“…As κ Org of SOA from limonene +NO 3 can be approximated to be equal to the κ ON , κ ON from limonene +NO 3 (0.038 ± 0.01) was close to κ ON from limonene OH oxidation (0.038 ± 0.07). Generally, κ ON from monoterpene oxidation is lower than the κ Org (around 0.1) of non‐ON MT‐SOA (Alfarra et al., 2013; Bouzidi et al., 2022), independent if the SOA was formed by ozonolysis or OH oxidation. The lower κ ON compared to κ non‐ON Org may be attributed to the generally higher molecular weight and thus higher partial molar volume with the same carbon matrix, and less polarity of nitrate group compared to hydroxyl and hydroperoxyl groups.…”

Organic matters are important components of aerosols in the atmosphere making up a large fraction (20%-90%) of the submicron particulate mass (Jimenez et al., 2009;Zhang et al., 2007). Organic aerosols influence the climate (Kanakidou et al., 2005) by contributing to aerosol-radiation interactions and aerosol-cloud interaction (Kuniyal & Guleria, 2019). According to the 6th assessment report by IPCC (IPCC, 2021), the latter still has large uncertainties, which are related to uncertainties in the challenging prediction of concentration of cloud condensation nuclei (CCN). Organic aerosols are often of secondary nature (secondary organic aerosols, SOA) (Zhang et al., 2007). On global scale, the production rate of biogenic SOA (BSOA) is much higher than anthro-

“…There are a couple of potential reasons for the size dependence in κ . One possibility is the size‐dependent chemical composition of particles, which is associated with nucleation/condensation processes (Bouzidi et al., 2022). Chemical species that could involve in nucleation need to be of sufficiently low volatility for overcoming the energy barrier for nucleation (Kulmala, 2003).…”

Roles of Relative Humidity and Particle Size on Chemical Aging of Tropical Peatland Burning Particles: Potential Influence of Phase State and Implications for Hygroscopic Property

et al. 2022

Peatland fires in Southeast Asia are an important source of primary organic aerosol (POA). Chemical aging of POA in the atmosphere produces oxygenated POA (OPOA). The OPOA production influences optical and hygroscopic properties, modulating the regional climate. However, the roles of environmental parameters such as relative humidity (RH) on chemical aging of peatland burning particles have rarely been investigated. Utilizing the potential aerosol mass (PAM) reactor, we conducted laboratory experiments for POA aging of particles generated from smoldering combustions of surface peat, fern, and Acacia leaves. The corresponding experiments for secondary organic aerosol formation were also separately conducted. Properties and chemical compositions of the resulting particle were quantified by both the hygroscopic tandem differential mobility analyzer and time‐of‐flight aerosol chemical speciation monitor (ToF‐ACSM). Conversion of peat combustion from POA to OPOA was pronounced when RH in the PAM reactor was higher. Considering that previous electromicroscopic observations demonstrated that peat combustion POA is likely (semi)solid, we postulate that oxidation of fresh peatland burning particles is faster at an elevated RH due to reduced viscosity following hygroscopic growth. Hygroscopicity parameter (κ) of aged POA particles linearly correlated with the mass fraction of OPOA that was quantified by the ToF‐ACSM. The above results highlight the importance of simultaneously measuring the chemical aging and particle phase state of peatland burning POA for quantifying their climatic impacts.

Abstract. This study employed multiple techniques to investigate the contribution of grown new particles to the number concentration of cloud condensation nuclei (CCN) at various supersaturation (SS) levels at a rural mountain site in North China Plain from 29 June to 14 July 2019. On eight new particle formation (NPF) days, the total particle number concentrations (Ncn) were 8.4±6.1 ×103 cm-3, which were substantially higher compared to 4.7±2.6 ×103 cm-3 on non-NPF days. However, the Nccn at 0.2 %SS and 0.4 %SS on the NPF days were significantly lower than those observed on non-NPF days (P<0.05). This was due to the lower cloud activation efficiency of pre-existing particles resulting from organic vapor condensation and smaller number concentrations of pre-existing particles on NPF days. A case-by-case examination showed that the grown new particles only yielded a detectable contribution to Nccn at 0.4 % SS and 1.0 % SS during the NPF event on 1 July 2019, accounting for 12±11 % and 23±12 % of Nccn, respectively. The increased Nccn during two other NPF events and at 0.2 % SS on 1 July 2019 were detectable, but determined mainly by varying pre-existing particles rather than grown new particles. In addition, the hygroscopicity parameter values, concentrations of inorganic and organic particulate components, and surface chemical composition of different sized particles were analyzed in terms of chemical drivers to grow new particles. The results showed that the grown new particles via organic vapor condensation generally had no detectable contribution to Nccn, but incidentally did. However, this conclusion was drawn from a small size of observational data, leaving more observations, particularly for long-term observations and the growth of pre-existing particles to the CCN required size, needed for further investigation.
