According to Tegen et al., Heinold et al., ! the radius boundaries of the first seven bins are ! at 0.1, 0.3, 0.9, 2.6, 8.0, 24, 72, and 220 um. ! However, these number don't seem to be exact. ! Since there is a constant ratio between the right ! and low boundaries, it seems this ratio is 3.0. ! Indeed, in Laurent et al. (JGR, 2010), ! 2.6 is corrected to 2.7, which would be consistent ! with 8.0/3.0 = 2.67. ! This would imply that the radius boundaries are at ! 0.0987654 = 72./(3.^6), 0.296296, 0.889, 2.67, 8.0, 24, 72, 216, ! and 648 um. ! Next, each bin is discretized with 24 size points, ! where d(n+1) = d(n) * exp(Dstep). ! Thus, Dstep = ln(3.)/24 = 0.04577551202. ! Dmin is the diameter of the first size point, ! given by 2* 72./(3.^6)) * exp(0.5*Dstep) = 0.20210403762 um. ! Similarly, the last size point is at a diameter ! 2* 648. * exp(-0.5*Dstep) = 1266.67434757 um. ! !

The code follows the ECHAM-HAM implementation ! of Stier et al. (JGR, 2005), ! where the emission distribution is ! fitted onto three log-normal modes ! corresponding to the accumulation, coarse and super-coarse mode. ! (see presentation E. Vignati, TM meeting, 6 June 2008). ! ! According to Heinold et al., ! the three largest dust bins ! are less important for long-range transport, ! so particles with radius larger than 24 um ! can safely be neglected. ! However, a substantial part of the emitted mass ! is carried by particles with a radius larger than 10 um ! (see Tegen et al., Table 5). ! ! The amounts of mass emitted in the accumulation and coarse modes ! are calculated from the masses emitted in the bin model, ! using two size ranges: ! r1 from 0.0987654 to 0.296296 um, and ! r2 from 0.296296 to 8.0 um. ! ! Boundaries for Acc. mode INTEGER, PARAMETER :: min_ai=1 INTEGER, PARAMETER :: max_ai=1 ! Boundaries for Coa. mode INTEGER, PARAMETER :: min_ci=2 INTEGER, PARAMETER :: max_ci=4 ! !

Applying this formula, ! we find the following numbers: ! mf_acc(0,0.0987654)=0.00219913 ! mf_acc_r1=mf_acc(0.0987654,0.296296)=0.313758 ! mf_acc_r2=mf_acc(0.296296,8.0)=0.684043 ! mf_acc(0.296296,inf)=0.684043 ! ! mf_coa(0,0.296296)=0.00519991 ! mf_coa_r1=mf_coa(0.0987654,0.296296)=0.00518309 ! mf_coa_r2=mf_coa(0.296296,8.0)=0.980634 ! mf_coa(8.0,inf)=0.0141665 !

Most importantly, r1 contains only about 31.4% ! of the mass in the accumulation mode! ! This implies that we cannot just put the emissions ! from r1 to the accumulation mode, ! and those from r2 to the coarse mode! ! ! Instead, the modal emissions are determined ! by the following system of linear equations: ! mf_acc_r1 * flux_ai + mf_coa_r1 * flux_ci = flux_r1 ! mf_acc_r2 * flux_ai + mf_coa_r2 * flux_ci = flux_r2, ! which relates the mass emitted in the ranges r1 and r2 ! to the mass emitted in the accumulation and coarse modes. !

Source mass median radius (cm) ! Stier et al. (2005) uses very similar numbers ! for mass median radii, ! but uses 0.37 um for the accumulation mode. !

The AeroCom recommendation of Dentener et al. (ACP, 2006) ! is to use a number median radius ! of 0.65 um for the coarse mode, ! which corresponds to mass median radius of 2.75 um !
