Atmospheric aerosols are minute particles (1 nm–100 μm) suspended in various layers of the Earth's atmosphere. During meteor showers, huge amount of cosmic debris called meteoroids enters into the Earth's atmosphere. These particles contribute to aerosols in the mesosphere and lower thermosphere. The aerosols emerged from meteor dust particles are having different size. The displacement of the particles through the atmosphere is directly proportional to their size. Therefore, we observed several maxima on the post-shower aerosol vertical profiles. One attempt is made to study correlation between the mesospheric and lower thermospheric Aerosol Number Density per cm3 (AND) and different types of Meteor Showers i.e. strong, medium-level and weak. Another attempt is made to trace the journey of meteor matter through lower atmospheric layers. The changes in AND are studied under this topic by using the data collected during January 2009 at Kolhapur (16°39′42.2″N, 74°14′20.8″E) by using Semiautomatic Twilight Photometer. This instrument provides the qualitative picture of vertical distribution of atmospheric aerosols from about 6 km to 360 km with the height resolution of 30 m at tropospheric levels.
