  1. Lioliopoulos, P., Oikonomou, P., Boulougaris, G., Kolomvatsos, K.,, 'Real-Time Monitoring of Wildfire Pollutants for Health Impact Assessment', in IEEE International Geoscience and Remote Sensing Symposium (IGARSS),, July 7-12, Athens, Greece, 2024.
    Recognizing the severe health implications of dangerous pollutants emitted during a wildfire incident, we introduce a robust monitoring framework based on the Internet of Things (IoT) paradigm designed for real-time remote sensing of wildfire pollutants. The system is specifically adapted for measuring the wildfire health impact on firefighters and nearby residents. Its architecture comprises portable and stationary solutions and a Web application, enabling easy access to emission data and Air Quality Index (AQI) for interested parties and command \& control centers. The portable solution benefits firefighters by providing real-time air quality information, aiding in decision-making for safety and efficient firefighting, while the stationary one contributes to mitigating the risk of potential evacuation in a region near the fire incident. Interested parties e.g., local authorities, command centers and environmental monitoring agencies, can easily and seamlessly integrate our system into their operations by initiating simple requests in our REST API.
