MAC data are divided based on the absorption measurement technique (a and c, left panels: photoacoustic, b and d, right panels: filter photometers. The latter includes any technique in which a filter is used, see Table 2, including Aethalometers, PSAP, CLAP, MAAP, COSMOS, and optical measurement in TOA analysis). MAC data are further grouped based on mass reference in a and b, and by aerosol type in c and d, to represent remote, urban, and mixed aerosol.
