Short summary
This study examines how ground-based instruments measure air pollution and how well these measurements match satellite observations over Southeast Asia. We compared two observing methods and found that one captures more detailed short-term changes, while the other provides more stable and representative results. Satellite data improved with newer technology but still showed differences. These findings help improve how scientists interpret satellite data for air quality and climate studies.
