摘要: The contribution of the atmospheric deposition inorganic nitrogen compounds produced in East Asia to marine ecosystems North Western Pacific Ocean (NWPO) was investigated this study using a 3-D lower trophic-marine ecosystem model (NEMURO) combined with an regional chemical transport (WRF-CMAQ). monthly mean values for wet and dry compounds, including gases (HNO3 NH3) aerosol particles (NO3− NH4+), were determined WRF-CMAQ NWPO from 2009–2016. These input into NEMURO as additional source. indicated that annual average chlorophyll mass concentration at surface subtropical region (20°N–30°N; 125°E–150°E) increased 0.04 0.10 mg/m3. Similarly, gross primary productivity, integrated over sea depths 0–200 m, 85 147 mg C/m2/day because deposition. This indicates supply could have high nutrient impact on region.
