[Update 11/18/2011: DEC has now updated its Air Quality Advisory to UNHEALTHY and extended it through Monday, Nov 21, 2011 at 5 pm. It was posted this afternoon: DEC Air Quality Advisory Valid 18 Nov to 21 Nov 2011.]
Today, Nov 18, 2011, PM 2.5 hourly readings climbed to over 100 micrograms/cubic meter in downtown Fairbanks and also in North Pole. The Borough took note of the rising PM 2.5 and declared air quality UNHEALTHY. The Fairbanks area is the only Alaskan community in PM 2.5 nonattainment. Online real-time monitoring is available from two monitors in downtown Fairbanks and one at North Pole Elementary.

The Alaska DEC again missed the boat. Despite the rising PM 2.5, DEC has not updated yesterday’s UNHEALTHY FOR SENSITIVE GROUPS advisory at the time of this post.
DEC staff in Anchorage monitor air quality here in Fairbanks. Today, Nov 18, 2011, all six Anchorage monitors were well below the state and federal 24-hour PM 2.5 standard of 35 µg/m3.
