Short summary
A new offline model (LSM_Nlateral_Off) was developed to simulate the lateral transfer of nitrogen from land to oceans through the river network, incorporating the decomposition of DON (dissolved organic N) and PON (particulate organic N) and denitrification of DIN (dissolved inorganic N) during fluvial transport. Evaluations using observational data indicate that the model reproduces observed rates and seasonal variations in water discharge and N flow well.
