US space agency NASA has collaborated with Google to help local government monitor and predict the air quality. The duo will build advanced machine learning-based algorithms and link space data with Google Earth Engine data streams to generate high-resolution air quality maps in near real-time. Signed under the Space Act Agreement, Google and Nasa have committed to a 2 years Annex agreement under which they will leverage their expertise to help local governments make informed decisions about daily air quality monitoring and forecasts. The results will create city-scale, near real-time estimation and forecasting of harmful pollutants, such as nitrogen dioxide and fine particulate matter present in the atmosphere. Data will be collected from Google's Street View mapping vehicles, surface monitoring stations and other Earth monitoring satellites.
