| Zusammenfassung |
| Using the nadir-viewing Global Ozone Measuring Experiment (GOME) UV/VIS spectrometer on the
ERS-2 satellite, we investigate short term variations in the vertical magnesium column densities
in the atmosphere and any
connection to possible enhanced mass deposition during a meteor shower. Time-dependent
mass influx rates are derived for all the major meteor showers using published estimates of mass
density and temporal profiles
of meteor showers. An average daily sporadic background mass flux rate is also calculated and used
as a baseline against
which calculated shower mass flux rates are compared. These theoretical mass flux rates are then
compared with GOME derived metal vertical column densities of Mg and Mg+ from the years
1996–2001. There is no correlation between theoretical mass flux rates and changes in the Mg and Mg+
metal column densities. A possible explanation for the lack of a shower related increase in metal
concentrations may be differences in the mass regimes dominating the average background mass flux
and shower mass flux. |
