| Zusammenfassung |
| From Multi-Axis- (MAX-) DOAS observations, information on tropospheric trace
gases close to the surface and up to the free troposphere can be obtained.
Usually MAX-DOAS observations are performed at fixed locations, which allows
to retrieve the diurnal variation of tropospheric species at that location.
Alternatively, MAX-DOAS observations can also be made on mobile platforms
like cars, ships or aircrafts. Then, in addition to the vertical (and
temporal) distribution, also the horizontal variation of tropospheric trace
gases can be measured. Such information is important for the quantitative
comparison with model simulations, study of transport processes, and for the
validation of tropospheric trace gas products from satellite observations.
However, for MAX-DOAS observations from mobile platforms, the standard
analysis techniques for MAX-DOAS observations can usually not be applied,
because the probed airmasses can change rapidly between successive
measurements. In this study we introduce a new technique which overcomes
these problems and allows the exploitation of the full information content
of mobile MAX-DOAS observations. Our method can also be applied to MAX-DOAS
observations made at fixed locations in order to improve the accuracy
especially in cases of strong winds. We apply the new technique to MAX-DOAS
observations made during an automobile trip from Brussels to Heidelberg. |
