This white paper focuses on leveraging National Research and Education Networks (NRENs) and collaborations with meteorological agencies to enhance weather monitoring in Africa. By integrating low-cost weather stations based on IoT technologies, particularly LoRaWAN, these partnerships offer affordable and sustainable solutions to improve access to weather data across the continent. NRENs' high-speed networking capabilities facilitate seamless data collection, sharing, and transmission, thereby significantly enhancing the accuracy of weather forecasts. Working with meteorological agencies, NRENs play a pivotal role in providing real-time weather data, aiding decision-making in critical sectors such as agriculture, transportation, and disaster management, and contributing to overall socioeconomic progress in Africa.
