Short summary
We used the MAX-DOAS instrument installed at the UCAS, Beijing, to evaluate effects on HCHO. The daily variation, transport, sources, and the effect of APEC emission control measures on HCHO were analyzed. Dependences of HCHO VCDs on wind fields indicated that the HCHO values were affected by the transport of pollutants from the south. The results from comparing the MAX-DOAS with the CAMS model indicate the CAMS model can simulate the effects of transport and the secondary sources of HCHO well.
