15 Volatile organic compounds (VOCs) are important precursors for the formation of ground-level 16 ozone. In this study, the hourly mixing ratio of 61 ambient VOCs species was measured from 2018 17 to 2019 in 10 cities in Beijing-Tianjin-Hebei (BTH) area in China. The VOCs distribution, 18 speciation and photochemical implications also was discussed in this study. The cities with the 19 highest mixing ratio of VOCs were in the southern part as LF, BD, HD and SJZ, while the CD and 20 ZJK were
