The tracer model employs simple decaying rates for most primary species, plus wet scavanging and dry
depostions et al. We can roughly derive the AVERAGE aging time for certain species based on their decaying
rates if rain and cloud are not heavy, or have few impacts on those species. The presented ages can
be used ONLY as a reference, due to realistic complexity. Please note that the tracer concentrations
DO NOT represent the realistic concentration, but only the conributions from various sources.
The model layer is defined in the WRF's half-sigma coordinate and driven by WRF 30km simulation. The
model height can be approximately treated as the altitude above
surface level where the topograph does not exceed 1km above sea level. The 50km Trans-Pacific tracer model
provides lateal and top boundary conditions for this forecast.
