Long-term observations of tropospheric NO2, SO2 and HCHO by MAX-DOAS
in Yangtze River Delta area
Atmospheric pollution is an area of great concern in all densely populated areas around the world.
The concentration of pollutants can be measured with spectroscopy using differential optical absorption of scattered sunlight in the atmosphere. Researchers from China use this technique (multi-axis differential optical absorption spectroscopy) to monitor and characterize the concentration of several molecule species.
