Figure 1
Ensemble modeled and observed trends of sulfate in aerosols over the period 1990–2015 compared to the trend in emissions over the same period. The upper left panel includes a striped green part indicating possible overestimated emissions in China, and the dotted black line in the East Asia panel shows an alternative emission trend adjusted from more recent inventories18,20. The time series show the annual values for years given. The uncertainty is illustrated using the standard deviation of the bootstrap trend for each region.
