The estimated parameters are in agreement with the results reported by other workers. The dispersion analysis of the whistlers recorded at Srinagar is also used to deduce information about ducts and for the determination of maximum electron density at the height of ionosphere. The maximum electron density at the height of ionosphere obtained from whistler dispersion comes out to be higher than that of the background, which is in accordance with characteristics of whistler duct. The equalivent width of the whistler duct at the maximum height of its path is found to be close to the obtained value from satellite and ground based observations. The width of ducts estimated from the diffuseness of the whistler trace observed at Srinagar is found to lie in the range of about 50-150 km. << 收起
