Abstract
The ionosphere is an expansive natural detector and it characteristically reacts to ionizing influences coming from sun and other extraterrestrial energetic sources. In this article, first we give a brief review of earlier works performed specifically on Very Low Frequency (VLF) radio signal interaction with D-region ionosphere. Those are mainly related to the D-region ‘response time delay’ as experienced by VLF signal (△ t), effective recombination coefficient (α eff) and its connection with the D-region electron density (N e) and other essential parameters during X-ray solar flares. Further, we present the measurement techniques and the observed results regarding the same time delay (△ t) experienced by VLF signal with respect to the X-ray flux variation of solar flares. Several research groups have developed many lower ionospheric models based on theoretical and experimental results to deal with those above mentioned quantities. We follow a rather simplified model proposed by J. Wait for D-region through the Long Wave Propagation Capability (LWPC) numerical code to estimate the N e using flare induced amplitude-perturbation (△ A). Now, we use this △ t and N e-profile for estimation of the effective recombination coefficient (α eff). Lastly, we analyse the results and conclude.
