TAMU TRACER SMPS-POPS Merged Size Distribution

This data is generated using measurements collected during the 2022 DOE ARM TRACER field campaign. Aerosol size distribution data collected by the Scanning Mobility Particle Sizer (SMPS) is merged with data from the Portable Optical Particle Spectrometer (POPS). This merging process involves determining the aerosol refractive index used for POPS sizing to minimize discrepancies in the overlapping portion of the size distributions measured by SMPS and POPS.

本数据集基于2022年美国能源部（Department of Energy, DOE）大气辐射测量（Atmospheric Radiation Measurement, ARM）计划TRACER野外考察期间获取的实测数据生成。研究人员将扫描迁移率粒子粒径谱仪（Scanning Mobility Particle Sizer, SMPS）采集的气溶胶粒径分布数据，与便携式光学粒子谱仪（Portable Optical Particle Spectrometer, POPS）获取的观测数据进行融合。该融合流程需确定用于POPS粒径反演的气溶胶折射率，以最小化SMPS与POPS实测粒径分布重叠区间内的测量偏差。
