Studies on the shift in the frequency of the first Schumann resonance mode during a solar proton event
TL;DR: In this article, the variation of the first Schumann resonance (SR) frequency spectra observed from the recorded data over Kolkata (22.56°N, 88.5°E) during a solar proton event (SPE) on July 14, 2000 has been presented.
Journal ArticleDOI
Effects of a Solar Eclipse on the Propagation of VLF-LF Signals: Observations and Results
Barin Kumar De,Syam Sundar De,B. Bandyopadhyay,Pinaki Pal,Rousan Ali,Suman Paul,Prabir Kanta Goswami +6 more
TL;DR: The results from measurements of some of the fundamental parameters (amplitude of sferics and transmitted signal, conductivity of lower ionosphere) of the ionospheric responses to the 22 July 2009 solar eclipse (partial: 91.7%) are shown in this article.
Journal ArticleDOI
The Effects of Solar Eclipse of August 1, 2008 on Earth’s Atmospheric Parameters
Syam Sundar De,Barin Kumar De,B. Bandyopadhyay,Bimal Kumar Sarkar,Suman Paul,D. K. Haldar,S. Barui,Asim Datta,Syam Sundar Paul,Nikhilesh Paul +9 more
TL;DR: In this paper, the effects of the solar eclipse on Fair Weather Field (FWF) and VLF amplitude and phase were investigated at Kolkata (latitude: 22°34′N, longitude: 88°30′E).
Journal ArticleDOI
Effects on atmospherics at 6 kHz and 9 kHz recorded at Tripura during the India-Pakistan Border earthquake
Syam Sundar De,Barin Kumar De,B. Bandyopadhyay,Suman Paul,D. K. Haldar,Anil K. Bhowmick,S. Barui,Rousan Ali +7 more
TL;DR: In this article, the results of some analyses of electromagnetic emissions recorded by VLF receivers at 6 kHz and 9 kHz over Agartala, Tripura, the North-Eastern state of India (Lat. 34.53° N, Long. 73.58° E) at Kashmir under Pakistan have been presented.
Analyses of Schumann resonance spectra from Kolkata and their possible interpretations
TL;DR: In this article, the amplitude and frequency fluctuations along with some aspects of Schumann Resonance (SR) during the period are investigated and the variation of global thunderstorm activity as inferred from monthly intensity fluctuations of global SR signals over Kolkata and Modra (Latitude 48.61oN) is presented and the observed difference has been interpreted.
