Wildfires can affect air hundreds of miles away

Wildfires can cause temporary large increases in outdoor airborne particles, and substantial increases in gaseous air pollutants such as carbon monoxide, nitrogen dioxide, formaldehyde, and acetaldehyde.  Large wildfires can increase air pollution over thousands of square kilometers [or thousands of square miles].

CAB installs PM2.5 monitor

The Clean Air Board announced that it has installed a new air quality monitor in downtown Carlisle near the Square.  The PM2.5 sensor will report its readings 24 hours a day.  The real-time data can be viewed on the PurpleAir network.  The PurpleAir™ sensor is a device that uses two laser particle counters to capture and record data about microscopic particulate matter (PM2.5) suspended in the air.  The sensor uses WiFi connectivity to display real-time air quality readings on the PurpleAir™ Map, which is a  world-wide map of monitors where data can be shared with the public.

DEP Issues a Code Orange Air Quality Action Day Forecast for June 9, 2020

Harrisburg, PA – The Pennsylvania Department of Environmental Protection (DEP) and its regional air quality partnerships have forecast a Code Orange Air Quality Action Day for ozone on June 9, 2020, for southeastern and southcentral Pennsylvania (encompassing the counties of Bucks, Chester, Cumberland, Dauphin, Delaware, Lancaster, Lebanon, Montgomery, Philadelphia, and York).
Strong sunshine, temperatures close to 90 degrees Fahrenheit, and light south to southwest winds will act to bring ozone concentrations to code ORANGE levels Tuesday afternoon. Concentrations of ozone are expected to be lower on Wednesday with only partly sunny skies and the chance for shower and thunderstorm development.
On air quality action days, young children, the elderly, and those with respiratory problems, such as asthma, emphysema, and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities.  Read more

NASA Satellite Data Show 30 Percent Drop In Air Pollution Over Northeast U.S.

Over the past several weeks, NASA satellite measurements have revealed significant reductions in air pollution over the major metropolitan areas of the Northeast United States. Similar reductions have been observed in other regions of the world. These recent improvements in air quality have come at a high cost, as communities grapple with widespread lockdowns and shelter-in-place orders as a result of the spread of COVID-19. Read more …

DEP Issues a Code Orange Air Quality Action Day Forecast for Southcentral Counties for June 16-18, 2018

The Pennsylvania Department of Environmental Protection and its regional air quality partnerships have forecast a Code Orange Air Quality Action Day for ozone on June 16, 2018 for the Pittsburgh region (encompassing Allegheny, Armstrong, Beaver, Butler, Fayette, Indiana, Mercer, Washington, and Westmoreland counties). A Code Orange Air Quality Action Day for ozone is also forecast on June 17 and 18 for the Pittsburgh region, southcentral counties (Cumberland, Dauphin, Lancaster, Lebanon, and York counties) and the Lehigh Valley (Berks, Lehigh, and Northampton counties).

On air quality action days, young children, the elderly and those with respiratory problems, such as asthma, emphysema and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities.

The U.S. Environmental Protection Agency’s standardized air quality index uses colors to report daily air quality. Green signifies good; yellow means moderate; orange represents unhealthy pollution levels for sensitive people; and red warns of unhealthy pollution levels for all.

To help keep the air healthy, residents and business are encouraged to voluntarily restrict certain pollution-producing activities by:
•    Refueling cars and trucks after dusk
•    Setting air conditioner thermostats to a higher temperature
•    Carpooling or using public transportation; and
•    Combining errands to reduce trips.
