Arnaud Cerbelaud, 2024, "Peak Flow Event Durations in the Mississippi River Basin, and Implications for Temporal Sampling Requirements to Capture River Dynamics", https://doi.org/10.48577/jpl.KZQVM7, Geophysical Research Letters, JPL Open Repository
Peak flow events and their inherent time scales in rivers are a key aspect of flood studies in hydrology. Yet it is still unclear how often should a river be observed to accurately determine the magnitude and duration of extreme events. This work aims to quantify peak flow event... |

Joao Teixeira, 2024, "Direct Observational Evidence from Space of the Effect of CO2 Increase on Longwave Spectral Radiances: The Unique Role of High Spectral Resolution Measurements", https://doi.org/10.48577/jpl.KC3HAX, Atmospheric Chemistry and Physics, JPL Open Repository
We present a direct measurement of the impact of increased atmospheric CO2 on the spectra of Earth's longwave radiation obtained from space. The goal of this study is to experimentally confirm that the direct effects of CO2 increase on the Earth’s outgoing longwave spectra follow... |

Luis Millan Valle, 2024, "Exploring ozone variability in the upper troposphere and lower stratosphere using dynamical coordinates", https://doi.org/10.48577/jpl.JOV7YW, Atmospheric Chemistry and Physics, JPL Open Repository
Ozone trends in the upper troposphere/lower stratosphere (UTLS) remain highly uncertain because of sharp spatial gradients and large variability caused by competing transport, chemical, and mixing processes near the upper tropospheric jets and extra-tropical tropopause, as well a... |

Eva Peral, 2024, "KaRIn, the Ka-Band Radar Interferometer of the SWOT Mission: Design and In-Flight Performance", https://doi.org/10.48577/jpl.E4FIJH, Transactions of Geosciences and Remote Sensing, JPL Open Repository
The Surface Water and Ocean Topography (SWOT)mission was recommended by the 2007 National Research CouncilDecadal Survey to expand on previous altimetry missionslike TOPEX/Poseidon. Utilizing wide-swath altimetry technology,SWOT aims to achieve complete coverage of the world’s oc... |

Nereida Rodriguez Alvarez, 2024, "Forward and Backward Full-Pol Scattering Analysis using SMAP Datasets", https://doi.org/10.48577/jpl.J2DYYP, Remote Sensing of Environment, JPL Open Repository
Over the past two decades, there has been a growing trend in the utilization of bistatic radar configurations for remote sensing using Signals-of-Opportunity (SoOp), such as Global Navigation Satellite System - Reflectometry (GNSS-R). This GNSS-R forward configuration is dominate... |

Nereida Rodriguez Alvarez, 2024, "Estimating Backward Scattering using GNSSReflectometry Measurements for Soil Moisture Retrieval", https://doi.org/10.48577/jpl.VC3JAC, IEEE Access, JPL Open Repository
Soil Moisture (SM) is a key geophysical variable that enables a better understanding of theEarth’s hydrological processes. Missions like Soil Moisture Ocean Salinity (SMOS) and Soil Moisture ActivePassive (SMAP) have been the primary sources of SM estimations for years. The NASA-... |

Jonathan Jiang, 2024, "How the presence of a giant planet affects the outcome of terrestrial planet formation simulations", https://doi.org/10.48577/jpl.QZVKGK, Astronomy & Astrophysics, JPL Open Repository
The architecture and masses of planetary systems in the habitable zone could be strongly influenced by the presence of outer giant planets. Here, we investigate the impact of outer giants on terrestrial planet formation, under the assumption that the final assembly of the planeta... |

Mike Ressler, 2024, "JWST Observations of Young protoStars (JOYS+): Detection of icy complex organic molecules and ions I. CH4 , SO2 , HCOO− , OCN−, H2 CO, HCOOH, CH3 CH2 OH, CH3 CHO, CH3 OCHO, CH3 COOH", https://doi.org/10.48577/jpl.SLERMD, Astronomy & Astrophysics, JPL Open Repository
Context. Complex organic molecules (COMs) are ubiquitously detected in the gas phase and are thought to be mostly formed on icy grains. Nevertheless, no unambiguous detection of COMs larger than CH3 OH in ices has been reported so far, but exploring this matter in more detail has... |
