Special NSW Bush Fires announcement
Note that the NSW Environment agency only reports the PM2.5 level as a 24 hour average, which can make it really difficult to find out what the actual air quality is in real time. However, since visibility is also reported as a 1 hour average, and it is a much better metric for determining the real time quality of the air, the AQI calculation has been updated to take into account the visibility.| Visibility 월요일 9시에 업데이트 30  PM2.5 | 월요일 9시에 업데이트 96  |
For instance, the PM2.5 24 hour average can be Good in Sydney, but the Visibility could be well past Hazardous. In this case, it would take several hours for the PM2.5 24 hour average to report as hazardous because there could have been a fairly good air quality over the last 24 hours and only just recently has the wind started to blow the smoke towards Sydney.
