Introduction of Ground-based Remote Sensing and Applications for Air Quality Monitoring

Abstract

Ground-based remote sensing is widely used in various research fields related to the atmospheric environment study. With the increased operations of satellites and airborne observation in recent years, ground-based observation instruments have become more frequent, and their operation and applications have become more diverse. This paper provides an introduction to ground-based remote sensing instruments used in atmospheric environment research, especial to Dobson and Brewer spectrophotometers, MAX-DOAS instrument, AERONET Sunphotometer, Pandora spectrometer, and Lidar instrument. Also, this paper summarizes the key research areas adopted by the ground-based remote sensing dataset. Since the classical ground-based instruments such as the Brewer and Dobson spectrophotometers, a variety of instruments for observing aerosols and trace gases are now being operated both domestically and internationally. Through these instruments, it has been confirmed that ground-based remote sensing has been actively utilized for satellite/airborne data validation, atmospheric quality characteristics analysis, and long-term changes in air quality.
