Air Quality Hackathon is an event organized in collaboration with Amazon Web Services (AWS). It is aimed at finding innovative technical solutions for changemakers to solve the problem of air pollution – considered a "silent killer". Air pollution is one of the most pressing health and environmental issues and most acutely affects populations in South, Southeast Asia and Sub-Saharan Africa. Hackathon challenges are provided by the world's leading non-profits in these regions. Tech companies around the world will form teams to compete throughout this three-day online event to work on solving critical issues relating to air quality. Participants, with the help of technical mentors, will use the latest cloud technology and Artificial Intelligence (AI) tools to bridge the data, forecasting, monitoring and information gap and support communities with access to clean air.
