a Map of the study area which includes residential postal codes (purple dots) within the Local Health Authority (LHA) boundaries (polygons) that intersect with the mainland southwestern region of the BC Heat Alert and Response System58,60. The map lines delineate study areas and do not necessarily depict accepted national boundaries. b Time series plots of average calendar week PM2.5 concentrations for the study area stratified by year, with the overall daily mean PM2.5 and average WFS day threshold indicated with the horizontal blue and red lines, respectively. c Time series plots of average weekly temperature for the study area stratified by year, with the overall daily mean temperature and average EHE day threshold indicated with the horizontal green and dark red lines, respectively.
