From: California dominates U.S. emissions of the pesticide and potent greenhouse gas sulfuryl fluoride
Panel (a) shows a frequency histogram of GGGRN observations <5.0 ppt (bin size = 0.25 ppt). Panel (b) shows a frequency histogram of GGGRN observations >10.0 ppt (bin size = 10.0 ppt). The vertical dotted and dashed lines indicate the mean and median observed values, respectively.
