Journal ArticleDOI
Modeling of very low frequency (VLF) radio wave signal profile due to solar flares using the GEANT4 Monte Carlo simulation coupled with ionospheric chemistry
Sourav Palit,Tamal Basak,Sushanta Kumar Mondal,Sabyasachi Pal,S. K. Chakrabarti,S. K. Chakrabarti +5 more
TL;DR: In this article, the authors reproduce the deviation in VLF signal strength during solar flares by numerical modeling using GEANT4 Monte Carlo simulation code to compute the rate of ionization due to a M-class flare and a Xclass flare.
Journal ArticleDOI
Effective recombination coefficient and solar zenith angle effects on low-latitude D-region ionosphere evaluated from VLF signal amplitude and its time delay during X-ray solar flares
TL;DR: In this article, the effect of solar X-ray radiation on the ionospheric D-region was investigated and the effective electron recombination coefficient (αeff) at solar flare peak region was calculated.
Journal ArticleDOI

Sonali Chakrabarti,Sonali Chakrabarti,Sushanta Kumar Mondal,Sudipta Sasmal,Samir Kumar Pal,Tamal Basak,S. K. Chakrabarti,Debashis Bhowmick,Suman Ray,Surya K. Maji,A. Nandi,Vipin K. Yadav,T. B. Kotoch,Balaram Khadka,Kinsuk Giri,Sudip K. Garain,Asit K. Choudhury,N. N. Partra,Naseer Iqbal +18 more
TL;DR: In this article, the amplitude variation of the diurnal signal at each of these receiving stations in winter and summer was compared and the results generally agree with the signal shapes obtained using the long wave propagation capability code based on mode propagation through the Earth-ionosphere cavity.
Effective recombination coefficient and solar zenith angle effects on low-latitude D-region ionosphere evaluated from VLF signal amplitude and its time delay during X-ray solar flares
TL;DR: In this paper, the effect of solar X-ray radiation on the ionospheric D-region was investigated and the effective electron recombination coefficient (αeff) at solar flare peak region was calculated.
Journal ArticleDOI
Theoretical study of lower ionospheric response to solar flares: sluggishness of D-region and peak time delay
TL;DR: In this paper, the authors used a model to find ion densities and resulting very low frequency (VLF) signal perturbations during some solar flares and found that the delay in the peak of the electron densities in the lower ionosphere varies from height to height.
