The India Meteorological Department (IMD) has been launching hydrogen-filled weather balloons with radiosondes from its Thiruvananthapuram centre twice daily since 1956. According to Neetha K. Gopal, Director of IMD, Thiruvananthapuram, one of the most accurate methods for studying the atmosphere is the use of a radiosonde attached to a weather balloons. Attached to weather balloons, the instruments collect data on temperature, humidity and wind conditions at different altitudes, enabling meteorologists to create a vertical profile of the atmosphere. Ms. Gopal said that though weather balloons may appear to be older technology, the instruments attached to them are modern and highly efficient. The software they use today has undergone significant technological improvements over …
