Alyn Lambert, 2024, "The Spread of the Hunga Tonga H 2 O Plume in the Middle Atmosphere Over the First Two Years Since Eruption", https://doi.org/10.48577/jpl.MSVYNZ, Geophysical Research Letters, JPL Open Repository
The eruption of Hunga in January 2022 injected a large amount of water into the stratosphere. Satellite measurements from Aura Microwave Limb Sounder (MLS) show that this water vapor (H2O) has now spread throughout the stratosphere and into the lower mesosphere, resulting in an i... |

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... |

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... |

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... |
