title: The Effectiveness of Agricultural Carbon Dioxide Removal using the University of Victoria Earth System Climate Model

description: This dataset comprises output from simulations used in "The Effectiveness of Agricultural Carbon Dioxide Removal using the University of Victoria Earth System Climate Model" by Rebecca C Evans and H Damon Matthews, published in Biogeosciences (2025). The data was collected to improve our understanding of how the climate responds to carbon removal when the sequestered carbon is stored temporarily in pools that can continue to interact with the atmosphere (nature-based removal). Included are time series from 12 future climate simulations: - 3 simulations that represent the climate's response to future emissions under the SSP 1-1.9, 2-4.5, and 5-8.5 emissions scenarios. - 3 simulations that have the same SSP scenarios (1-1.9, 2-4.5, 5-8.5) with the addition of a small amount of prescribed carbon dioxide removal in agricultural areas - 3 simulations that have the same SSP scenarios (1-1.9, 2-4.5, 5-8.5) but with moderate rates of agricultural CDR - 3 simulations that have the same SSP scenarios (1-1.9, 2-4.5, 5-8.5) but with high rates of agricultural CDR. The data provided here is the output of these simulations, and can be found in a netcdf format. The data is annual globally-averaged output of temperature, atmospheric CO2, carbon pools, etc. for the 100 years from the year 2000 to 2100. Brief description of the methodology: (1) Take projections for future CO2 under specific SSP scenarios from https://tntcat.iiasa.ac.at/SspDb (2) Modify the code of the UVic ESCM (https://terra.seos.uvic.ca/model/2.10/) to include a prescribed atmosphere-to-soil CO2 flux in agricultural areas (3) Prescribe this CO2 flux to linearly ramp from 0 in the present day, to a maximum value in 2050 based literature estimates of CDR that will be possible by 2050 for low, moderate, and high costs (4) Hold the CO2 flux constant after 2050 (5) Compare the results to the simulations with no prescribed CDR, to elucidate the impact of CDR on the climate A more detailed description of the methodology can be found in the published paper.

title: Fe-phosphates in Jezero Crater as evidence for an ancient habitable environment on Mars

description: Phosphorus is an essential component for life, and in-situ identification ofphosphate minerals that formed in aqueous conditions directly contributestoward one of themain goals of theMars 2020 Perseverance rover: to seeksigns of ancient habitable environments. In Jezero crater, proximity scienceanalyses within a conglomerate outcrop, “Onahu” demonstrate the presenceof rare Fe3+-bearing phosphate minerals (likely metavivianite, ferrolaueite,(ferro)beraunite, and/or santabarbaraite) embedded in a carbonate-richmatrix.While Fe-phosphates have been inferred previously onMars, this workpresents the most definitive in-situ identification of martian Fe-phosphateminerals to date, using textural, chemical, spectral, and diffraction analyses ofdiscrete green-blue grains. The Fe-phosphate minerals’ textural context alongwith comparisons to Earth analogs suggest they likely formed after oxidationof Fe2+-phosphate vivianite, the most common Fe-phosphate in sedimentaryenvironments on Earth, often associated with microbial activity and organics.While there is no obvious evidence of biological inputs in Onahu, if the Fephosphates’formation environment was similar to vivianite-rich sedimentaryenvironments on Earth, these minerals likely originally precipitated in conditionsfavorable to potential martian life — in a low temperature, reducingaqueous medium with high concentrations of bio-limiting elements, and Feredoxgradients that could provide an energy source. If the sample collectedfromOnahu (Otis_Peak) is returned to Earth, analysis of the Fe-phosphatesmayprovide new insights into ancient habitable environments on Mars.

title: S-Band Reflectarray Antenna for Venus Synthetic Aperture Radar and Radiometer

description: The European Space Agency’s EnVision mission to Venus will carry the NASA VenSAR radar instrument to produce near global high-resolution maps, topography, and brightness temperature measurements of the planet. The key enabling technology for this instrument is a large deployable antenna designed to meet the mission’s radar and radiometer requirements. This paper describes the design and initial development of one of the largest reflectarray antennas yet developed for a space flight application, a 6m x 0.7m offset-fed reflectarray antenna with a 2.75m focal length. The paper provides details on critical aspects of the design, including key RF and mechanical characteristics along with antenna system performance estimates.

title: Deployable MetaLens for G-Band Earth Science Applications

description: This paper describes a new deployable MetaLens concept for use in future spaceborne Earth Science radar to study the Earth’s Planetary Boundary Layer (PBL). The key to this design is a multilayer artificial dielectric Gradient Index (GRIN) lens which is realized as a stackup of tensioned polyimide layers, each of which supports a photoetched pattern of circular disks. A new lens design synthesis algorithm has been developed to handle the computational challenge of this design process. Initial test results for a 20 cm diameter Ka-band demonstration lens show very good performance. A G-Band breadboard lens indicates that the design is practical to build at 175 GHz.

title: Mapping Vegetation Structure from UAVSAR Tomography Using 3-D Convolutional Neural Networks

description: The NASA/JPL Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) instrument has performed tomographic SAR experiments over a number of study areas, including Rabi Forest in Gabon in 2016 and Sierra National Forest in California, USA in 2021. Tomographic SAR, or TomoSAR, is a technique enabling 3-D radar imaging with diverse applications including mapping of vegetation structure. Convolutional neural networks (CNNs) have shown widespread potential for many image processing and computer vision tasks such as image segmentation, classification, and object recognition. By using 3-D CNNs rather than 2-D CNNs, the filters can be applied to all three dimensions of a forest volume imaged by TomoSAR. We have trained 3-D CNN-based deep learning models to estimate canopy height and canopy cover from fully polarimetric UAVSAR TomoSAR images using lidar data as training and validation. When applied to canopy height estimation in the Rabi Forest study area, a trained network had root mean square error (RMSE) of 2.41 m (7\%) for test data held out from training. For canopy cover estimation in the Sierra National Forest study area, a trained network yielded RMSE of 10\% for test data held out from training. Further work can be done to optimize the network architecture, improve the output spatial resolution, and to check if these methods can be applied to other study areas or to other vegetation structure parameters such as above-ground biomass. The results show the strong potential of 3-D CNNs for mapping wall-to-wall vegetation structure from tomographic SAR imagery using lidar training data.

title: Direct Bandwidth Measurements of Dynamic Pressure Sensors

description: We present an experimental method for performing direct, high-speed dynamic pressure measurements of MEMS based sensors with bandwidths exceeding 1 MHz. We employ a focused nanosecond pulsed laser beam to produce a laser-induced spark that rapidly expands into a supersonic shock wave that stimulates the pressure transducer. A windowed chamber with an integrated heating element allows the sensor’s dynamic pressure response to be characterized at temperatures ranging from 25°C to 1000°C. A precision PID pressure control system is used to establish specific static pressure setpoints ranging from 1 Pa to 33,000Pa (absolute) that are dynamically modulated by the laser-induced shock wave. This method has significant repeatability, accuracy, and bandwidth advantages over other direct and indirect measurement methods such as employing a shock tube, ultrasonic excitation, or using a low frequency reciprocal calibration.

title: Hydrogen cyanide and hydrocarbons mix on Titan

description: This work reveals a striking exception to the well-established rule in chemistry that polar and nonpolar compounds do not spontaneously mix: insertion of methane, ethane, and other small hydrocarbons into the crystal lattice of hydrogen cyanide (HCN), a highly polar molecule. By mixing these components at cryogenic temperatures, we can observe distinct shifts in vibrational modes using Raman spectroscopy. Our computational predictions confirm that cocrystal structures of HCN and ethane, which match our experimental vibrational shifts closely, are thermodynamically and kinetically stable. Given that methane, ethane, and HCN are major components of the atmosphere and surface of Saturn’s moon Titan—where they play key roles in shaping chemistry, weather, and landscape—our findings may prove instrumental for explaining Titan’s chemical and geological evolution.

title: Identifying Wet Troposphere Delay in L-band InSAR Using Weather 2 Radar Reflectivity

description: Synthetic Aperture Radar (SAR) pulses undergo variable delays in the atmosphere due to pressure, temperature, and humidity changes in the troposphere, posing a major source of error in InSAR measurements. Wet troposphere delay, caused by condensed water and water vapor clouds, is particularly difficult to predict, yet can cause delays of tens of centimeters, significantly impacting surface displacement estimates. Our study employs a feature-comparison method using NOAA NEXRAD weather radar station reflectivity data to identify artifacts from wet tropospheric delays in InSAR phase change measurements derived from rapid repeat imaging data collected with the UAVSAR L-band SAR. NEXRAD's 5-minute scanning interval, compared to UAVSAR's 30-minute revisit time, enabled detection of phase artifacts caused by fast-moving and developing clouds. We identify regions in InSAR interferograms with tropospheric-induced phase artifacts by matching features common to InSAR phase outlier masks and NEXRAD high reflectivity masks. Matched results between NEXRAD reflectivity and InSAR phase noise show phase delays of up to 25 radians in L-band, corresponding to 48 cm of delay. Comparison with tropospheric delays calculated using the Generic Atmospheric Correction Online Service for InSAR (GACOS) showed that the weather model has insufficient spatial and temporal resolution to accurately estimate the observed wet troposphere delays. While our study focused on UAVSAR, the findings are applicable to other SAR missions, including the L-band NISAR mission, aiding identification and interpretation of InSAR results affected by tropospheric delays.

title: Satellite-based Analysis of CO2 Emissions in Global Cities: Regional, Economic, and Demographic Attributes

description: Cities play a crucial role in reducing global greenhouse gas emissions. While activity-based 26 (“bottom up”) emission estimates are widely used for global cities, they often lack independent 27 verification. In this study, we use remotely-sensed CO2 observations from the Orbiting Carbon 28 Observatory-3 (OCO-3) to “top-down” estimate CO2 emissions for 54 global cities. This global29 scale analysis is enabled by a computationally efficient, low latency Cross-Sectional Flux (CSF) 30 approach, which constrains urban plume shape using NO2 observations from TROPOMI and 31 trajectory simulations from HYSPLIT. Our satellite-based emission estimates for 54 global cities 32 agrees within 7% to two widely used bottom-up datasets but reveal regional discrepancies. 33 Bottom-up estimates tend to overestimate emissions for cities in Central East Asia and South and 34 West Asia, while underestimating emissions in Africa, East and Southeast Asia & Oceania, 35 Europe, and North America. Additionally, our satellite-based socioeconomic analysis shows that 36 1) high-income cities tend to have less carbon-intensive economies: North American cities emit 37 0.1 kg CO2 per USD of economic output, while African cities emit 0.5 kg CO2 per USD, and 2) 38 per capita emissions decrease with increasing population size, from 7.7 tCO2/person for cities manuscript submitted to AGU Advances 39 under 5 million residents to 1.8 tCO2/person for cities over 20 million residents. This study 40 highlights the potential of satellite data to bridge gaps between top-down and bottom-up 41 emission estimates, enhancing the robustness and transparency of emissions monitoring. Our 42 findings emphasize the growing role of satellite data in verifying urban CO2 emissions and 43 supporting efforts to mitigate emissions for global cities.

title: Advances in Infrared Remote Sensing

description: In this presentation, we will report our recent efforts in achieving high performance in Antimonides type-II superlattice (T2SL) based infrared photodetectors using the barrier infrared detector (BIRD) architecture. The high operating temperature (HOT) BIRD focal plane arrays (FPAs) offer the same high performance, uniformity, operability, manufacturability, and affordability advantages as InSb. However, mid-wavelength infrared (MWIR) HOT-BIRD FPAs can operate at significantly higher temperatures (&gt;150K) than InSb FPAs (typically 80K). Moreover, while InSb has a fixed cutoff wavelength (~5.4 µm), the HOT-BIRD offers a continuous adjustable cutoff wavelength, ranging from ~4 µm to &gt;15 µm, and is therefore also suitable for long wavelength infrared (LWIR) as well. The LWIR detectors based on the BIRD architecture has also demonstrated significant operating temperature advantages over those based on traditional p-n junction designs. HyTI (Hyperspectral Thermal Imager) and c-FIRST (compact Fire Infrared Radiance Spectral Tracker) based on JPL’s T2SL BIRD FPAs. Based on III-V compound semiconductors, the BIRD FPAs offer a breakthrough solution for the realization of low cost (high yield), high-performance FPAs with excellent uniformity and pixel-to-pixel operability.
