“…Fossil fuel burning was reported to be an important contributor across large areas of the Asian continent, especially in the fast developing regions of China and Southeast Asia (Russo et al, 2003;Woo et al, 2003). In East Asia, transport from South Korea and Japan is also depicted in the regional emissions Carmichael et al, 2003).…”

Abstract.A strong pollution episode in the upper troposphere between South China and the Philippines was observed during CARIBIC flights in April 2007. Five pollution events were observed, where enhancements in aerosol and trace gas concentrations including CO, CO 2 , CH 4 , nonmethane hydrocarbons (NMHCs) and halocarbons were observed along the flight tracks during four sequential flights. The importance of the contribution of biomass/biofuel burning was investigated using chemical tracers, emission factor analysis, back-trajectory analysis and satellite images. The Indochinese peninsula was identified as the probable source region of biomass/biofuel burning. However, enhancements in the urban/industrial tracer C 2 Cl 4 during the events also indicate a substantial contribution from urban anthropogenic emissions. An estimation of the contribution of fossil fuel versus biomass/biofuel to the CO enhancement was made, indicating a biomass/biofuel burning contribution of ∼54 to ∼92% of the observed CO enhancements. Biomass/biofuel burning was found to be the most important source category during the sampling period.

“…Considering the mentioned satellite fire map, higher contributions of biomass burning in this case would be expected. Woo et al (2003) reported that biofuel emissions were more strongly correlated with fossil fuel emissions than biomass burning. Here the correlation between CH 3 Cl and C 2 Cl 4 is obtained.…”

“…The following sections explain how we modeled each of these processes. We modeled the aerosol dynamics within the plume with the Particle Monte Carlo (PartMC) model (Riemer et al, 2009) coupled to the Model for Simulating Aerosol Interactions and Chemistry (MOSAIC) (Zaveri et al, 2008). PartMC-MOSAIC is a box model that tracks the composition of individual particles within a Lagrangian air parcel as they evolve due to Brownian coagulation, condensation and evaporation (i.e., gas-particle partitioning), chemical reactions, and dilution.…”

“…PartMC-MOSAIC is a box model that tracks the composition of individual particles within a Lagrangian air parcel as they evolve due to Brownian coagulation, condensation and evaporation (i.e., gas-particle partitioning), chemical reactions, and dilution. Whereas coagulation and dilution are modeled as stochastic processes with a Poisson distribution, MOSAIC simulates the gas and particle-phase thermodynamics, and gas-particle mass transfer (Riemer et al, 2009;Zaveri et al, 2008). MOSAIC uses the SORGAM scheme to model the formation of low-volatility and semi-volatile products from the oxidation of precursors, and their gas-particle partitioning (Schell et al, 2001;Zaveri et al, 2010).…”

Plume-exit modeling to determine cloud condensation nuclei activity of aerosols from residential biofuel combustion

2017

Abstract. Residential biofuel combustion is an important source of aerosols and gases in the atmosphere. The change in cloud characteristics due to biofuel burning aerosols is uncertain, in part, due to the uncertainty in the added number of cloud condensation nuclei (CCN) from biofuel burning. We provide estimates of the CCN activity of biofuel burning aerosols by explicitly modeling plume dynamics (coagulation, condensation, chemical reactions, and dilution) in a young biofuel burning plume from emission until plume exit, defined here as the condition when the plume reaches ambient temperature and specific humidity through entrainment. We found that aerosol-scale dynamics affect CCN activity only during the first few seconds of evolution, after which the CCN efficiency reaches a constant value. Homogenizing factors in a plume are co-emission of semi-volatile organic compounds (SVOCs) or emission at small particle sizes; SVOC co-emission can be the main factor determining plume-exit CCN for hydrophobic or small particles. Coagulation limits emission of CCN to about 10 16 per kilogram of fuel. Depending on emission factor, particle size, and composition, some of these particles may not activate at low supersaturation (s sat ). Hygroscopic Aitken-mode particles can contribute to CCN through self-coagulation but have a small effect on the CCN activity of accumulation-mode particles, regardless of composition differences. Simple models (monodisperse coagulation and average hygroscopicity) can be used to estimate plume-exit CCN within about 20 % if particles are unimodal and have homogeneous composition, or when particles are emitted in the Aitken mode even if they are not homogeneous. On the other hand, if externally mixed particles are emitted in the accumulation mode without SVOCs, an average hygroscopicity overestimates emitted CCN by up to a factor of 2. This work has identified conditions under which particle populations become more homogeneous during plume processes. This homogenizing effect requires the components to be truly co-emitted, rather than sequentially emitted.

Although there has been much progress in measuring the physical and optical properties of dust and non-dust aerosols (Cao et al, 2014;Jing et al, 2015), the monthly and seasonal variations in these aerosols have yet to be well quantified, especially across the Loess Plateau, near the dust sources.…”

We analyzed the suspended particle size distribution in the range of 0.5 to 10 µm and the optical properties of the particles from March 2007 to December 2010 at a site on the Loess Plateau (SACOL; 35.57°N, 104.08°E; 1965.8 m a.s.l.) about 48 km southeast of the center of Lanzhou. The results indicated that the variation in PM 10 was much larger in spring than in winter because of frequent dust events or local blowing soil dust during spring. The highest number concentrations of coarse-mode particles were likely attributable to dust events that transported mineral dust or soil dust in the spring season, caused by cold fronts or strong local winds. In contrast, the fine-mode particles that dominated in the cold season at SACOL were probably indicative of anthropogenic sources related to fossil-fuel combustion and biomass burning. The comparison of dust events and anthropogenic air pollution shows a clear distinction of lower PM 10 with higher B ap for pollution episodes and higher PM 10 with lower B ap for dust events. These findings suggest that the results in the cold season were likely attributable to light absorption of black carbon, and the coarse mode particles were dominant during dust events in spring.
