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... |

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... |

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... |

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... |

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, "Burst properties of the highly active FRB 20201124A using uGMRT", https://doi.org/10.48577/jpl.0QQQO2, Monthly Notices of the Royal Astronomical Society, JPL Open Repository
We report the observations and the detection of 48 bursts from FRB 20201124A with the upgraded Giant Metrewave Radio Telescope at 550-750 MHz. These observations simultaneously led to the localization of FRB 20201124A to a SDSS galaxy and led to the first detection of persistent... |
