The Visual Air Quality Issue

Scenic vistas are highly prized by residents and visitors

SLIDE 3

Visual air quality describes the effect of air pollution on the view. It is a key element of the Integrated Air Quality and Greenhouse Gas Management Plan. GOAL 2 – Improve visual air quality

Visual Air Quality Examples

09 Jun 2014 PM2.5 = 0.5 µg/m3 (24h = 2.1 µg/m3) 09 Aug 2014 PM2.5 = 6.1 µg/m3 (24h = 7.1 µg/m3) 11 Aug 2014 PM2.5 = 20.6 µg/m3 (24h = 15.2 µg/m3)
