So, day 3 of the #HazardReductionBurn #smoke -- this is the situation here in The Gap this morning.

PM2.5 levels peaked at 224µg/m³ between 1-2AM, toughed at 115µg/m³, and are on the rise again. Presently it is at 167µg/m³ (8:22AM).

We need a little breeze to clear the air here.

By comparison, Upper Kedron (other side of Taylor Range) is reporting 65.7µg/m³.

A little wind is what we needed. 11:33AM things are looking much better. just 12µg/m³.
…and it's back. Creeping up over the last 30 minutes. Presently at 84µg/m³, with the density increasing by ~4-5µg/m³ each minute.

I've just thrown this little page together…

I'll probably get rid of it once the backburning is passed, but this is the raw data along with the current conditions. The current conditions update each minute (self-refreshing).

I might see if I can get a chart going on it, the data's there.

Data flow is from the data logger → #6LoWPAN mesh → #CoAP proxy → #WideSky back-end → #pyhaystack → JSON files to be served up by #OpenHTTPD

The pyhaystack script runs from `cron`.
