Comparing the Effects of Wildfire and Hazard Reduction Burning Area on Air Quality in Sydney
Abstract
:1. Introduction
- Is there a difference between the effect of HRB area and wildfire area on air pollution in Sydney, as measured by 24 h mean PM2.5?
- Does increasing HRB treatment increase or decrease overall (HRB + wildfire) PM levels in Sydney (the trade-off between HRB and wildfires)?
- What is driving the nature of the trade-off?
