Abstract We present an analysis of methane (CH 4 ) emissions using atmospheric observations from 13 sites in California during June 2013 to May 2014. A hierarchical Bayesian inversion method is used estimate CH for spatial regions (0.3° pixels major regions) by comparing measured mixing ratios with transport model (Weather Research and Forecasting Stochastic Time‐Inverted Lagrangian Transport) predictions based on seasonally varying California‐specific prior emission models. The assessed a...
Abstract This work presents techno‐economic and greenhouse gas (GHG) analyses of an ethanol biorefinery integrating lignin conversion into eugenol other phenolics. Catalytic hydrogenolysis assisted by isopropanol (IPA) is used to convert the recovered after ionic liquid (IL) pretreatment, saccharification, fermentation. process was compared a using for energy generation simulated in SuperPro Designer. Spatial analysis performed determine locations capacities Mexican state with potential...

Analysis systems incorporating atmospheric observations could provide a powerful tool for validating fossil fuel CO2 (ffCO2) emissions reported individual regions, provided that sources can be separated from other or sinks and transport accurately accounted for. We quantified ffCO2 by measuring radiocarbon (14C) in CO2, an accurate fossil-carbon tracer, at nine observation sites California three months 2014–15. There is strong agreement between the measurements simulated using...
Abstract Crop yield modeling is critical in the design of national strategies for agricultural production, particularly context a changing climate. Forecasting yields bioenergy crops at fine spatial resolutions can help to evaluate near‐term and long‐term pathways scaling up bio‐based fuel chemical understanding impacts abiotic stressors such as severe droughts temperature extremes on potential biomass supply. We used large dataset 28,364 Sorghum bicolor samples (uniquely identified by...
Studying airflow characteristics in the human respiratory system is important for understanding properties of aerosol transport and deposition. This study first constructed a whole-lung airway model (WLAM) with random features extending from mouth to 13th generation bronchus. The large eddy simulation method utilized investigate both averaged fields flow unsteadiness under inspiratory rates 15 30 l/min, respectively. results reveal following novel findings: (1) secondary strength not...
Abstract We present the first sector‐specific analysis of methane (CH 4 ) emissions from San Francisco Bay Area (SFBA) using CH and volatile organic compound (VOC) measurements six sites during September – December 2015. apply a hierarchical Bayesian inversion to separate biological fossil‐fuel (natural gas petroleum) sources selected VOCs, source‐specific 1 km emission model, an atmospheric transport model. estimate that SFBA are 166–289 Gg /yr (at 95% confidence), 1.3–2.3 times higher than...
Three-dimensional computational fluid dynamic (CFD) methods were used to simulate a cough jet that contains droplets. The turbulent flow is modelled using large-eddy simulation with structure model. An Eulerian–Lagrangian approach was adopted model the two-phase flows. Droplet breakup, evaporation, dispersion and drag forces considered in Two different inlet velocity profiles, which are based on constant mouth opening area variable area, CFD numerical validated by comparing available...
Abstract Atmospheric inverse estimates of gas emissions depend on transport model predictions, hence driving a need to assess uncertainties in the model.
