Motto: Unlocking the weather data
inside every telecommunication network

MISSION

Telecommunication links already sense rainfall. GMDI makes that data flow. Sustainably, globally, and for the benefit of all. We are establishing the systems, standards, and partnerships to make telecom microwave links a permanent part of the world’s weather observation infrastructure.
