Abstract
The aerosol measurements have been carried out at Kolhapur (16°42′N, 74°14′E) by using twilight technique. Newly designed Semiautomatic Twilight Photometer was operated during the period 1 January 2009 to 30 December 2011 to study the vertical distribution of the mesospheric aerosol number density per cubic decimeter (dm3). Here after aerosol number density per cubic decimeter (dm3) is abbreviated as ‘AND’. In the present study vertical distribution of AND during strong meteor showers days is discussed. In the present work an attempt is made to calculate the mesospheric aerosol number density per cubic decimeter (AND) using Twilight Sounding Method (TSM), for the first time in India. The dust particles during strong meteor showers intrude in the Earth’s atmosphere below 120 Km. The dust particles of strong meteor showers penetrate the lower atmosphere and also act as cloud condensation nuclei (CCN).
