Marine

ModelingToolkit implementation of the Marine atmospheric aerosol size distribution, from Seinfeld & Pandis (2006), Atmospheric Chemistry and Physics, 2nd ed., Chapter 8 ("Properties of the Atmospheric Aerosol"), Table 8.3. The Marine distribution is a preset of the multi-modal lognormal AerosolDistribution model: three lognormal modes (N = [133, 66.6, 3.1] cm^-3, D_g = [0.008, 0.266, 0.580] um, log10 sigma = [0.657, 0.210, 0.396]) — a dilute marine boundary-layer background with a nucleation mode, an accumulation mode, and a coarse mode at 0.58 um. The model represents the aerosol number, surface-area and volume distributions as a sum of the three modes (Eq. 8.54) and reports the total number/surface/volume concentrations, the mode-1 Hatch-Choate diameters, and the vertical aerosol mass profile (Eq. 8.55). Migrated from Aerosol.jl MarineAerosol, a preset wrapper around AerosolDistribution(3). Purely algebraic: ten observed outputs, no differential states, an empty equations array. The upstream length-n_modes array parameters are scalarized at n_modes = 3 with the Marine Table 8.3 mode parameters as defaults.
