The highest contribution of HULIS-C to WSOC was observed to be in the particle size bins of 0.55–1.0 μm and 1.8–3.1 μm during non-Asian dust (NAD, 45 ± 6%) and Asian dust (AD, 44 ± 7%) periods, respectively. HULIS exhibited a uni-modal (@0.55 μm) distribution during the NAD and a bimodal distribution (@0.32 and 1.8 μm) during AD, respectively.
