Dataset for combined influences of sources and atmospheric bleaching on light absorption of water-soluble brown carbon aerosols

This dataset provides the mass-absorption cross section at 365 nm and the corresponding absorption Ångström exponent, carbon isotope (13C and 14C) signature of water-soluble organic carbon, and OC, EC and WS-BrC concentration for aerosol samples collected in East Asia. The PM2.5 samples were collected simultaneously during the winter period (January 2014) from the representative hotspot regions of BrC emissions in E. Asia, including in the Beijing-Tianjin-Hebei (BTH) area, Yangtze River Delta (YRD), Pearl River Delta (PRD), Sichuan (SC) province and SE Yellow Sea regional receptor site — the Korea Climate Observatory at Gosan (KCOG). The earlier published data in E. and S. Asia, such as KCOG, urban city Delhi, Bangladesh Climate Observatory at Bhola Island (BCOB) in the outflow region of the Indo-Gangetic Plain and Maldives Climate Observatory at Hanimaadhoo Island (MCOH) in the Indian Ocean are from corresponding references (see the annotation in each sheet).
