Short summary
Satellite-observed HCHO / NO2 ratios are usually used to infer the O3 formation sensitivity regime. However, it only provides the one ratio around overpass time per day. In order to better characterize the O3 formation during the daytime, we proposed to introduce the surface-observed hourly O3 concentration increment and HCHO / NO2 to correct the satellited-observed HCHO / NO2. Moreover, the temporal and spatial variations of HCHO VCDs and the influencing factors in Shanghai were investigated.
