One-year bipolar SMPS observational dataset at China’s atmospheric baseline stations

This dataset contains one-year continuous bipolar SMPS size distribution and particle number concentration observational data collected at China’s nationwide atmospheric baseline stations, supporting the findings presented in the manuscript “Network Observations of PNSD at China’s Nationwide Atmospheric Baseline Stations using bipolar SMPS”. All raw observational files from six monitoring sites are included. Associated data quality control, analysis and plotting codes are also provided. The dataset will be publicly available with a permanent DOI upon publication.
