Bin Guan, 2024, "A Regionally Refined Quarter-degree Global Atmospheric Rivers Database Based on ERA5, 1940–2022", https://doi.org/10.48577/jpl.VRTI0A, Scientific Data, JPL Open Repository
Atmospheric rivers (ARs) are narrow, elongated, synoptic jets of water vapor that play important roles in the global water cycle. The continually developing Tracking Atmospheric Rivers Globally as Elongated Targets(tARget) algorithm identifies AR objects at individual time steps... |

Eugene Serabyn, 2024, "A geometric-phase-based phase-knife mask for stellar nulling", https://doi.org/10.48577/jpl.ST5DXO, Optics Express, JPL Open Repository
Exoplanets can potentially be detected very close to stars with single-mode cross-aperture nulling interferometry, a photonic nulling technique that relies on the inability of an anti-symmetric stellar point-spread function to couple to a single-mode fiber’s symmetric mode. We pr... |

Kyle Uckert, 2024, "Characterizing Hydration Carrier Phases in Altered Rocks of Jezero Crater Fan and Floor Geologic Units with SHERLOC on Mars 2020", https://doi.org/10.48577/jpl.VXO2EV, Journal of Geophysical Research: Planets, JPL Open Repository
The Mars 2020 Perseverance rover has explored fluvio-lacustrine sedimentary rocks within Jezero crater. Prior work showed that igneous crater floor Séítah and Máaz formations have mafic mineralogy with alteration phases that indicate multiple episodes of aqueous alteration. In th... |

Parazoo, Nicholas; Byrne, Brendan, 2024, "Science Data for the article “More Frequent Spaceborne Sampling of XCO2 Improves Detectability of Carbon Cycle Seasonal Transitions in Arctic-Boreal Ecosystems", https://doi.org/10.48577/jpl.OASBRL, JPL Open Repository
These datasets are results from modeling experiments to test for the impact of spaceborne sampling of atmospheric CO2 on estimates of land-atmospheric CO2 exchange in the Arctic region. Specifically, we use flux inversion observing system sensitivity experiments (OSSE) to test th... |

Olga Verkhoglyadova, 2024, "Temporal Variability of Equatorial Ionization Anomaly Crest Locations Extracted from Global Ionospheric Maps", https://doi.org/10.48577/jpl.VWPE33, Space Weather, JPL Open Repository
The Equatorial Ionization Anomaly (EIA) crest location is known to vary over a variety of temporal scales. For the first time we perform a statistical survey of the temporal variation of the EIA crest location viewed globally and spanning 20 years. We extract the crest location f... |

Joana Voigt, 2024, "Unraveling Geologic Processes and Aqueous Alteration at Tyrrhena Terra, Mars", https://doi.org/10.48577/jpl.OXSPKN, JGR: Planets, JPL Open Repository
The central eastern Tyrrhena Terra region of Mars contains abundant aqueously altered minerals including Fe/Mg-smectites, smectite/chlorite mixtures, chlorites, zeolites, and carbonates. This study relates detections of these alteration-generated materials with mafic outcrops, ge... |
