Abstract: The VLF spectral characteristics of the sferics over Kolkata (22.56°N, 88.5°E) are studied in relation to the rainy and winter seasons. The nature of sferics during rainy and winter seasons is determined for different times of the day. The recorded data of sferics from Kolkata exhibit many interesting monitoring possibilities due to the involvement of the characteristics of atmospheric and ionospheric parameters. The recorded sferics exhibit diurnal variation of electron density of the lower ionosphere. Many interesting features are observed including sunrise and sunset effects.
