Aerosol sampling for chemical analysis in JARE62

Aerosol samling was performed for chemical analysis using impactor with pack-up filter and high volume air sampler. To avoid local contamination, aerosol sampling was controlled by wind selector.为开展化学分析，本研究采用搭载备用滤膜（pack-up filter）的冲击式采样器（impactor）与大流量空气采样器（high volume air sampler）完成气溶胶采样。为避免局部污染，气溶胶采样过程通过风选装置（wind selector）进行管控。
