• Spatial and seasonal variation of HCHO column can be use to constrain anthropogenic, biomass burning, and biogenic VOC emissions
• Previously unrecognized burning associated with winter wheat harvesting in June over North China Plains, equivalent to 30% to 70% percent of crop residual burned in field
