Table 1. MAC values and ratios calculated with Mie theory^a.

Index of refraction	(2.26, −1.26)	(2.26, −1.26)	(2, −1)	(2.26, −1.26)
Wavelength, nm	550	500	550	460
Urban MAC, m² g⁻¹	7.1	7.7	6.2	8.35
Remote/urban atmosphere ratio	0.97	0.92	0.94	0.88
First-melt snow/urban ratio	0.67	0.63	0.67	0.58

^aThe ratios of refractory BC MAC calculated for remote or first-melt snow size distributions to that calculated from the urban size distribution (CalNex). The calculation was repeated with different values for absorbing wavelength and the index of refraction of bare BC spheres in Mie theory. The right-most column represents our best estimate.
