Short summary
High daytime HONO mixing ratios in experiments suggest that an unknown daytime HONO source (P unknown) could exist. P unknown≈19.60×NO2×J(NO2) was obtained using observed data from 13 field experiments across the globe, then coupled into the WRF-Chem model. Simulations indicated that elevated P unknown was found in the coastal regions of China; the additional HONO sources, especially the P unknown produced significant increases of radicals in the major cities, and accelerated the radical cycles.
