Folks,
I spent all of today in the Blue Mountains. Apart from the cloudy overcast and rain showers(yipee!) the air quality seemed moderately good in comparison to the last couple of weeks, according to my own onboard smoke particle detection system ie. no irritated eyes or nose, no coughing or wheezing. So, I am a little dubious about the smoke pollution detection system shown on the above site. For example the reading of 147 units near Katoomba HS is rated as "hazardous" yet in North Katoomba the reading is only 4 units which is supposedly OK. The two locations are only a couple of K's apart. No doubt there are extraneous factors at work eg local topography, local wind direction variation, exposure of the sensor. Just sayin'.Also, can anyone tell me if the BOM radar only shows rain or does it detecting dense smoke colums as well and showing it as rain?
