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.
