New Delhi: India Drones are set to be deployed to collect atmospheric data that is currently collected by sending sensors via weather balloons released twice every day from at least 55 locations across the country.
Sensors mounted in the radiosonde, a telemetry instrument carried by a weather balloon, record atmospheric pressure, temperature, wind direction and speed as the hydrogen-filled weather balloon climbs to an altitude of 12 km and is transmitted via radio. Transmits data from ground to receiver. Signal.

However, weather balloons and radiosonde are inaccessible because they are carried away by weather stations that release them into the atmosphere. We are now exploring the possibility of using drones to collect this atmospheric data which is important for weather forecasting, M Ravichandran, Secretary, Ministry of Earth Sciences told PTI.
Various studies have suggested that specialized drones equipped with sensors to collect weather data could be an efficient successor to traditional weather balloons. The India Meteorological Department (IMD) collects weather data from 550 locations across the country through weather stations and uses radiosonde observations that are fed into forecast models to issue weather forecasts.
Drones have a significant advantage over weather balloons as they can be controlled and directed to fly at low as well as high altitudes. IMD plans to use drones to collect data up to an altitude of five km and compare it with the data collected using conventional weather balloons. It has invited industry and academia to join forces in demonstrating the potential of drone technology for weather observation.
The Met Office said it is expected that the drone should be capable, economically viable, easily deployable and recoverable and technically comparable to currently deployed radiosonde for upper air observations up to the boundary layer of the upper air atmosphere. Or should be better.

While weather balloon flights typically last two hours, the IMD expects to collect data using drones during the 40-minute flight.
If successful, a major advantage would be to reduce wastage of radioseconds as the IMD loses more than 100 such instruments every day because weather balloons cannot be retrieved after their flight.
