Fig. 1: Map of the satellite-based annual average anthropogenic sulfur dioxide (SO2) emissions across Asia from 1990 to 2016 (data source: MERRA-2 Reanalysis M2TMNXADG v5.12.4).
From: Coral records indicate six-decade rise and fall of atmospheric lead emission in China
This map shows that eastern China, due to its soaring economic development and urbanization, has been dominating the regional SO2 emissions in the past decades. The emitted SO2 and its accompanying trace metals can influence the atmospheric depositions at downwind sites, including Dongsha Atoll, South China Sea. The circle marks our study ___location, the Dongsha Atoll. Other study sites of published coral records in the region are also shown: Nha Trang23 (triangle) and Phuket22 (square).
