title: Supplement to: Comparison of Optimal Estimation HDO/H2O Retrievals from AIRS with ORACLES measurements

description: In this supplement we assess the sensitivity of HDO and H2O retrievals to the choice of forward model. All the retrievals in this paper were obtained from the MUSES retrieval framework using the Optimal Spectral Sampling (OSS) forward model (Moncet et al., 2008, 2015). The OSS method was designed specifically for the modeling of radiances measured by sounding radiometers in the infrared (Moncet et al., 2008, 2015), although it is applicable throughout the microwave, visible, and ultraviolet spectral regions. OSS uses an extension of the exponential sum fitting of transmittances technique in that channel-average radiative transfer is obtained from a weighted sum of monochromatic calculations. Among the advantages of the OSS method is that its numerical accuracy, with respect to a reference line-by-line model, is selectable, allowing the model to provide whatever balance of accuracy and computational speed is optimal for a particular application. Only a few monochromatic points are required to model channel radiances with a brightness temperature accuracy of 0.05 K. The version of OSS used here is trained with the monochromatic Atmospheric and Environmental Research, Inc. (AER) Line-By-Line Radiative Transfer Model (LBLRTM_v12.4) (Clough et al., 2005) using spectroscopic parameters from the ‘HIgh-resolution TRANsmission’ database (HITRAN12) (Rothman et al., 2013) plus line coupling coefficients for CO2 and CH4 calculated at AER.

title: Rapid collaborative knowledge building via Twitter after significant geohazard events

description: Twitter is an established social media platform valued by scholars as an open way to disseminate scientific information and to publicly discuss research results. Scientific discussions on Twitter are viewed by the media who can then pass on information to the wider public. Social media is used widely by geoscientists, but there is little documentation currently available regarding the benefits of this to the scientist and the public, or the limitations. Here, we take the example of two 2018 earthquake-related events which were widely commented on Twitter by geoscientists: the Palu Mw7.5 earthquake and tsunami in Indonesia and the long-duration Mayotte island seismo-volcanic crisis in the Indian Ocean. We build our study on a content and contextual analysis of selected Twitter threads about the geophysical characteristics of these events. From the analysis of these two examples, we show that Twitter promotes very rapid building of knowledge in the minutes to hours and days following an event via an efficient exchange of information and active discussion between the scientists themselves and with the public. We discuss the advantages and potential pitfalls of this relatively novel way to make scientific information accessible to scholarly peers and to lay people. We argue that scientific discussion on Twitter breaks down the traditional “ivory towers” of academia, participates to the growing trends towards open science, and may help people to understand how science is developed, and, in the case of natural/environmental hazards, to better understand their risks

title: Updated Geopotential Shapes of Jupiter and Saturn using Juno and Cassini Grand Finale Gravity Science Measurements

description: A commonly used shape model for the giant plants of Jupiter and Saturn is an oblate ellipsoid, a simplified model of the equipotential shape. The ellipsoidal shape models were originally derived from radio occultation data and gravity data after the Voyager flybys in 1979. Through precise Doppler tracking of NASA’s Juno and Cassini spacecraft telecommunications links, zonal coefficients in a spherical harmonic expansion of the gravity field of Jupiter and Saturn have been resolved to degree 10, including the detection of non-zero odd zonal harmonics, which have been interpreted as differential rotation in the atmosphere for both planets. In this work, we construct the equipotential surfaces of Jupiter and Saturn using the recently measured gravity fields determined by Juno through perijove 8, and Cassini through end of mission. For both planets, even zonal harmonics dominate the equipotential shape, differing from the reference ellipsoid up to ~32 km at Jupiter and ~125 km at Saturn in the mid-latitude regions. Saturn’s internal rotation period estimated with ring seismology produces a shape that is fully consistent with the Pioneer and Voyager radio occultation measurements; and Jupiter’s shape is fully consistent with the Pioneer and Voyager radio occultation measurements. With current equipotential theory, the recent analysis of the depth of the deep zonal flow on Jupiter and Saturn cannot fully be explained by the shape from current radio occultation measurements; additional occultation measurements and reanalysis of the Pioneer and Voyager radio occultations and will be useful for further constraining the shape of the planets.

title: An Aircraft Wetland Inundation Experiment Using GNSS Reflectometry

description: In early May of 2017, a flight campaign was conducted over Caddo Lake, Texas, to test the ability of Global Navigation Satellite System-Reflectometry (GNSS-R) to detect water underlying vegetation canopies. This paper presents data from that campaign and compares them to Sentinel-1 data collected during the same week. The low-altitude measurement allows for a more detailed assessment of the forward-scattering GNSS-R technique, and at a much higher spatial resolution, than is possible using currently available space-based GNSS-R data. Assumptions about the scattering model are verified, as is the assumption that the surface spot size is approximately the Fresnel zone. The results of this experiment indicate GNSS signals reflected from inundated short, thick vegetation, such as the giant Salvinia observed here, results in only a 2.15 dB loss compared to an open water reflection. GNSS reflections o inundated cypress forests show a 9.4 dB loss, but still 4.25 dB above that observed over dry regions. Sentinel-1 data show a 6-dB loss over the inundated giant Salvinia, relative to open water, and are insensitive to standing water beneath the cypress forests, as there is no dierence between the signal over inundated cypress forests and that over dry land. These results indicate that, at aircraft altitudes, forward-scattered GNSS signals are able to map inundated regions even in the presence of dense overlying vegetation, whether that vegetation consists of short plants or tall trees.

title: Manganese oxides in Martian meteorites Northwest Africa (NWA) 7034 and 7533

description: We report the discovery of indigenous Mn-oxides in Martian regolith breccias Northwest17 Africa (NWA) 7034 and 7533. These Mn-oxides occur in Mn-rich regions as nanocrystals mixed18 with silicates, FeOOH, and possible phosphates. The Mn-rich regions contain up to 34 wt% Mn19 and typically display large chemical gradients on the scale of 10–20 μm. The Martian origin of20 Mn-oxides was established by the presence of Mn-rich glass (4.8–5.6 wt% Mn) in the fusion crust21 that crosscuts a Mn-oxides-bearing monzonite clast and by the absence of Mn-oxides on the22 environmentally exposed surfaces (exterior and fractures) of the meteorites. Manganese K-edge23 X-ray absorption spectrum (XAS) of the Mn-rich glass in the fusion crust indicated that this glass24 included high-valent Mn species. Synchrotron micro-X-ray diffraction of a Mn-rich region in a25 basalt clast and XAS of Mn-rich regions in three monzonite clasts indicate Mn-oxides in these26 regions are dominantly hollandite-structured with 67–85 mol% of the total Mn being Mn4+. The27 fact that Mn-rich regions are present in diverse petrological associations but are absent in the28 matrix of the breccias indicates that the Mn-oxides formed through surface alteration prior to the29 final brecciation event that assembled NWA 7034 and 7533. Thus, the age of the Mn-oxides isolder than the lithification age (arguably 1.35 Ga) 30 of NWA 7034 and 7533. Together with findings31 of Mn-rich phases within Noachian and Hesperian sedimentary strata in Endeavor and Gale craters,32 our results suggest that Mn-oxides are a common weathering product on Mars surface, suggesting33 aqueous environment on the Martian surface with high redox potential.

title: Constraining symmetron dark energy using atom interferometry

description: The symmetron field is one of the promising candidates of dark energy scalar fields. In all viable candidate field theories, a screening mechanism is implemented to be consistent with existing tests of general relativity. The screening effect in the symmetron theory manifests its influence only to the thin outer layer of a bulk object, where inside a dense material the symmetry of the field is restored and no force exists. For pointlike particles such as atoms, the depth of screening is larger than the size of the particle, such that the screening mechanism is ineffective and the symmetron force is fully expressed on the atomic test particles. Extra force measurements using atom interferometry are thus much more sensitive than bulk mass based measurements, and indeed have placed the most stringent constraints on the parameters characterizing symmetron field in certain region. There is however no clear direct connection between the laboratory measurements and astrophysical observations, where the constraints are far separated by 10 orders of magnitude in the parameter space. In this paper, we present a closed-form expression for the symmetron acceleration of realistic atomic experiments. The expression is validated through numerical simulations for a terrestrial fifth-force experiment using atom interferometry. As a result, we show the connection of the atomic measurement constraints to the astrophysical ones. We also estimate the attainable symmetron constraints from a previously proposed experiment in space intended for a test of chameleon theory. The atomic constraints on the symmetron theory will be further improved by orders of magnitude

title: Exposure to Cold Temperature Affects the Spring Phenology of Alaskan Deciduous Vegetation Types

description: Temperature is a dominant factor driving arctic and boreal ecosystem phenology, including leaf budburst and gross primary production (GPP) onset in Alaskan spring. Previous studies hypothesized that both accumulated growing degree day (GDD) and cold temperature (chilling) exposure are important to leaf budburst. We test this hypothesis by combining both satellite and aircraft vegetation measurements with the Community Land Model Version 4.5 (CLM), in which the end of plant dormancy depends on thermal conditions (i.e., GDD). We study the sensitivity of GPP onset of different Alaskan deciduous vegetation types to a GDD model with chilling requirement (GC model) included. The default CLM simulations have earlier day of year of GPP onset (1–12 days) over Alaska vegetated regions compared to satellite constrained estimates from the Polar Vegetation Photosynthesis and Respiration Model. Integrating a GC model into CLM shifts the phase and amplitude of GPP. During 2007–2016, mean GPP onset is postponed by 5±7, 4±8, and 1±6 days over Alaskan northern tundra, shrub, and forest, respectively. The GC model has the greatest impact during warm springs, which is critical for predicting phenology response to future warming. Overall, spring GPP high bias is reduced by 10%. Thus, including chilling requirement in thermal forcing models improves northern high-latitude phenology, but leads to other impacts during the growing season which require further investigation.

title: An Extremely Large Ka-Band Reflectarray Antenna for Interferometric SAR

description: The Surface Water Ocean Topography (SWOT) mission, currently in development at NASA’s Jet Propulsion Laboratory, will employ the Ka-band Radar Interferometer (KaRIn) instrument to characterize ocean height at the unprecedented spatial resolution of 2 km, and is designed to provide a global inventory of significant terrestrial water bodies (area &gt;(250m)2) and rivers (width &gt;50-100m). The key enabling technology for this instrument is a pair of large deployable antennas that form the interferometer. This paper describes the development of the largest reflectarray antenna yet developed for a space flight application, a 5m x 0.26m offset-fed reflectarray antenna with a 4.37m focal length. The paper provides details on critical aspects of the development, including RF design and analysis, fabrication, and measurement. We discuss unique requirements imposed by the interferometer which resulted in significant design and verification challenges. Flight hardware measurements demonstrated a gain of approximately 49.5dB, corresponding to an efficiency of 52%, and an azimuth beamwidth of 0.105 degrees with beam pointing knowledge of 5 millidegrees. Accurate characterization of these antenna performance parameters is critical to the success of the KaRIn instrument.

title: Global thermodynamic, transport-property and dynamic characteristics of the Venus lower atmosphere below the cloud layer

description: This study investigates the global characteristics of the Venus lower atmospherebelow the cloud layer. Starting from available data regarding species composition,temperature and pressure, the general thermodynamic and transport properties ofthe Venus lower atmosphere are first computed at altitudes below the cloud layer.The thermodynamic and transport properties are validated with known data. Athermodynamic stability analysis for a variety of potentially existing mixtures isconducted to highlight the sensitivity of the thermodynamic regime to the variationof the species molar fractions. The limits of thermodynamic stability are representedin the thermodynamic phase diagram of the mixture, and thus regions ofphase stability and instability are determined. It is found that the Venus loweratmospherethermodynamic regime is located in the stable, single-phase regime,with supercritical conditions occurring in the lower few kilometers, thereby validatingad-hoc expectations which have never envisaged the existence of a two-phaseregime at those altitudes. Using thermodynamic and transport-property informationthus computed, several non-dimensional numbers are calculated. The Prandtlnumber is first evaluated. Then, the characteristic Reynolds number is estimatedfor different assumed length scales, showing that, independent of the length scale,the entire lower atmosphere below the cloud deck is in a fully-turbulent flow regime.Finally, the speed of sound and the Mach number are computed as function of altitude.The information obtained from all these calculations fills a scientific void,and may be crucial for the design of landers on the Venus surface.

title: Improved Signals for Differential One-way Range

description: This paper describes the current limiting error source for Delta Differential One-way Range (∆DOR), provides a means to reduce this error, and lists the benefits to deep space navigation. Particular advantages for Small Satellite class missions are addressed. The key idea is spreading the spacecraft DOR signal with a pseudonoise (PN) code to make the spacecraft signal spectrum closely resemble the spectrum of natural radio sources used for instrument calibration. How spectral differences affect the measurement are discussed. The paper describes the general formulation for PN DOR signal design, and the specific X-band implementation of PN DOR on a software defined radio at JPL. Finally, a prototype implementation at Ka-band, providing even better performance, is presented.
