Deployment of Upper Air Radio Sounding Equipment in Nepal

Project Overview (Brief)

This project focused on the deployment of Upper Air Radio Sounding Equipment to enhance Nepal’s weather forecasting accuracy. Implemented by Mahavir Shree International Pvt. Ltd. in partnership with GRAW Radiosondes GmbH & Co. KG, the system was installed within Tribhuvan University, Kirtipur.

The project introduced Nepal’s first operational radiosonde setup, incorporating weather balloons, a hydrogen generator, and a ground station to collect upper atmospheric data. The goal was to strengthen the government's capacity to monitor weather patterns and climate variability with greater precision, supporting critical sectors such as agriculture, aviation, and disaster preparedness.

The Upper Air Radio Sounding System was successfully installed at Tribhuvan University, Kirtipur, with the goal of improving Nepal’s weather forecasting accuracy. This milestone project was implemented by Mahavir Shree International Pvt. Ltd., in collaboration with GRAW Radiosondes GmbH & Co. KG, and represents the first operational deployment of radiosonde technology in Nepal.

The system includes GRAW radiosondes, weather balloons, a Proton Onsite hydrogen generator, and a ground receiving station. Together, these components allow for real-time measurement of atmospheric parameters such as temperature, pressure, humidity, and wind direction at various altitudes.

To ensure long-term sustainability, the project team addressed technical challenges through hands-on training and international collaboration. The enhanced capabilities now empower the Department of Hydrology and Meteorology (DHM) to deliver more accurate and timely weather data.

By strengthening Nepal’s capacity for upper air monitoring, this project contributes to improved decision-making in key sectors such as agriculture, aviation, and disaster management.
