Christine Lee, 2020, "ECOSTRESS and CIMIS: A Comparison of Potential and Reference Evapotranspiration in Riverside County, California", https://doi.org/10.48577/jpl.RBKCRG, Remote Sensing, JPL Open Repository
The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) provides remotely-sensed estimates of plant water use, demand, and stress at 70 m spatial resolution every 1–5 days, sampling across the diurnal cycle. This study, in partnership with an operation... |

Fisher, Joshua B, 2020, "Once upon a time, in AmeriFlux", https://doi.org/10.48577/jpl.OL7ACP, Journal of Geophysical Research, JPL Open Repository
In October 2020, under COVID-19 quarantine, AmeriFlux held its largest and one of its most successful annual meetings . Historically, ~100 scientists attend; this meeting had over 400 registrants and participants. Participants expressed that this was among the best virtual meetin... |

Fisher, Joshua B, 2020, "Integrating Field Observations and Reactive Transport Modeling to Predict Watershed Water Quality under Environmental Perturbations", https://doi.org/10.48577/jpl.AW9SDR, Journal of Hydrology, JPL Open Repository
Watersheds play a critical role in supplying water resources needed for humanuse and ecosystem health. Understanding and predicting how, when,and where changes in the quantity and quality of water resources occur underdierent environmental stresses including extreme events is cr... |

Fisher, Joshua B, 2020, "Root-derived inputs are major contributors to soil carbon in temperate forests, but vary by mycorrhizal type", https://doi.org/10.48577/jpl.STJTR6, Ecology Letter, JPL Open Repository
Roots promote the formation of slow-cycling soil carbon (C), yet we have limited understanding of the magnitude and controls on this flux. We hypothesized arbuscular mycorrhizal (AM)- and ectomycorrhizal (ECM)-associated trees would exhibit differences in root-derived C accumulat... |

Fisher, Joshua B, 2020, "Beyond Ecosystem Modeling: A Roadmap to Community Cyberinfrastructure for Ecological Data-Model Integration", https://doi.org/10.48577/jpl.HUJACV, Global Change Biology, JPL Open Repository
In an era of rapid global change, our ability to understand and predict Earth's natural systems is lagging behind our ability to monitor and measure changes in the biosphere. Bottlenecks to informing models with observations have reduced our capacity to fully exploit the growing... |

Fisher, Joshua B, 2020, "Integrating the evidence for a terrestrial carbon sink caused by increasing atmospheric CO2", https://doi.org/10.48577/jpl.YX52GI, New Phytologist, JPL Open Repository
Photosynthesis uses the energy in sunlight to bind CO2 to a five-carbon sugar, transferring CO2 from the atmosphere to plants (Calvin & Benson, 1948; Farquhar et al., 1980). Sugars produced by photosynthesis provide the building blocks and the primary fuel for much of life on Ear... |

Fisher, Joshua B, 2020, "Modeling suggests fossil fuel emissions have been driving increased land carbon uptake since the turn of the 20th Century", https://doi.org/10.48577/jpl.NYUE36, Scientific Reports, JPL Open Repository
Terrestrial vegetation removes CO2 from the atmosphere; an important climate regulation service that slows global warming1. This 119 Pg C per annum transfer of CO2 into plants2—gross primary productivity (GPP)—is the largest land carbon flux globally. While understanding past and... |

Fisher, Joshua B, 2020, "Global Trends in Evapotranspiration Dominated by Increases Across Large Cropland Regions", https://doi.org/10.48577/jpl.XMHRGC, Remote Sensing, JPL Open Repository
Irrigated croplands require large annual water inputs and are critical to global food production. Actual evapotranspiration (AET) is a main index of water use in croplands, and several remote-sensing products have been developed to quantify AET at the global scale. In this study,... |

Fisher, Joshua B, 2020, "ECOSTRESS: NASA’s next generation mission to measure evapotranspiration from the International Space Station", https://doi.org/10.48577/jpl.CYXICV, Water Resources Research, JPL Open Repository
The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) was launched to the International Space Station on June 29, 2018. The primary science focus of ECOSTRESS is centered on evapotranspiration (ET), which is produced as level-3 (L3) latent heat flux... |
