Nereida Rodriguez Alvarez, 2024, "Unlocking the Potential of Graph Signal Processing: Enhancing SMAP Soil Moisture Estimates with SMAP-Reflectometer Data", https://doi.org/10.48577/jpl.SKTRVC, Remote Sensing, JPL Open Repository
The Soil Moisture Active Passive (SMAP) mission has greatly contributed to the use of remote sensing technologies for observing the Earth’s land surface and estimating geophysical parame-ters that influence the climate system. Since the SMAP mission switched its radar receiver to... |

Peter Eisenhardt, 2024, "The Massive and Distant Clusters of WISE Survey 2: Equatorial First Data Release", https://doi.org/10.48577/jpl.2SCCXX, The Astrophysical Journal, JPL Open Repository
The Massive and Distant Clusters of WISE Survey 2 (MaDCoWS2) is a new survey designed as the successor of the original MaDCoWS survey. MaDCoWS2 improves upon its predecessor by using deeper optical and infrared data and a more powerful detection algorithm (PZWav). As input to the... |

Nicholas Parazoo, 2024, "Antecedent Conditions Mitigate Carbon Loss During Flash Drought Events", https://doi.org/10.48577/jpl.FNXCXH, Geophysical Research Letters, JPL Open Repository
Flash droughts– the rapid drying of land and intensification of drought conditions - have devasting impacts to natural resources, food supplies, and the economy. Less is currently known about the drivers of flash droughts and their impact to landscape carbon losses. We leverage c... |

Anthony Bloom, 2024, "Inferred drought-induced plant allocation shifts and their impact on drought legacy at a tropical forest site", https://doi.org/10.48577/jpl.AKNCT9, Global Change Biology, JPL Open Repository
While droughts predominantly induce immediate reductions in plant carbon uptake, they can also exert long-lasting effects on carbon fluxes through associated changes in leaf area, soil carbon, etc. Among other mechanisms, shifts in carbon allocation due to water stress can contri... |

Anthony Bloom, 2024, "Interpreting the seasonality of atmospheric methane", https://doi.org/10.48577/jpl.NQPWKI, Geophysical Research Letters, JPL Open Repository
Surface and satellite observations of atmospheric methane show smooth seasonal behavior in the Southern Hemisphere driven by loss from the hydroxyl (OH) radical. However, observations in the Northern Hemisphere show a sharp mid-summer increase that is asymmetric with the Southern... |

Klaus Pontoppidan, 2024, "A Cavity in the Compact Disk of the Forming Companion GQ Lup B Revealed by JWST/MIRI", https://doi.org/10.48577/jpl.BCQOB4, The Astrophyscial Journal, JPL Open Repository
GQ Lup B is a forming brown dwarf companion ($M\sim10-30~\MJ$) showing evidence for an infrared excess associated with a disk surronding the companion itself. Here we present mid-infrared (MIR) observations of GQ~Lup~B with the Medium Resolution Spectrograph (MRS) on JWST, spanni... |

Bonnie Buratti, 2024, "Pre-impact albedo map and photometric properties of the (65803) Didymos asteroid binary system from DART and ground-based data", https://doi.org/10.48577/jpl.KVMNJB, Planetary Science Journal, JPL Open Repository
This study provides a pre-impact map of the albedo of the Double Asteroid Redirection Test (DART) target Dimorphos corrected for all the effects of viewing geometry, as well as an estimate of photometric roughness for the hemisphere imaged by DART. Other photometric properties ar... |

Catherine Elder, 2024, "Rocks with extremely low thermal inertia at the OSIRIS-REx sample site on asteroid Bennu", https://doi.org/10.48577/jpl.DOLOBK, Planetary Science Journal, JPL Open Repository
The OSIRIS-REx mission recently returned a sample of rocks and dust collected from asteroid Bennu. We analyzed the highest-resolution thermal data obtained by the OSIRIS-REx Thermal Emission Spectrometer (OTES) to gain insight into the thermal and physical properties of the sampl... |

James Wallace, 2024, "Keck Primary Mirror Closed-Loop Segment Control using a Vector-Zernike Wavefront Sensor", https://doi.org/10.48577/jpl.C5BJFP, The Astrophysical Journal Letters, JPL Open Repository
We present the first on-sky segmented primary mirror closed-loop piston control using a Zernike wavefront sensor (ZWFS) installed on the Keck II telescope. Segment co-phasing errors are a primary contributor to contrast limits on Keck and will be necessary to correct for the next... |
