| Zusammenfassung |
| A challenge for the quantitative analysis of tropospheric nitrogen dioxide
(NO2) column data from satellite observations is posed partly by the
lack of satellite-independent observations for validation. 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%), 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%/−30% is a reasonable estimate, accounting for different
regions. |
