About us


…is to push environmental data into the mainstream of decision-making and to unlock unlimited clean air for cities, businesses and citizens. Hawa Dawa aims to make the invisible visible: we form the first link of a new digital knowledge network to steer and activate resilient and climate-neutral cities.

Our primary focus is to facilitate the use of meaningful environmental data in decision-making. We compile air quality data from all available sources, from satellites to ground-based public measurement stations to IoT sensors and correlate them with use case-specific data, e.g. traffic.  These insights are made available on intuitive dashboards, commented APIs and deep-dive analytic reports. Our data cover the full scope from historical to real-time to predictive data and simulations.

We deploy state-of-the-art sensor technology, IoT, AI, machine learning, and cloud services to deliver A-grade air quality data in high spatial and temporal resolution.

Our international team comprises engineers, software and data analysts, sensor, satellite and traffic modelling experts as well as business folk and is  committed to realising this vision. Together we are pushing the frontiers of machine learning and sensor technologies to produce innovative new data products and services for our customers.
