Results of individual particle analysis for INP, PBA, and aerosol observed during MR22-06C

Results of individual particle analysis of ice nucleation particle (INP), primary biological aerosol (PBA), and aerosol observed during R/V Mirai cruise 2022 (MR22-06C). Aerosol particles were collected on the TEM Cu grids (200 mesh) with a Formvar film and Lacey nets (U1007 and U1001, EM Japan) using a three-stage impactor (MPS-3, California Measurements) at the compass deck. The flow rate was 2 LPM, and sampling durations were between 10 and 20 minutes depending on the aerosol concentrations. The collected size ranges were >2 micro-m, 0.3-2 micro-m, and 0.05-0.3 micro-m, respectively. Individual INP was investigated using TEM grid samples by an optical microscope (Axio imager M2m, Zeiss) coupled with a cool stage (10002L, LINKAM) at Meteorological Research Institute (MRI). Then, individual aerosol (including INP and PBA) particle features were analyzed by SEMs (Quanta 450 FEG, FEI and SU-3500, Hitachi High Technologies) and a TEM (TECNAI G2 20, FEI) with EDSs (Octane Elite 30, EDAX, E-max 50 mm, Horiba, and EDAX EDS, EDAX) at MRI and JAMSTEC. It is recommended to contact the investigators for any use.本数据集为“未来”号研究船（R/V Mirai）2022年科考航次（MR22-06C）期间观测得到的冰核粒子（ice nucleation particle, INP）、一次生物气溶胶（primary biological aerosol, PBA）以及各类气溶胶的单颗粒分析结果。气溶胶粒子通过三级撞击器（MPS-3，California Measurements）在罗盘甲板采集，采样载体为覆有Formvar膜与莱西网（U1007、U1001，EM Japan）的透射电子显微镜（Transmission Electron Microscopy, TEM）铜网（200目）。采样流量为2升每分钟（LPM），采样时长根据气溶胶浓度而定，介于10至20分钟之间。本次采集的气溶胶粒径分级依次为＞2微米、0.3~2微米及0.05~0.3微米。在气象研究所（Meteorological Research Institute, MRI），科研人员借助搭载冷台（10002L，LINKAM）的光学显微镜（Axio imager M2m，蔡司Zeiss）对TEM铜网样品中的单颗冰核粒子进行观测分析。随后，在MRI与日本海洋研究开发机构（Japan Agency for Marine-Earth Science and Technology, JAMSTEC），科研人员使用扫描电子显微镜（Scanning Electron Microscope, SEM，复数形式SEMs；型号包括Quanta 450 FEG，FEI与SU-3500，日立高新技术Hitachi High Technologies）及透射电子显微镜（TEM；型号为TECNAI G2 20，FEI），搭配能谱仪（Energy Dispersive X-ray Spectroscopy, EDS；型号包括Octane Elite 30，EDAX、E-max 50 mm，Horiba及EDAX EDS，EDAX）对各类气溶胶（包含INP与PBA）的单颗粒特征展开分析。若需使用本数据集，建议先行联系课题研究人员。
