Effect of Twilight Airglow on The Vertical Profiles of Aerosols

Dr. Pratibha B. Mane

Abstract :

Aerosol measurements have been carried out at Kolhapur (16°42′N, 74°14′E) by using newly designed Semiautomatic Twilight Photometer, which now yields a reasonable qualitative picture of the day–to–day variability of the vertical distribution of the aerosols from about 6 km to a maximum of 350 km. The basic principle of this technique is that, if more number of aerosols exists in the atmosphere then more scattering takes place. The main aim of this study is to demonstrate the measurement capabilities offered by semiautomatic twilight photometer and it is the first attempt in India made by the authors to study the twilight airglow emission lines by twilight sounding method (TSM).
