Athina Peidou, 2021, "Spatiotemporal characterization of geophysical signal detection capabilities of GRACE-FO", https://doi.org/10.48577/jpl.AZ1CPD, Geophysical Research Letters, JPL Open Repository
The intersatellite range measurements between the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) satellite pair enable mapping time variations in Earth’s gravity field. The Laser Ranging Interferometer (LRI) and Microwave Instrument (MWI) provide independent range m... |

Pardo, Kristofer M, 2021, "Detecting dark matter subhalos with the Nancy Grace Roman Space Telescope", https://doi.org/10.48577/jpl.YGOKUC, Physical Review D, JPL Open Repository
Dark matter substructure is a promising way of distinguishing between dark matter models. While cold dark matter predicts halos down to quite small scales, other models typically predict a cut-off in the subhalo mass function. If these subhalos existed in the Milky Way, they woul... |

Juilin Li, 2021, "The Potential Influence of Falling Ice Radiative Effects on Central Pacific El Niño Variability under Progressive Global Warming", https://doi.org/10.48577/jpl.AQHBMO, Environmental research letter, JPL Open Repository
AbstractThis study examines the potential influence of inserting falling ice (snow) radiative effects (FIREs) in GCMs on simulated surface wind stress and sea surface temperature (SST) in the evolution of Central Pacific El Niño (CP-El Niño) events under a progressive warming cli... |

Cathleen Jones, 2021, "Using Rapid Repeat SAR Interferometry to improve Hydrodynamic Models of flood propagation in Coastal Wetlands", https://doi.org/10.48577/jpl.IRP4SA, Water Resources Research, JPL Open Repository
The propagation of tides and riverine floodwater in coastal wetlands is controlled by subtle topographic differences and a thick vegetation canopy. High-resolution numerical models have been used in recent years to simulate fluxes across wetlands. However, these models are based... |

Waliser, Duane E, 2021, "Advances in the application and utility of subseasonal-to-seasonal predictions", https://doi.org/10.48577/jpl.EWYNXU, Bulletin of American Meteorological Society, JPL Open Repository
The subseasonal-to-seasonal (S2S) predictive timescale, encompassing lead times ranging from 2 weeks to a season, is at the frontier of forecasting science. Forecasts on this timescale provide opportunities for enhanced application-focused capabilities to complement existing weat... |

Rebecca Gustine, 2021, "Using ECOSTRESS to Observe Diurnal Variability in Water Temperature Conditions in the San Francisco Estuary", https://doi.org/10.48577/jpl.VFPDDC, Transactions on Geoscience and Remote Sensing, JPL Open Repository
Abstract—The San Francisco Estuary and Sacramento-SanJoaquin River Delta (Bay Delta) is a highly sensitive and criticalhabitat for the Delta Smelt, an endangered endemic fish, withwater temperature being a key determinant of habitat suitability.This study investigates the relatio... |

Miller, Charles E, 2021, "Sensitivity of Multi-frequency Polarimetric SAR Data to Post-Fire Permafrost Changes and Recovery Processes in Arctic Tundra", https://doi.org/10.48577/jpl.6FM72N, IEEE transactions on geoscience and remote sensing, JPL Open Repository
Abstract— We used full polarimetric L-band and P-band synthetic aperture radar (SAR) data collected from the recent NASA Arctic Boreal Vulnerability Experiment (ABoVE) airborne campaign and Sentinel-1 C-band dual-polarization data to understand the sensitivity of radar backscatte... |

Jonathan Jiang, 2021, "Assessing Planetary Complexity and Potential Agnostic Biosignatures using Epsilon Machines", https://doi.org/10.48577/jpl.XMNTOI, Nature Astronomy, JPL Open Repository
We present a new approach to exoplanet characterization using tech-niques from complexity science, with potential applications to biosig-nature detection. This agnostic method makes use of the temporalvariability of light reected or emitted from a planet. We use a tech-nique know... |

Elder, Clayton D, 2021, "Characterizing methane emission hotspots from thawing permafrost", https://doi.org/10.48577/jpl.ECH7DM, AGU Advances, JPL Open Repository
Methane (CH4) emissions from climate-sensitive ecosystems within the northern permafrost region represent a potentially large but highly uncertain source, with current estimates spanning a factor of seven (11 – 75 Tg CH4 yr-1). Accelerating permafrost thaw threatens significant i... |

Robert Wharton, 2021, "Scintillation timescale measurement of the highly active FRB 20201124A", https://doi.org/10.48577/jpl.YMKJ2N, Monthly Notices of the Royal Astronomical Society, JPL Open Repository
Scintillation of compact radio sources is caused by the interference between images caused by multipath propagation, and can be used to probe the intervening scattering plasma, and the velocities of the emitting source and scattering screen. In FRB20201124A, a repeating FRB which... |
