko

description: With the increasing interest of small body science due to its important role in the puzzle of the solar system formation, missions to small bodies are studied and developed in preparation for future exploration. Together with the operational experience gained and the general rapid technology development, landers and 5 surface mobility elements enable more and more an enhancement of the scientific mission return by collecting in-situ measurements or samples of the surface. Hence, the descent and landing operations become a vital part in a successful execution of the mission. In this paper, a descent strategy for a vertical landing on small bodies is 10 presented. A controlled descent and landing sequence is proposed as opposed to ballistic descents used in previous small body landers [1]. The analysis aims for a generic investigation of the surface accessibility of a small body on the example of the comet 67P / Churyumov-Gerasimenko. A vertical controlled descent trajectory concept is proposed and applied to all surface facets of the 15 downscaled ESA polyhedron shape model (released in 2015 [2]). The trajectories are assessed by their duration of descent, ∆v need and their surface accessibility with respect to safety distances to the surface and the canyon walls. The analysis results in ∆v need ranges between ∆vmin = 0.7 m s−1 and ∆vmax = 3.1 m s−1 , the duration of descent between tmin = 65 min and tmax = 20 275 min. If a minimum distance of 175 m to the canyon surface or walls is considered as safe, 90 % of the comet’s surface is accessible with the implemented strategy

title: Understanding of Contemporary Regional Sea-level Change and the Implications for the Future

description: Global sea level provides an important indicator of the state of the warming climate, but changes in regional sea level are most relevant for coastal communities around the world. With improvements to the sea-level observing system, the knowledge of regional sea-level change has advanced dramatically in recent years. Satellite measurements coupled with in situ observations have allowed for comprehensive study and improved understanding of the diverse set of drivers that lead to variations in sea level in space and time. Despite the advances, gaps in the understanding of contemporary sea-level change remain, and inhibit the ability to predict how the relevant processes may lead to future change. These gaps arise in part due to the complexity of the linkages between the drivers of sea-level change. Here, we review the individual processes which lead to sea-level change, and then describe how they combine and vary regionally. The intent of the paper is to provide an overview of the current state of understanding of the processes that cause regional sea-level change, and to identify and discuss limitations and uncertainty in our understanding of these processes. Areas where the lack of understanding or gaps in knowledge inhibit the ability to provide the needed information for comprehensive planning efforts are of particular focus. Finally, a goal of this paper is to highlight the role of the expanded sea-level observation network – particularly as related to satellite observations – in the improved scientific understanding of the contributors to regional sea-level change.

title: The Gaia Ultra-Cool Dwarf Sample - III: Seven new multiple systems containing at least one Gaia DR2 ultra-cool dwarf.

description: We present ten new ultra-cool dwarfs in seven wide binary systems discovered using Gaia DR2 data, identied as part of our Gaia Ultra-Cool Dwarf Sample project. The seven systems presented here include an L1 companion to the G5 IV star HD 164507, an L1: companion to the V478 Lyr AB system, an L2 companion to the metal-poor K5V star CD-28 8692, an M9V companion to the young variable K0V star LT UMa, and three low-mass binaries consisting of late Ms and early Ls. The HD 164507, CD- 28 8692, V478 Lyr, and LT UMa systems are particularly important benchmarks, because the primaries are well characterised and oer excellent constraints on the atmospheric parameters and ages of the companions. We nd that the M8V star 2MASS J23253550+4608163 is 2.5 mag overluminous compared to M dwarfs of sim- ilar spectral type, but at the same time it does not exhibit obvious peculiarities in its near-infrared spectrum. Its overluminosity cannot be explained by unresolved binarity alone. Finally, we present an L1+L2 system with a projected physical separation of 959 au, making this the widest L+L binary currently known.

title: Defining Knowledge Workers’ Creation, Description, and Storage (CDS) Practices as Impact on Enterprise Content Management Strategy

description: As part of the effort to digitally transform, organizations are seeking more and better solutionsto longstanding enterprise content management challenges. Such solutions rarely investigatethe relationship between knowledge workers’ daily work to capture information and theperceived or actual value of that information to the enterprise per established contentmanagement strategy. The study described in this paper seeks to identify gaps in contentmanagement practices versus policy by modeling the conventions by which one organization'sknowledge workers typically generate, store, and later recover their daily work products. Thirty-fiveinterviews with knowledge workers at the Jet Propulsion Laboratory were conducted onthis subject. The results of these interviews provide an insight as to how knowledge workersinteract with enterprise content in their dual roles as both the primary creators and primaryconsumers of enterprise content. This paper, which outlines various permutations of the digitalobject creation, description, and storage (CDS) model, provides basic strategies for bringing thevalue perceptions of knowledge workers into alignment with institutional directives related toimproving content findability and reuse in the enterprise.

title: Recent Amplified Global Gross Primary Productivity Due to Temperature Increase is 1 offset by Reduced Productivity Due to Water Constraints

description: Satellite remote sensing observations show an increased greenness trend over land in recent decades. While greenness observations can indicate increased productivity, estimation of total annual productivity is highly dependent on vegetation response to climate and environmental conditions. Models have been struggling to determine how much carbon is taken up by plants as a result of increased atmospheric CO2 fertilization. Current remote sensing light use efficiency (LUE) models contain considerable uncertainty due to the lack of spatial and temporal variability in maximum LUE parameter and climate sensitivity defined for global plant functional types (PFTs). We used the optimum LUE (LUEopt) previously derived from the global FLUXNET network to improve estimation of global gross primary productivity (GPP) for the period 1982–46 2016. Our results indicate increasing GPP in northern latitudes owing to reduced cold temperature constraints on plant growth, thereby suggesting increasing negative carbon-climate feedback in high latitudes. In the tropics, by contrast, our results indicate an emerging positive climate feedback, mainly due to increasing atmospheric vapor pressure deficit (VPD). Further pervasive VPD increase is likely to continue to reduce global GPP and amplify carbon emissions.

title: Designing Low-Thrust Trajectories for a SmallSat Mission to Sun-Earth L5

description: Asmall satellite deployed to Sun-Earth L5 could serve as a low-cost platform to observe solar phenomena. However, the small satellite form factor introduces significant challenges into the trajectory design process via limited thrusting capabilities, power and operational constraints, and fixed deployment conditions. To address these challenges, a strategy employing dynamical systems theory is used to design a trajectory for a low-thrust enabled small satellite to reach the Sun-Earth L5 region. This procedure is demonstrated for a small satellite that launches as a secondary payload with a larger spacecraft that is destined for a Sun-Earth L2 halo orbit. Lowthrust trajectories, delivering the spacecraft from a deployment condition in the Earth vicinity to an L5 science orbit, are produced for both an ESPA-class SmallSat and a 6U CubeSat. These solutions demonstrate the value of a dynamical systems approach to trajectory design, while also supporting the potential for small satellite missions to perform targeted heliophysics-based scientific observations well beyond low Earth orbit.

title: The Polarimetric Sensitivity of SMAP-Reflectometry Signals to Crop Growth in the US Corn Belt

description: Crop growth is an important parameter to monitor in order to obtain accurate remotely sensed estimates of soil moisture, as well as assessments of crop health, productivity, and quality commonly used in the agricultural industry. The Soil Moisture Active Passive (SMAP) mission has been collecting Global Positioning System (GPS) signals as they reflect off the Earth’s surface since August 2015. The L-band dual-polarization reflection measurements enable studies of the evolution of geophysical parameters during seasonal transitions. In this paper, we examine the sensitivity of SMAP-reflectometry signals to agricultural crop growth related characteristics: crop type, vegetation water content (VWC), crop height, and vegetation opacity (VOP). The study presented here focuses on the United States “Corn Belt,” where an extensive area is planted every year with mostly corn, soybean, and wheat. We explore the potential to generate regularly an alternate source of crop growth information independent of the data currently used in the soil moisture (SM) products developed with the SMAP mission. Our analysis explores the variability of the polarimetric ratio (PR), computed from the peak signals at V- and H-polarization, during the United States Corn Belt crop growing season in 2017. The approach facilitates the understanding of the evolution of the observed surfaces from bare soil to peak growth and the maturation of the crops until harvesting. We investigate the impact of SM on PR for low roughness scenes with low variability and considering each crop type independently. We analyze the sensitivity of PR to the selected crop height, VWC, VOP, and Normalized Differential Vegetation Index (NDVI) reference datasets. Finally, we discuss a possible path towards a retrieval algorithm based on Global Navigation Satellite System-Reflectometry (GNSS-R) measurements that could be used in combination with passive SMAP soil moisture algorithms to correct simultaneously for the VWC and SM effects on the electromagnetic signals.

title: Stable rate of slip along the Karakax Valley Fault from observation of inter-glacial and post-glacial offset morphology and surface dating

description: Digital elevation maps obtained using TanDEM-X and Pleiades data combined with newly23 obtained surface age estimates using Cosmogenic Radionuclide (CRN) and Optically Sim24 ulated Luminescence (OSL) methods are used to quantify the slip-rate along the west25 ern section of the Altyn Tagh fault in southern Xinjiang. The reconstruction of the con26 ical shape of massive alluvial fans inferred to be from the Eemian (115±7 ka) from CRN27 dating shows consistent left-lateral offsets of 300±20 m, yielding a slip rate of 2.6±0.328 mm/yr. Successive episodes of incision have left cut terraces inset in wide canyons, 10-29 25 m below the fans’ surface. The incision was followed by the deposition of a broad ter30 race of early Holocene age, which is re-incised by modern stream channels. Near the vil31 lage of Shanxili, a 200 m-wide valley is partially dammed by a shutter ridge displaced32 by the fault. A fill terrace deposited upstream from the ridge has an OSL age of 8.8±0.633 ka. The 23±2 m offset of the riser incising the terrace indicates a minimum post-depositional34 movement on the fault, yielding a Holocene rate of 2.6±0.5 mm/yr, consistent with the35 115 ka-average slip rate. Scarp degradation analysis using mass diffusion reveals a non36 linear relationship between fault displacement and degradation coefficient along the pro37 gressively exposed fault scarp, a pattern suggesting either seismic clustering or variable38 diffusion rate since the Eemian. Together with the Gozha Co-Longmu Co fault to the39 south, the Karakax section of the Altyn Tagh Fault contributes to the eastward move40 ment of the western corner of Tibet.

title: Bayesian Model Averaging of Climate Model Projections Constrained by Precipitation Observations over the Contiguous United States

description: This study utilizes Bayesian Model Averaging (BMA) as a framework to constrain the spread of uncertainty in climate projections of precipitation over the contiguous United States (CONUS). We use a subset of historical model simulations and future model projections (RCP8.5) from the Coupled Model Intercomparison Project Phase 5 (CMIP5). We evaluate the representation of five precipitation summary metrics in the historical simulations using observations from theNASA Tropical Rainfall Measuring Mission (TRMM) satellites. The summary metrics includemean, annual and interannual variability, and maximum and minimum extremes of precipitation. The estimated model average produced with BMA is shown to have higher accuracy in simulating mean rainfall than the ensemble mean (RMSE of 0.49 for BMA vs 0.65 for ensemble mean), and a more constrained spread of uncertainty with roughly a third of the total uncertaintythan is produced with the multi-model ensemble. The results show that, by the end of the century, the mean daily rainfall is projected to increase for most of the East Coast and the Northwest, may decrease in the Southern US, and with little change expected for the Southwest. For extremes, the wettest year on record is projected to become wetter for the majority of CONUS and the driest year to become drier. We show that BMA offers a framework to more accurately estimate and to constrain the spread of uncertainties of future climate, such as precipitation changes over CONUS.
