	<abstract content_type="html">A challenge for the quantitative analysis of tropospheric nitrogen dioxide
(NO&lt;sub&gt;2&lt;/sub&gt;) column data from satellite observations is posed partly by the
lack of satellite-independent observations for validation. We performed such
observations of the tropospheric NO&lt;sub&gt;2&lt;/sub&gt; 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 NO&lt;sub&gt;2&lt;/sub&gt; 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&amp;times;10&lt;sup&gt;15&lt;/sup&gt; molecules cm&lt;sup&gt;&amp;minus;2&lt;/sup&gt; (20%), yet within the
uncertainty of the OMI data. Combining these results with literature
validation results for the US, Europe, and Pacific Ocean suggests that a
bias of +20%/&amp;minus;30% is a reasonable estimate, accounting for different
regions.</abstract>
