Preliminary Results of Marine Gravity Anomaly and Bathymetry from SWOT Wide-Swath altimeter data
<p><span>We explore the potential of Ka-band radar interferometry (KaRIn) data from the SWOT mission for marine gravity and bathymetry applications. Our evaluation includes determining the deflection of vertical (DOV) using the least squares collocation (LSC) method, recovering gravity anomalies with the inverse Vening-Meinesz (IVM) approach, and predicting bathymetry through the gravity-geological method (GGM). SWOT-derived gravity anomalies in the study area, located between 20ºN - 30ºN and 135ºE - 145ºE, lies at the convergence of the Pacific and Eurasian tectonic plates. KaRIn data (only seven months) recovered gravity anomalies with an accuracy of 2.37 mGal, which is better than current models.</span></p> <p><span>The details of the method are discussed in a manuscript submitted to GRL.</span></p> <p> </p>
Large-eddy simulation of an atmospheric bore and associated gravity wave effects on wind farm performance in the Southern Great Plains
<p>Animations from weather radars (observations) and simulations (modeling) of an atmospheric bore and associated gravity waves during the AWAKEN field campaign from a case study on 06 June 2023. The first animation is reflectivity from the NEXRAD WSR-88D system at the Oklahoma City radar site (KTLX) operated by the National Weather Service. The second animation is wind speed at 95, 145, and 270 m agl from the Texas Tech X-Band radars at the AWAKEN site. The third and fourth animations are for simulation results using the Weather Research and Forecasting model (WRF) with two domains. The third animation is vertical velocity at 1 km agl and potential temperature at 200 m agl on domain d01, which has a horizontal grid spacing of 300 m. The fourth animation is hub-height wind speed and perturbation pressure along with simulated power output for 3 wind turbines in each of the four rows on domain d01, which has a horizontal grid spacing of 20 m. The wind turbines are NREL 2.8 MW turbines parameterized using a generalized actuator disk. </p> <p>These animations are included as supplementary material for the manuscript "Large-eddy simulation of an atmospheric bore and associated gravity wave effects on wind farm performance in the Southern Great Plains" submitted to <em>Wind Energy Science</em>. </p>

Gas permeability and mechanical properties of dust grains at hyper- and zero-gravity
<p>Two-phase flow experimental data obtained from the TEMPusVoLA facility over the course of three Zero-gravity parabolic flight campaigns (<strong>PFCs</strong>). The experiment, designated 'System 1' , contains low-pressure gas and analogue dust particles (of diverse compositions, shapes, and sizes) that experience a low-pressure gas cross-wind normal to the gravitational force vector. During steady flight, the particles pack into the lower end of the chamber and the layer of granular media creates a pressure differential, which is used to extract permeability coefficients in both the continuum and molecular-diffusion dominated regimes. We compare the permeability both with and without the effect of gravity and make comparisons with the conditions on low-gravity objects in the solar system, such as planetesimals and the dust particles that comprise them. In particular, we are able to compare and contrast the cohesiveness of the dust-regolith analogue types, which has consequences for formation theories of Solar-system bodies. </p> <p> </p> <p><strong>Data products: </strong></p> <p><strong>Pressure, acceleration</strong></p> <p>Each file corresponds to a particular parabolic flight campaign and day of flight. The 4th Swiss PFC lasted 1 day in 2020. The 75 ESA PFC lasted 3 days in 2021, and the the 78th ESA PFC lasted 3 days in 2022. Data was obtained in System 1 during all flights of all campaigns, and for a set of 12-16 parabolas. On each parabola, we studied the sample in one out of three chambers and changed the gas mass flux rate after cycling through all three samples. The below files were used to correlate changes in sample gas permeability with changes in gravitational loading. </p> <p>-- Raw pressure files output from 6-channel pressure logger measuring pressure as function of time as .csv files: DATALOG_DATE. </p> <p>-- Raw acceleration files output from accelerometer measuring gravitational load on aircraft.</p> <p><strong>Imaging data</strong></p> <p>-- Movie sequences obained with high-resolution thor-labs camera. All three chambers were imaged, despite only one chamber being subject to active gas flow at any given time. movie1 and movie 2 are referenced in the associated publication. </p> <p><strong>Multimeter data</strong></p> <p><strong>-- </strong>Output from photo-diodes measured across 9 channels using a Keithley Multimeter/Multiplexor. Acquisition speed was 27 Hz. </p>
Position sense in altered gravity
<p>These data originate from a parabolic flight experiment in which the influence of altered gravity (hypergravity, microgravity) on the human sense of position was investigated using three classical methods (two-arm matching, two-arm pointing, one-arm repositioning).</p>
