Atmospheric electricity measurements made during the last decade at Poona using balloon-borne sondes are briefly reviewed. The vertical distribution of potential gradient in the free atmosphere follows theoretical values only during the monsoon months, when the air is comparatively free from dust. During the summer months, the potential gradient is constant above the exchange layer and this is associated with the presence of the deep, dense dust layer that lies over the region and extends to over 10 km. into the atmosphere. The increase with height of the potential gradient above the 10 km. level during winter is shown to be closely related to the presence of the subtropical jet stream, which presumably transports electric charges to the upper levels over Poona.

The paper describes a new radiosonde developed at Poona for high altitude balloon soundings and the results of the high level radiosonde ascents taken at Hyderabad as part of the Indo-US Balloon Flight Programme—1961. The temperature data obtained during the programme are presented and compared with the results of the sounding balloon ascents made over Poona and Hyderabad during 1928–35.
