Fig. 2: CH3Br emissions inferred from atmospheric observations and inversion.
From: Unexplained high and persistent methyl bromide emissions in China
a CH3Br emissions in all of China and eastern China. The shaded area represents 1-sigma uncertainties. b Spatial distribution of average CH3Br emissions during 2011−2020. Eastern China (enclosed with red lines) shows the highest emission rate per unit area in China. The hatched areas represent regions to which our observations have low sensitivity and are excluded from the emission estimates in this study. The magenta triangles and yellow dots represent the locations with reported illegal productions and sales of CH3Br in China between 2010 to 201429,30,31,32,33,34 and in 202035,36, respectively.
