Bringing Data, Science, and Technology Together


We bring people together with high-quality information and tools that everyone can access and rely on to help answer their air quality questions. The Shair model is rooted in the peer-reviewed science and regulatory air quality models, using modern implementation to bring it to 10-meter resolution at street-level and in real time.
Our technology automates and streamlines the science and workflows that model the air, and we visualize the resulting data in two vibrant web-based mapping and analysis tools built specifically for various stakeholder types. We also provide an API that allows for data plug-in to any existing workflow or data management system.

Shair tech

Shair Tech is the contextual layer to the Shair Map, to support decision-makers as they develop pollution strategies. By going into the map to answer why the air quality is what it is with features like historical data averaging, comparison mode, and source apportionment, decision-makers are able to see patterns and identify pollution-mitigation strategies with the greatest impact.

Shair Tech gets communities on the path to doing something about the air by giving them data and a visual layer that enables identification of strategy.

Shair map

Shair Map is the primary visual layer of the model. With 10-meter resolution, the community is able to see pollutant concentrations on a block-to-block basis – visualizing the air where they live, work, and learn. With real-time updates, historical and forecast data, community members can make better decisions all the time to protect their health, and advocate for change. This Map empowers communities to understand the environment around them.

The Science

At Shair, we prioritize data quality by using validated scientific models to build our air quality tools. We make this science real-time and visualize it in an easy-to-understand map, creating a new role for regulatory science in community air quality strategies.

Under Shair’s visual layers, our model combines the peer-reviewed regional photochemical model, CAMx, with a highly efficient street-level dispersion model, Shairstreet, that enables an unprecedented 10-meter resolution while conserving mass when fusing the two models together. We combine static data sets like emissions inventories with real-time weather forecasts (computed with the WRF model) and traffic data. After the models automatically run every hour, the Shairsense layer incorporates real-time measurement data from air quality monitoring stations and sensors.

The Technology

As scientists, we wanted to strengthen our science and make it more accessible. Local-scale modelling, at ever-increasing model resolution, can strain computational, data, and analytical resources in traditional computing environments.

Powering our model with on-demand cloud computing, geospatial-aware databases, the novel fusion of regional air quality and street-level models, and contemporary web-based mapping and analytics tools can help enable a modern decision support system – with the ability to be efficient, accessible, real-time, flexible to use and remotely available. As a cloud-native platform, we have built in the benefits of the flexible technology into our science by containerizing complex scientific models into automated workflows that streamline the modelling process in a cost-effective manner. Our automated workflows enable hourly updates that run continuously without intervention and lend themselves to scientific research through modular, easy-to-read steps.
