8/12/2014 How to see 3 days of air quality warning values

Did you know anyone can access the charts that show 3 days of air quality values from the state monitoring network?

Here's how:
1. View the Washington Department of Ecology's monitoring site map here:  https://fortress.wa.gov/ecy/enviwa/Default.htm
2. Click on the colored dot that represents the monitor you're interested in (grey dots indicate the data is not available).
3. You'll see an image like the one below.  Click on "View Site Information" at the bottom of the pop-up box.

4. Next you'll see a screen that includes an image that looks a bit like a speedometer, click on the speedometer.
5. You'll get another image of the speedometer but you're almost there, click one last time on the speedometer.
6. And you're there!  Now you have a view of 3 days worth of air quality monitoring values converted into the WAQA health warning scale.  
-Note that some monitoring sites in Washington have instruments that monitor ozone and/or PM10 pollution. For smoke we focus on PM2.5.  (Notice that "PM2.5" is indicated somewhere on the images beginning with the speedometers.)   
-Also, the most current values shown on the chart use a mathematical calculation to predict the WAQA value so these values may change a bit as actual monitoring data is collected.
