Impact of High Energy Cosmic Rays on Global Atmospheric Electrical Parameters over Different Orographically Important Places of India

Abstract

Global atmospheric electrical parameters such as atmospheric conductivity, air-earth current density, atmospheric electric field, and atmospheric potential have been calculated for eighty different orographically important places of India under the influence of cosmic ray modulation factor due to Forbush decrease assuming fair weather conditions. The results have been compared with the earlier work of Kumar et al. (1998) and show that the correlation between cosmic rays and global atmospheric electrical parameters near the earth surface depends upon the relative magnitudes of galactic cosmic ray particles.

Optical particle sensor based measurement and analysis of atmospheric aerosol number concentration of various sizes over a tropical region of Northern India

“…Observation period from April to July has been chosen for the present study because in this period both the premonsoon and monsoon activities occur. The aerosol number concentration has a diurnal variation 13 . Aerosols data have been recorded for four size ranges (0.3-0.5, 0.5-1.0, 1.0-2.0 and 2.0-5.0 μm).…”

“…The study on aerosol distribution can be done by using various techniques available [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] such as Cascade impactor 12 , Lidar 17 , Low-pressure impactor 19,25 , Laser scatterometer 13 and Optical counter 3,26 etc. In the present study, we have measured the aerosol number concentration with an optical counter.…”

Earth’s Atmospheric Electricity Parameter Response During Venus Transit

“…Different atmospheric electricity properties such as very low frequency (VLF) sferics, atmospheric potential gradient (PG), air-earth current, Schumann resonance (SR) are directly and indirectly connected with the influence of solar radiation along with the outcome of some geophysical events. The parameters showed fluctuations under different situations (Kumar and Singh 2013).…”
