Ammonia Cycling and Emerging Secondary Aerosols from Arable Agriculture: A European and Irish Perspective

Round 1

Reviewer 1 Report

This manuscript is well written and worthy of publication. This reviewer has two minor comments for the authors considering: 1) all modeling works on NH3 air/soil exchange don't include the effect of deposited NH3 on changing soil NH3 emission potentials；this would affect the model performance on NH3 mixing ratios; 2）Increased mixing ratios of atmospheric NH3 over the intensive agriculture zone sometimes play a role in suppressing evaporation of ammonium nitrate instead of its formation. In fact, high concentrations of ammonium nitrate can be rapidly formed in cooling combustion plumes within dozens of seconds and few minutes when they just leave the stack (Shen et al., 2022, Atmosphere, 13 (5), 673). At least to this reviewer, the highly concentrated ammonium nitrate would firstly experience evaporation process prior to its secondary ambient formation.

Round 2

Reviewer 2 Report

Although the authors did not make any effort to improve the manuscript, I have no objection for the manuscript to be published. 

Author Response

 A paragraph has been added from line 480 to include some review on thermodynamic models about NH3-ammonium nitrate partitioning.
