Union Minister of State (Independent Charge) Science & Technology; Minister of State (Independent Charge) Earth Sciences; MoS PMO, Personnel, Public Grievances, Pensions, Atomic Energy and Space, Dr Jitendra Singh today said, India Meteorological Department (IMD) is exploring the possibilities to deploy drones to gather atmospheric data from various locations, in place of weather balloons.

In a written reply in the Lok Sabha, Dr Jitendra Singh informed that an inter-departmental committee has been constituted by IMD to conduct studies in this regard. PM Narendra Modi Introduced Work Culture Where Public Welfare Schemes Reach All, Says Union Minister Jitendra Singh

In order to explore the technical feasibility of upper air boundary level data sensing, an invitation to industry and academia to demonstrate experimental drone-based radio-sounding on No Cost No Commitment (NCNC) basis has been released by Ministry of Earth Sciences (MoES) and it is available on MoES and IMD websites. The last date for the submission of proposal was 16th of July, 2022.

The Minister also informed that Ministry of Earth Sciences is setting up a Thunderstorm Testbed site over East India for in-depth study of thunderstorms over the region.

As a part of this project, the Ministry proposes to purchase two drones for monitoring of weather parameters of the atmospheric boundary layer prior to occurrence of thunderstorms and also for post event monitoring of damages.

Currently, radio sounding is the method in practice to measure vertical profile of physical properties of the upper air atmosphere and this is done by launching a transmitter interfaced with sensors aloft a weather balloon.

Although weather balloons are widespread in use since long, it poses a limitation to successful recovery of the sensor and also limits the use of more sophisticated and widespread sensors due to underlying implicit cost involved.

With the advent and sophistication in the unmanned aerial systems commonly known as drones, IMD is exploring the possibility to replace balloons with drones in gathering upper air observations. This new technology is expected to make the sensors recoverable and reusable thus likely to benefit IMD.

Upper air observations are a part of initial conditions for the weather forecast models. This new technology if found technically feasible through contemplated experimentation is expected to benefit IMD in the field of weather fo
