- Abstract
- The air ions are generated through thunder clouds, corona discharge, plant transpiration, combustion, waterfalls, wave breaking on water, splashing of raindrops and finally due to friction between two air levels and colliding of two air masses of different density and moisture. Seasonal variations of ions in atmospheric air have been investigated using Gerdien type air ion counter. This air ion counter is indigenously designed and developed at the Indian Institute of Tropical Meteorology Pune and operated at rural site Ramanandnagar. Positive and negative air ion concentration varies according to meteorological parameters temperature, relative humidity, and cloud cover. As average temperature increases from March to May relative humidity and cloud cover in the sky decreases, then both positive and negative ion concentration decreases from March to May and minimum-is observed in May. Meteorological parameters such as rain fall and wind speed also affects the concentration of positive and negative ions. Pollution index in January was 1.48, which is harmful to human health. Lowest value of pollution index is observed in October. Then as compared to all other months October is healthier to human health.
