    Investigating Carbonaceous Aerosol and Its Absorption Properties From Fires in the Western United States (WE‐CAN) and Southern Africa (ORACLES and CLARIFY) by Carter, Therese S, Heald, Colette L, Cappa, Christopher D, Kroll, Jesse H, Campos, Teresa L, Coe, Hugh, Cotterell, Michael I, Davies, Nicholas W, Farmer, Delphine K, Fox, Cathyrn, Garofalo, Lauren A, Hu, Lu, Langridge, Justin M, Levin, Ezra JT, Murphy, Shane M, Pokhrel, Rudra P, Shen, Yingjie, Szpek, Kate, Taylor, Jonathan W, Wu, Huihui

    Published 2021
    “…Our comparisons suggest that BC and/or BrC absorption is substantially higher downwind of Africa than in the western United States and, while the Saleh et al. (2014, https://doi.org/10.1038/ngeo2220) and FIREX parameterizations based on the BC:OA ratio improve model-observation agreement in some regions, they do not sufficiently differentiate absorption characteristics at short wavelengths. …”

    Sources of productivity growth in the American coal industry by Ellerman, Thomas M., Stoker, Thomas M., Berndt, Ernst R.

    Published 2009
    “…This paper develops new techniques to assess the expanse of the geographic market under varying supply and demand conditions and applies these techniques to the current wholesale electricity market in the western United States. This paper finds that, by and large, the expanse of the geographic market extends across most of the western United States, but that conditions which create congestion along transmission lines, such as high hydroelectric flows in the Pacific Northwest, transmission line outages and deratings, and high demand for wholesale electricity, cause the expanse of the geographic market to narrow at certain times.…”

    Local Community Composition Drives Avian Borrelia burgdorferi Infection and Tick Infestation by Lilly, Marie, Amaya-Mejia, Wilmer, Pavan, Lucas, Peng, Ceili, Crews, Arielle, Tran, Nghia, Sehgal, Ravinder, Swei, Andrea

    Published 2022
    “…These results indicate that birds are relevant hosts in the local <i>B. burgdorferi</i> s.l. transmission cycle in the western United States and quantifying their role in the spread and maintenance of Lyme disease requires further research.…”

    A water rights transfer evaluation procedure with applications for western energy development by Gerstle, John Herman, Marks, David H.

    Published 2006
    “…This report deals with questions of water supply for coal deve- lopment in the semiarid western United States. A method is developed to evaluate yields of water rights in "appropriation" or "permit" systems of water administration. …”

    The impact of bark beetle infestations on monoterpene emissions and secondary organic aerosol formation in western North America by Berg, A. R., Heald, Colette L., Huff Hartz, K. E., Hallar, A. Gannet, Meddens, A. J. H., Hicke, J. A., Lamarque, Jean-Francois, Tilmes, S.

    Published 2013
    “…Over the last decade, extensive beetle outbreaks in western North America have destroyed over 100 000 km2 of forest throughout British Columbia and the western United States. Beetle infestations impact monoterpene emissions through both decreased emissions as trees are killed (mortality effect) and increased emissions in trees under attack (attack effect). …”

    Western U.S. lake expansions during Heinrich stadials linked to Pacific Hadley circulation by McGee, D, Moreno-Chamarro, E, Marshall, J, Galbraith, ED

    Published 2021
    “…Here, we combine data with model simulations to show that maximum winter precipitation anomalies were related to an intensified subtropical jet and a deepened, southeastward-shifted Aleutian Low, which together increased atmospheric river–like transport of subtropical moisture into the western United States. The jet and Aleutian Low changes are tied to the southward displacement of the intertropical convergence zone and the accompanying intensification of the Hadley circulation in the central Pacific. …”

    OH chemistry of non-methane organic gases (NMOGs) emitted from laboratory and ambient biomass burning smoke: evaluating the influence of furans and oxygenated aromatics on ozone an...

    Published 2021
    “…Based on the decay of primary carbon measured by proton transfer reaction time-of-flight mass spectrometry (PTR-ToF-MS), it is confirmed that furans and oxygenated aromatics are among the NMOGs emitted from western United States fuel types with the highest reactivities towards OH. …”

    Secondary organic aerosol formation from the laboratory oxidation of biomass burning emissions by Lim, Christopher Yung-Ta, Hagan, David Henry, Coggon, Matthew M., Koss, Abigail R., Sekimoto, Kanako, de Gouw, Joost, Warneke, Carsten, Cappa, Christopher D., Kroll, Jesse

    Published 2020
    “…As part of the Fire Influence on Regional and Global Environments Experiment (FIREX 2016), we investigated the effect of photochemical aging on biomass burning organic aerosol (BBOA) with a focus on fuels from the western United States. Emissions were sampled into a small (150 L) environmental chamber and photochemically aged via the addition of ozone and irradiation by 254 nm light. …”

    Deciphering Hydrological Responses: Elastic and Poroelastic Behavior Through GPS Temporal Analysis by Sandoe, Lucy A.

    Published 2024
    “…In Chapter 2, in order to accurately understand and quantify the effects of water loading, we use the degree of correlation between the modeled hydrology at each site and the actual GPS station timeseries, then extrapolate spatially, finding areas of higher and lower correlation with elastic deformation across the Western United States. We also study the dates of peak seasonal amplitude throughout the region. …”
