This study is well-organized and important for research community. This reviewer has two minor comments. 1）the authors should explain why only the data ended on 2018, but not 2022? 2) can urban atmospheric NH3 prevent the previously formed NH4NO3 from evaporating? The current discussion is imbalance.

Short summary

Ammonia (NH₃) is a key precursor for fine particulate matter (PM_2.5) and a primary form of reactive nitrogen, yet it has sparse ground measurements. We perform the first comprehensive comparison between ground observations and satellite retrievals in the US, demonstrating that satellite NH₃ data can help fill spatial gaps in the current ground monitoring networks. Trend analyses using both datasets highlight increasing NH₃ trends across the US, including the NH₃ hotspots and urban areas.
