Spare The Air Day Notifications: All subscribers will receive Spare the Air Day advisories, which are issued for ground-level ozone when the Regional Air Quality Index (AQI) is expected to reach 150 (Unhealthy for Sensitive Groups).
'Don’t Light Tonight' Advisories: Voluntary Program to Reduce Pollution from Woodsmoke: All subscribers will receive notification of a 'Don’t Light Tonight' when particulate pollution (PM 2.5) in the District is expected to reach 25 micrograms per cubic meter of air or 78 AQI or higher. Burning wood or any solid fuel will be discouraged unless it is the sole source of heat. The advisory is in effect from midnight to midnight. For more information visit: http://www.ysaqmd.org/burn-DLT.php
Health Advisory: All subscribers will receive a Health Advisory, which is issued when air pollution is expected to quickly increase and reach the Very Unhealthy category on the AQI. This type of advisory is urgent and will remain in effect as long as the situation requires.
Air Quality Forecasts: By selecting the AQI level you wish to receive notification, you can determine the frequency of air quality forecasts. For those who are unusually sensitive to air pollution, a lower trigger is recommended.
The service is free of charge, and you are only required to provide your email address, pager or cell phone number and your zip code. This information will not be shared with any other organization, and we will only use it to transmit the EnviroFlash notifications. You can change your preferences at any time.
Meteorologists develop AQI forecasts using actual air quality data along with weather forecast information. These forecasts are then translated into a simple color-coded key (the Air Quality Index or AQI) that illustrates how healthy or unhealthy the air is. (See “About Air Quality Index” on left side box.)
With EnviroFlash, you will receive advance notice so that you can take action to reduce pollution. If you have questions, call (530) 757-3650 or toll free (800) 268-3650 within (707), (530) or (916) area codes or email email@example.com.
