 <p>The AQHI accounts for the cumulative effect of pollutant mixing, instead of basing the air quality on the greatest pollutant concentration. The AQHI is assumed to be an hourly value, as the observed AQHI in the British Columbia interactive map reports the ‘last hour’ value <sup class="footnote-ref"><a href="#fn4" id="fnref4">[4]</a></sup>.</p>
 <p>Canada additionally has an Info-Smog program that provides air quality forecasting. Numerical models established by the Environment and Climate Change Canada are used to predict PM2.5 and O3 concentrations for the next several hours <sup class="footnote-ref"><a href="#fn5" id="fnref5">[5]</a></sup>. A calculation method based on the AQHI formula is used to forecast the AQHI, however it only accounts for predicted concentrations of PM2.5 and O3. The air quality forecast is reported in three categories: good, fair, and poor. Two forecasts are issued daily: at 5 a.m. EST the forecast for today, tonight, and tomorrow is issued, and at 4 p.m. EST, the forecast for tonight and tomorrow is issued <sup class="footnote-ref"><a href="#fn5" id="fnref5:1">[5:1]</a></sup>. Note that another government website states that the first AQHI forecast is issued at 6 a.m. and second at 5 p.m. local time <sup class="footnote-ref"><a href="#fn6" id="fnref6">[6]</a></sup>, however it is unclear which time is correct. Forecast amendments can be issued at any time if necessary to provide the most relevant information.</p>
