Distributions of measured emission rates (logarithmic scale) by region (top) and by fluid type (bottom). Black dots represent individual site-level emission rates. For better visualization of the emission rate distributions, the plots are broken down to show non-emitting sites (left panel, emission rate = 0), and emitting sites (right panels). The box limits are the interquartile ranges (IQR), and whiskers represent the upper (Q3 + 1.5 * IQR) and lower (Q1 − 1.5 * IQR) ranges of non-zero emissions. The orange diamond is the overall mean (emitting and non-emitting) for each subpopulation.
