Airvoice is developing a novel street-scale-resolution continuous air quality map

Creating a#nbsp;high-resolution heat map of#nbsp;air quality is#nbsp;another technological challenge for us#nbsp;to#nbsp;tackle. Airvoice’s mathematical modeling team is#nbsp;developing maps to#nbsp;provide air quality information for any location—at the moment and with a#nbsp;72-hour forecast.
Today, similar services already exist, but most of#nbsp;them provide unverified data. Such services are useful for obtaining an#nbsp;overview of#nbsp;the air quality in#nbsp;a#nbsp;city but are not suitable for making responsible decisions. City managers need reliable data. To#nbsp;get that reliable data, it#nbsp;is#nbsp;necessary to#nbsp;identify or#nbsp;deploy reliable real-time monitoring networks in#nbsp;the area of#nbsp;interest, adapt numerical models to#nbsp;local conditions, and conduct an#nbsp;inventory of#nbsp;emission sources (and then to#nbsp;keep it#nbsp;up-to-date combining automatic and manual updates).

Here’s how our model#nbsp;works.

Our fusion model combines a#nbsp;regional chemical transport model with a#nbsp;quasi-stationary building-height-aware Gaussian model. This predictive pollutant dispersion model is#nbsp;driven by#nbsp;either real-time traffic data or#nbsp;traffic forecasts provided by#nbsp;a#nbsp;powerful#nbsp;ML model; other pollution source data; the city’s built environment data; and more. Meteorological inputs are drawn from up-to-date regional weather forecasts produced by#nbsp;an#nbsp;expertly tuned WRF-ARW model.
