The Characterization of Haze and Dust Processes Using MAX-DOAS in Beijing, China [PDF]
Remote Sensing, 2021 Haze and dust pollution have a significant impact on human production, life, and health. In order to understand the pollution process, the study of these two pollution characteristics is important. In this study, a one-year observation was carried out at the Beijing Southern Suburb Observatory using the MAX-DOAS instrument, and the pollution ...

MAX-DOAS measurements of formaldehyde in the Po-Valley [PDF]
Atmospheric Chemistry and Physics, 2004 Abstract. During the first measurement campaign of the EU FORMAT project in summer 2002 near Milan, northern Italy, ground-based scattered light differential optical absorption spectroscopy (DOAS) measurements were performed using a new multi-axis instrument. From the data set of this four week measurement period, the detailed analysis results of three
