title: Data and Code for: Self-Preferencing at Amazon: Evidence from Search Rankings

description: We study whether Amazon engages in self-preferencing on its marketplace by favoring its own brands (e.g., Amazon Basics) in search. To address this question, we collect new micro-level consumer search data using a custom browser extension installed by a panel of study participants. Using this methodology, we observe search positions, search behavior, and product characteristics. We find that Amazon branded products are indeed ranked higher than observably similar products in consumer search results. The prominence given to Amazon brands is 30% to 60% of the prominence granted to sponsored products.

title: The search for radio emission from the exoplanetary systems 55 Cancri, Andromedae, and Boötis using LOFAR beam-formed observations

description: Context. The detection of radio emissions from exoplanets will open up a vibrant new research field. Observing planetary auroral radio emission is the most promising method to detect exoplanetary magnetic fields, the knowledge of which will provide valuable insights to the planet’s interior structure, atmospheric escape, and habitability. Aims. Here, we present LOFAR-LBA low-frequency circularly polarized beamformed observations of the three exoplanetary systems 55 Cancri, υ Andromedae, and τ Boötis. All three systems are predicted to be good candidates to search for exoplanet radio emission. Methods. We apply the BOREALIS pipeline that we have developed to mitigate radio frequency interference and search for both slowly varying and bursty radio emission. Our pipeline has been quantitatively benchmarked on attenuated Jupiter radio emission. Results. We detect circularly polarized bursty emission from τ Boötis b in the range 14-21 MHz with a flux density of ∼430 mJy with a statistical significance ∼3σ. For this detection, obtained with the method that we benchmarked on Jupiter bursts, we identified no potential false positives. Also, we tentatively find slowly variable emission from τ Boötis in the range 21-30 MHz with a flux density of ∼400 mJy with a statistical significance of ∼8.6σ. This emission is circularly polarized, structured in the time-frequency plane, and in excess in the ON-beam with respect to the two simultaneous OFF beams. However, close examination of the observed signature casts some doubts about the reality of the signal. We discuss in detail all the arguments for and against an actual detection, and derive from that methodological tests and conclusions that will apply to future searches. Conclusions. Assuming that these circularly polarized emissions are real and generated through the cyclotron maser mechanism, we can derive limits on the range of the polar surface magnetic field strengths for the planet τ Boötis b. No signal is detected from the 55 Cancri system, on which we place a 3σ upper limit of 73 mJy for the flux density at the time of the observation. Also, no signal is found from the υ Andromedae system with the exception of a ∼2σ marginal signal on one observation of bursty emission in the range 14-38 MHz. Further observations with LOFAR and other low-frequency telescopes such as NenuFAR or UTR-2 are required to confirm these possible first detections of exoplanetary radio signals. Key words.

title: Long-term (1999-2019) variability of stratospheric aerosol over Mauna Loa, Hawaii, as seen by two co-located lidars and satellite measurements

description: As part of the Network for the Detection of Atmospheric Composition Change (NDACC), ground-based measurementsobtained from the JPL stratospheric ozone lidar and the NOAA stratospheric aerosol lidar at Mauna Loa, Hawaii over thepast two decades were used to investigate the impact of volcanic eruptions and pyro-cumulonimbus smoke plumes on thestratospheric aerosol load above Hawaii since 1999. Measurements at 355 nm and 532 nm conducted by these two lidarsrevealed Ångström exponents between -1.6 and -0.6 for background and smoke plumes, respectively. Measurements of theNabro plume by the JPL lidar in 2011/2012 showed a lidar ratio of (64.0+-12.7) sr at 355nm around the center of the plume.The new GloSSAC, CALIOP Level 3 and SAGE III-ISS stratospheric aerosol datasets were compared to the ground-basedlidar datasets. The intercomparison revealed a generally good agreement, with vertical profiles of extinction coefficient within 50% between 17 km and 23 km above sea level (ASL), and within 25% above 23 km ASL. The stratospheric aerosol depthderived from all these datasets shows good agreement, with the largest discrepancy (20%) being observed between the newCALIOP Level 3 and the other datasets. All datasets consistently reveal a relatively quiescent period between 1999 and 2005,followed by an active period of multiple eruptions (e.g., Nabro) until early 2012. Another quiescent period, with slightly higheraerosol background, lasted until mid-2017, when a combination of extensive wildfires and multiple volcanic eruptions caused a significant increase in stratospheric aerosol loading. This loading maximized at the very end of the time period considered(fall 2019) as a result of the Raikoke eruption, the plume of which ascended to 26 km altitude in less than three months.

title: Phase behavior of clathrate hydrates in the ternary H2O-NH3-Cyclopentane system

description: Titan, Saturn’s largest satellite, is the only icy moon with a dense atmosphere which is composed mainly of N2. Methane, the second most abundant constituent, would be depleted in only 30-100 Myr by active photochemistry, suggesting replenishment from Titan’s interior. Under Titan’s near-surface conditions, clathrate hydrates are the stable form of methane and ice together, making them a likely methane reservoir. Cassini-Huygens observations suggest that ammonia is the main source of Titan’s atmospheric N2. Ammonia is known to decrease the melting point of water ice and some clathrate hydrates such as those of tetrahydrofuran. The present study investigates the interaction of ammonia with cyclopentane clathrate hydrates (atmospheric analog for methane clathrates) via a detailed examination of phase behavior using micro-Raman spectroscopy, differential scanning calorimetry, and X-ray diffraction. The results show that ammonia has the same effect on the stability of the cyclopentane clathrate as on tetrahydrofuran clathrate and on ice by lowering the dissociation temperature by several tens of degrees and inducing incongruent melting. Ammonia does not interact directly with cyclopentane, and does not appear to be incorporated into cyclopentane clathrate structure, whether in the lattice or within the cages. A similar effect could be expected for methane clathrates. The presence of ammonia in Titan’s crust would thus destabilize methane clathrates, resulting in outgassing and the replenishment of atmospheric methane.

title: Computer Model Emulation with High-Dimensional Functional Output in Large-Scale Observing System Uncertainty Experiments

description: Observing system uncertainty experiments (OSUEs) have been recently proposed as a cost- eective way to perform probabilistic assessment of retrievals for NASA's Orbiting Carbon Observatory-2 (OCO-2) mission. One important component in the OCO-2 retrieval algo- rithm is a full-physics forward model that describes the mathematical relationship between atmospheric variables such as carbon dioxide and radiances measured by the remote sensing instrument. This complex forward model is computationally expensive but large-scale OSUEs require evaluation of this model numerous times, which makes it infeasible for comprehensive experiments. To tackle this issue, we develop a statistical emulator to facilitate large-scale OS- UEs in the OCO-2 mission with independent emulation. Within each distinct spectral band, the emulator represents radiances output at irregular wavelengths via a linear combination of basis functions and random coecients. These random coecients are then modeled with nearest-neighbor Gaussian processes with built-in input dimension reduction via active sub- space. The proposed emulator reduces dimensionality in both input space and output space, so that fast computation is achieved within a fully Bayesian inference framework. Validation experiments demonstrate that this emulator outperforms other competing statistical methods and a reduced order model that approximates the full-physics forward model. Supplementary materials for this article are available online.

title: Cropland Carbon Uptake Delayed and Reduced by 2019 Midwest Floods

description: While large-scale floods directly impact human lives and infrastructures, they also profoundly impact agricultural productivity. New satellite observations of vegetation activity and atmospheric CO2 offer the opportunity to quantify the effects of such extreme events on cropland carbon sequestration. Widespread flooding during spring and early summer 2019 delayed crop planting across the U.S. Midwest. As a result, satellite observations of solar-induced chlorophyll fluorescence (SIF) from the TROPOspheric Monitoring Instrument (TROPOMI) and the Orbiting Carbon Observatory (OCO-2) reveal a shift of 16~days in the seasonal cycle of photosynthetic activity relative to 2018, along with a 15% lower peak photosynthesis rate. We estimate the 2019 anomaly to have led to a reduction of -0.21 PgC in gross primary production (GPP) in June and July, partially compensated in August and September (+0.14 PgC). The growing season integral results in a 4% reduction in cropland GPP of the midwest, but a 3% increase for areas with cropland ratio less than 10%. Using an atmospheric transport model, we show that a decline of ~0.1 PgC in the net carbon uptake during June and July is consistent with observed CO2 enhancements of up to 10 ppm in the midday boundary layer from Atmospheric Carbon and Transport - America (ACT-America) aircraft and ~1 ppm in column-averaged dry-air mole fractions from OCO-2. This study quantifies the impact of floods on cropland productivity and demonstrates the potential of combining SIF with atmospheric CO2 observations to monitor regional carbon flux anomalies.

title: Improved infrared photometry and a preliminary parallax measurement for the extremely cold brown dwarf CWISEP J144606.62-231717.8

description: We present follow-upSpitzerobservations at 3.6μm (ch1) and 4.5μm (ch2) of CWISEP J144606.62–231717.8, one of the coldest known brown dwarfs in the solar neighborhood. This object was found by mining the Wide-field Infrared Survey Explorer (WISE) data via the CatWISE Preliminary Catalog by Meisner et al. (2019b), where an initial Spitzer color of ch1–ch2 = 3.71±0.44 mag was reported. Additional Spitzer data presented here allows us to revise its color to ch1–ch2 = 2.986±0.048 mag, which makes CWISEP J144606.62–231717.8 one of the reddest brown dwarfs ever observed. A preliminary trigonometric parallax measurement, based on a combination of WISE and Spitzer astrometry, places this object at a distance of 10.1+1.7−1.3pc.

title: Towards mapping the diversity of canopy structure from space with GEDI

description: Plant biodiversity supports life on Earth and provides a range of important ecosystem services, but is 11 under severe pressure by global change. Structural diversity plays a crucial role for carbon, water and energy 12 cycles and animal habitats. However, it is very difficult to map and monitor over large areas, limiting our ability 13 to assess the status of biodiversity and predict change. NASA’s Global Ecosystem Dynamics Investigation (GEDI) 14 provides a new opportunity to measure 3D plant canopy structure of the world’s temperate, Mediterranean and 15 tropical ecosystems, but its potential to map structural diversity is not yet tested. Here, we use wall-to-wall airborne 16 laser scanning (ALS) to simulate GEDI data (GEDIsim) over 7380 km2 in the southern Sierra Nevada mountains in 17 California, and evaluate how well GEDI’s sampling scheme captures patterns of structural diversity. We evaluate 18 functional richness and functional beta diversity in a biodiversity hot spot. GEDIsim performed well for trait 19 retrievals (r2 = 0.68) and functional richness mapping (r2 = 0.75) compared to ALS retrievals, despite lower 20 correlations in complex terrain with steep slopes. Functional richness patterns were strongly associated with soil 21 organic carbon stocks and density as well as variables related to water availability, and could be appropriately 22 mapped by GEDIsim with and without cloud cover. Functional beta diversity was more strongly related to local 23 changes in topography and more challenging to map, especially with decreasing sampling density. The reduced 24 number of GEDIsim shots when simulating cloud cover lead to a strong overestimation of beta diversity and a 25 reduction of r2 from 0.64 to 0.40 compared to ALS. The ability to map functional richness has been demonstrated 26 with potential application at continental scales that could be transformative for our understanding of large-scale 27 patterns of plant canopy structure, diversity and potential links to animal diversity, movement and habitats.

title: The Bose-Einstein Condensate and Cold Atom Laboratory

description: Microgravity eases several constraints limiting experiments with ultracold and condensed atoms on ground. It enables extended times of flight without suspension and eliminates the gravitational sag for trapped atoms. These advantages motivated numerous initiatives to adapt and operate experimental setups on microgravity platforms. We describe the design of the payload, motivations for design choices, and capabilities of the Bose-Einstein Condensate and Cold Atom Laboratory (BECCAL), a NASA-DLR collaboration. BECCAL builds on the heritage of previous devices operated in microgravity, features rubidium and potassium, multiple options for magnetic and optical trapping, different methods for coherent manipulation, and will offer new perspectives for experiments on quantum optics, atom optics, and atom interferometry in the unique microgravity environment on board the International Space Station.

title: A Passive Microwave Retrieval Algorithm with Minimal View Angle Bias: Application to the TEMPEST-D CubeSat Mission

description: The rapid development of miniaturized satellite instrument technology has created a new opportunity to deploy constellations of passive microwave (PMW) radiometers to permit retrievals of the same Earth scene with very high temporal resolution to monitor cloud evolution and processes. In order for such a concept to be feasible, it must be shown that it is possible to distinguish actual changes in the atmospheric state from the variability induced by making observations at different Earth incidence angles (EIAs). To this end, we present a flexible and physical optimal estimation-based algorithm designed to retrieve profiles of atmospheric water vapor, cloud liquid water path, and cloud ice water path from cross-track PMW sounders. The algorithm is able to explicitly account for the dependence of forward model errors on EIA and atmospheric regime. When the algorithm is applied to data from the Temporal Experiment for Storms and Tropical Systems Technology Demonstration (TEMPEST-D) CubeSat mission, its retrieved products are generally in agreement with those obtained from the similar but larger Microwave Humidity Sounder instrument. More importantly, when forward model brightness temperature offsets and assumed error covariances are allowed to change with EIA and sea surface temperature, view angle-related biases are greatly reduced. This finding is confirmed in two ways: through a comparison with reanalysis data and by making use of brief periods in early 2019 during which the TEMPEST-D spacecraft was rotated such that its scan pattern was along-track, allowing dozens of separate observations of any given atmospheric feature along the satellite’s ground track.

title: Cautionary analysis of spectral radiance from Io’s active volcanoes derived from Galileo Near Infrared Mapping Spectrometer (NIMS) data

description: Between 1996 and 2001, the Galileo Near Infrared Mapping Spectrometer (NIMS) obtained one hundred and ninety observations of the volcanic jovian moon Io. These are the best observations to date of thermal emission from Io’s diverse, powerful, and multitudinous volcanoes. Rathbun et al. (2018) [Astron. J., 156, 207] published a list of 287 measurements of 3.5 µm spectral radiance from some of Io’s volcanoes, derived from NIMS data. However, when compared with previous published estimates, these spectral radiances greatly underestimate thermal emission from Io’s most powerful volcanoes, including Loki Patera, Pele, Amirani and Pillan, all important contributors to Io’s heat flow. The underestimations are in large part due to the methodology used by Rathbun et al., which incorporated null values into the quantification of spectral radiance. Previously published analyses (in particular, Davies et al., 2012, GRL, 39, L01201) utilize unadulterated NIMS radiance products and techniques that yield accurate spectral radiances. These radiances compare well with contemporaneous ground-based observations obtained by the NASA Infrared Telescope Facility (IRTF). Spectral radiance null values in the 3- to 4.3-µm range used by Rathbun et al. were caused by detector saturation. Rathbun et al. further suggest that the number of hot spots in a given area is a suitable proxy for total heat flow. This hypothesis is tested and is found to be false.

title: Validating an automated nucleic acid extraction device for omics in space using whole cell microbial reference standards

description: NASA has made great strides in the last five years to develop a suite of instruments for the International Space Station in order to perform molecular biology in space. However, a key piece of equipment that has been lacking is an instrument that can extract nucleic acids from an array of complex human and environmental samples. The Omics in Space team has developed the µTitan (simulated micro(µ) gravity tested instrument for automated nucleic acid) system capable of automated, streamlined, nucleic acid extraction that is adapted for use under microgravity. The µTitan system was validated using a whole cell microbial reference (WCMR) standard comprised of nine bacteria titrated at concentrations that would challenge the performance of the instrument as well as resolve detection limits for isolating DNA. Quantitative assessment of system performance was measured by comparing instrument input challenge dose vs recovery by Qubit spectrofluorometry, RTqPCR, Bioanalyzer, and next generation sequencing. Overall, results indicate that the µTitan system performs equal to or greater than a similar commercially available, earth-based, automated nucleic acid extraction device. The µTitan system was also tested in Yellowstone National Park (YNP) with the WCMR, to mimic a remote setting, with limited resources. The performance of the device at YNP was comparable to that in a laboratory setting. Such a portable, field deployable, nucleic extraction system will be valuable for environmental microbiology as well as health care diagnostics in preventing microbial diseases.

title: Rotation of Two Micron All Sky Survey Clumps in Molecular Clouds

description: We have analyzed the rotational properties of 12 clumps using 13CO (1–0) and C18O (1–0) maps of the Five College Radio Astronomy Observatory 13.7 m radio telescope. The clumps, located within molecular clouds, have radii (R) in the range of 0.06 – 0.27 pc. The direction of clump elongation is not correlated with the direction of the velocity gradient. We measured the specific angular momentum (J/M) to be between 0.0031 and 0.036 pc kms−1 based on 13CO images, and between 0.0036 and 0.030 pc kms−1 based on C18O images. The consistency of J/M based on different tracers indicates the 13CO and C18O in dense clumps trace essentially the same material despite significantly different opacities. We also found that J/M increases monotonically as a function of R in power–law form, J/M / R1.75 ± 0.45. The ratio between rotation energy and gravitational energy, !, ranges from 0.0018 to 0.053. The small values of ! imply that rotation alone is not sufficient to support the clump against gravitational collapse.
