Heterogeneous hydrolysis of N2
on the surface of particles is crucial for nitrogen cycle in the atmosphere. This reaction rate is determined by meteorological and particle properties. However, its parameterization in previous 3-D modelling studies did not comprehensively consider these parameters. We propose a parameterization to take these parameters into account, improve the nitrate prediction, and report the organic coating suppression on N2
reaction is not as important as expected in EU.
