OFRAC(12) real array Data for Secondary Organic Aerosol (SOA) (Used
only if MCHEM = 4 or 7). For MCHEM = 4 SOA
uses monthly organic fraction of fine particulate
for Clean Continental (default)
for Clean Marine (surface) (2*0.25, 9*30, 0.25)
2*0.15, 9*0.20,
0.15
for Urban – low biogenic (2*0.2,6*0.25,4*0.20)
for Urban – high biogenic (2*0.25,3*0.3,3*0.55,3*0.35,

Regional Plume – (2*0.2,1*0.25,1*0.35,1*0.25, 3*0.4,3*0.3,
