Short summary

Atmospheric NH₃ plays an important role in forming secondary aerosols and has a direct impact on sensitive ecosystems. This study aims to study its long-term variation and find that the long-term trend can be affected by climate change as well as other anthropogenic factors, depending on sites. A large percentage increase of atmospheric NH₃ at remote American sites is surprising and may cause a potential threat to sensitive ecosystems in the future.
