This post had been titled “Secondary North Pole Elementary PM 2.5 Monitor Reads True and HIGH.”
That is no longer correct.
UPDATE 2/14/2012: The more accurate North Pole secondary “PM2.5L 2” monitor stopped working Feb 1. North Pole is left with the primary “PM2.5L 1hr” monitor that reads low, perhaps by 50%. Nothing has come of talk of putting a monitor in the thickest of the smoke in North Pole’s Rectangle of Death at the Hurst Fire Station. To see hourly smoke levels, visit Fortress site from Real-time Monitoring.
UPDATE 1/14/2012 @ 7 pm: PM 2.5 has gotten much worse in North Pole tonight. At the Elementary School at 7 pm the 1-hour average showed 87.4 µg/m3 at the primary monitor and 170 µg/m3 at the secondary. At 4:30 pm, the Borough updated its Air Quality Advisory to UNHEALTHY for North Pole, using the secondary North Pole Elementary monitor. DEC has no advisory in effect.
The primary North Pole Elementary monitor (PM25L 1hr) has been erratic and underreports PM 2.5 concentrations.
Residents should watch the secondary North Pole Elementary monitor (PM25L_2) for PM 2.5 pollution in North Pole. The Borough is now displaying the secondary monitor in place of the primary North Pole Elementary on its easy-to-use FNSB Live Hourly PM 2.5 site.
