Short summary

Ammonia (NH₃) is the important alkaline gas and the key component of fine particulate matter. We used satellite-based observations to analyze the changes in hourly NH₃ concentrations and estimated surface NH₃ concentrations and NH₃ emissions in China. This study shows enormous potential for using satellite data to estimate surface NH₃ concentrations and NH₃ emissions and provides an important reference for understanding NH₃ variation in China.
