Second Round Table on Advancing the Global Microwave Link Data Collection Initiative (GMDI)


The International Telecommunication Union (ITU), in collaboration with the COST Action OpenSense​, is pleased to announce the "Second Roundtable on the Global Microwave Link Data Collection Initiative (GMDI)". This event will take place on 21 May 2025, from 09:00 to 17:00 CET, at the ITU Headquarters in Geneva, Switzerland. Building on the success of the first roundtable held in September 2024, this meeting aims to review progress, refine strategies, and advance the initiative's goals for the global collection and utilization of commercial microwave link (CML) data in hydrometeorological applications.

CMLs have emerged as valuable tools for rainfall observation, particularly in data-scarce regions such as developing countries. However, the lack of standardized data collection and sharing mechanisms has limited their broader application. The GMDI seeks to address these challenges by fostering collaboration between stakeholders in telecommunications and hydrometeorology, including mobile network operators (MNOs), CML hardware vendors, national meteorological and hydrological services, researchers, and organizations such as ITU, EUMETNET, and the World Meteorological Organization (WMO).

The first roundtable identified four key focus areas for the initiative:
This second roundtable will evaluate progress in these areas, discuss challenges, and refine the roadmap for overcoming barriers to CML data exchange and its integration into meteorological observation systems.

Objective​
The primary objective of this roundtable is to advance the Global Microwave Link Data Collection Initiative by:​

About OpenSense (COST Action CA20136). OpenSense brings together scientists, weather service experts, and end-users to build a global community focused on opportunistic sensing technologies, including microwave links and citizen science. The initiative aims to overcome barriers to data exchange, define standards for large-scale benchmarking, and integrate opportunistic observations into traditional monitoring networks.
