A gridded organic aerosol dataset for the Beijing–Tianjin–Hebei and Yangtze River Delta regions during 2010–2020

This dataset contains annual mean organic aerosol concentrations simulated by the regional air quality model CAMx version 7.2 (Ramboll, http://www.camx.com/) with a modified VBS scheme for 2010-2020. The data include total organic aerosol (OA), primary organic aerosol (POA), and secondary organic aerosol (SOA) over two regional domains in China: the Beijing-Tianjin-Hebei (BTH) region and surrounding areas, and the Yangtze River Delta (YRD) region and surrounding areas.
