Meteors are generally described as an atmospheric phenomenon caused by the entrance of particles from space (meteoroids or space debris) into Earth’s atmosphere. Meteors are classified according to their mass and size. Current day estimate for the global meteor flux which impact and disintegrate from earth’s atmosphere vary from 2000-200,000 tons per year. The meteoroid influx into the Earth’s atmosphere has been divided into two different phenomena, meteor showers and sporadic meteors. Only about one quarter of visually observable meteors are shower meteors while the rest consist of sporadic meteors, which are coming from all directions and not connected to any specific known shower. Over past three decades, a significant progress has been made in understanding sporadic meteors, meteor showers and their associated comets. Still, there are questions which remain unanswered regarding the origin and their effect in interplanetary medium also in earth’s atmosphere. For instance, does the meteor flux rate vary with altitude, latitude, seasonally and also globally? What are the typical lifetimes? What is the source of observed meteor rate? What effect do they have on the dynamics of earth’s ionosphere? In this talk, I will present our recent efforts and results on the questions raised above.
