Journal ArticleDOI
Measurements of the electrical properties of dust storms
TL;DR: In this paper, the atmospheric electric potential gradient at ground level, space charge and wind speed (both at 1.25 meters above the ground), atmospheric temperature and relative humidity, and size distribution of dust particles collected at ground-level are also given.
Journal ArticleDOI
The atmospheric global electric circuit : An overview
Devendraa Siingh,Devendraa Siingh,V. Gopalakrishnan,Roohie Singh,A. K. Kamra,Shubha Singh,Vimlesh Pant,R. K. Singh,Abhay Kumar Singh +8 more
TL;DR: In this article, the role of various generators of the currents flowing in the lower and upper atmosphere and supplying currents to the Global Electric Circuit (GEC) has been reviewed and some unsolved problems in this area are reported for future investigations.
Journal ArticleDOI
Radon and its short-lived progeny: variations near the ground
K. Nagaraja,B.S.N. Prasad,M.S. Madhava,M. S. Chandrashekara,L. Paramesh,J. Sannappa,S. D. Pawar,Palani Murugavel,A. K. Kamra +8 more
TL;DR: In this article, the concentrations of radon and its progeny were measured, along with meteorological parameters from December 1997 to December 2000 for a continental location, Pune (18°N,74°E), India.
Journal ArticleDOI
Observations of new particle formation at two distinct Indian subcontinental urban locations
Vijay P. Kanawade,Sachchida Nand Tripathi,Devendraa Siingh,Alok Sagar Gautam,Atul Srivastava,A. K. Kamra,Vijay K. Soni,Virendra Sethi +7 more
TL;DR: In this article, the authors present a systematic analysis for new particle formation (NPF) from two distinct urban locations in India during April-May of two consecutive years, and find that the presence of pre-existing large particles at Kanpur than at Pune suppressed formation rates and favored particle growth.
Journal ArticleDOI
Review of electromagnetic coupling between the Earth's atmosphere and the space environment
Devendraa Siingh,Reeti Singh,A. K. Kamra,Prem N. Gupta,Rajesh Singh,V. Gopalakrishnan,Abhay Kumar Singh +6 more
TL;DR: In this article, the authors review the electrical properties of the lower and upper atmosphere along with various possible sources of the electromagnetic energy near and far above the Earth's surface and discuss the transport of electromagnetic energy from the atmosphere to the ionosphere and then to the magnetosphere.
