  1. Ambient, biomass burning-dominated and BC with coating removed rows summarize the data in Fig. 3c. The filter photometer and photoacoustic rows correspond to Fig. 3a, with the respective rows under each category corresponding to the panels in the bottom row of Fig. 4. Means and standard deviations are unweighted by the uncertainties in their respective studies, as the spread in the data is a better indication of the spread across the studies.
  2. aVery limited data was available for this row.
