We performed such observations of the tropospheric NO₂ column using the ground-based Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) technique in the North China Plain (NCP) from 29 May to 29 June 2006. Comparisons between tropospheric NO₂ columns measured by MAX-DOAS and the Ozone Monitoring Instrument (OMI) onboard the Aura satellite indicate that OMI data (the standard product, version 3) over NCP may have a positive bias of 1.6×10¹⁵ molecules cm^−2 (20%), where the estimated random error in the OMI data is 0.6×10¹⁵ molecules cm^−2 or approximately 8%. Combining these results with literature validation results for the US, Europe, and Pacific Ocean suggests that a bias of +20%/–30% is a reasonable estimate, accounting for different regions. Considering the uncertainty estimated here will pave the way for quantitative studies using OMI NO₂ data, especially over NCP. Boersma, K. F., Eskes, H. J., and Brinksma, E.
