Paul Goldsmith, 2024, "Long-term Integration Ability of the SubmillimeterWave Astronomy Satellite (SWAS) Spectral Line Receivers", https://doi.org/10.48577/jpl.KR15HL, Research in Astronomy and Astrophysics, JPL Open Repository
The Submillimeter Wave Astronomy Satellite (SWAS) was the first space telescope capable of high spectral resolution observations of terahertz spectral lines. We have investigated the integration ability of its two receivers and spectrometer during five and a half years of on-orbi... |

Davide Farnocchia, 2024, "Mass, density, and radius of asteroid (16) Psyche from high-precision astrometry", https://doi.org/10.48577/jpl.WYXOBW, Astronomical Journal, JPL Open Repository
We characterize asteroid (16) Psyche using high-precision astrometry, including the recent Gaia Focused Data Release. The gravitational perturbations of Psyche on other asteroids can be observable in case of mutual encounters. Using a least squares approach, we estimate the mass... |

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... |

Juan Socuellamos, 2024, "A G-band Doppler Radar for Atmospheric Profiling", https://doi.org/10.48577/jpl.YHO3KV, IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING, JPL Open Repository
The development of radar systems operating at G-band (110 - 300 GHz) with small size, weight, and power requirements can offer new possibilities for probing clouds and precipitation from space and lead to novel mission concepts. To advance the technology needed to achieve such ob... |

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... |
