Using the nadir-viewing Global Ozone Measuring Experiment (GOME) UV/VIS spectrometer on theERS-2 satellite, we investigate short term variations in the vertical magnesium column densitiesin the atmosphere and anyconnection to possible enhanced mass deposition during a meteor shower. Time-dependentmass influx rates are derived for all the major meteor showers using published estimates of massdensity and temporal profilesof meteor showers. An average daily sporadic background mass flux rate is also calculated and usedas a baseline againstwhich calculated shower mass flux rates are compared. These theoretical mass flux rates are thencompared with GOME derived metal vertical  column densities of Mg and Mg<sup>+</sup> from the years1996–2001. There is no correlation between theoretical mass flux rates and changes in the Mg and Mg<sup>+</sup>metal column densities. A possible explanation for the lack of a shower related increase in metalconcentrations may be differences in the mass regimes dominating the average background mass fluxand shower mass flux
