Fine particle concentration during the MR22-06C cruise of R/V Mirai

Fine aerosol particle number concentration data obtained from the R/V Mirai cruise in 2022 (MR22-06C), which were continuously measured using a scanning mobility particle sizer (SMPS; Nano scan SMPS3910, TSI Inc.) located in an experimental room on the flying bridge. Ambient air was drawn through ~3-m-long tube and then was dried by a Nafion-type aerosol dryer placed in front of SMPS to avoid the condensation of water inside the tubing and instrument and to sample "completely dried" particles.本数据集为2022年R/V Mirai号科考船航次（航次编号MR22-06C）所获取的细气溶胶粒子数浓度数据。该数据由安装于飞桥实验舱的扫描迁移率粒径谱仪（scanning mobility particle sizer, SMPS；型号为Nano scan SMPS3910，TSI公司生产）连续测定得到。环境空气经约3米长的采样管路被抽取，随后通过置于SMPS前端的纳菲昂（Nafion）型气溶胶干燥器进行干燥处理，以避免水汽在管路及仪器内部冷凝，并采集“完全干燥”的气溶胶粒子。
