Short summary
Geostationary observations of NH3 provide an unprecedented opportunity to monitor spatial and temporal variations in emissions and their evolution throughout the day. Using 3 years of observations from FY-4B/GIIRS over East Asia, we demonstrated the enhanced capability of geostationary observations to identify emission sources and capture daytime variations associated with agricultural activities. This shows the potential of future geostationary satellites for monitoring air quality globally.
