- Abstract
- The atmospheric-electric processes can be understood only if it is assumed that the atmosphere is electrically conducting. The presence of aerosols in the air was found to be greatly affecting the air ion concentration. At rural station Ramanandnagar, there are numbers of sources for the production of air ions, at the same time there are limited sources for the production of aerosol in the atmosphere. Variations of air ions in atmospheric air have been investigated using Gerdien type air ion counter. This air ion counter indigenously designed and developed at the Indian Institute of Tropical Meteorology Pune and operated at rural site Ramanandnagar. During the morning period average positive air ions were 9x102 ions per cm3 in January 2012, they start decreasing and reaches to minimum (1.2 x102 ions per cm3) in April. Average negative air ions were 6x102 ions per cm3 in January during the morning period (06:00-08:00 hours). During evening period average positive air ions were 11x102 ions per cm3 in January 2012, starts decreasing and reaches to minimum (1.8 x102 ions per cm3) in April. Pollution index above 1.2 in January, May and August 2012 during evening period (18:00-20:00 hours), which is harmful to the human health.
