In October of 2015 the EPA modified the National Ambient Air Quality Standard (NAAQS) for ozone. The old standard was 75 ppb (8 hour average). The new standard is now 70 ppb (8 hour average). Since the AQI values are based on the NAAQS, that means the AQI values are going to be a little higher this year even if the ozone values are identical to last year. Hence, we are going to have more days in the Moderate range in 2016, and possibly even more days in the Unhealthy for Sensitive Groups range.

I will update the forecast on Mondays or Fridays or when conditions warrant an immediate update. You may or may not have noticed, but one of the things that is unique and special about my ozone AQI forecast is that unlike almost everybody else, I let you see what the forecast was. That allows the user an opportunity to see how accurate my forecast is (or is not). That is a feature I wish the weather web sites and other AQI forecasters would add to their web pages.

For Western Nevada County only, check out Ozone Maps at http://www.sparetheair.com/

For both Eastern and Western Nevada County, check out PM2.5 data click here.
Be sure to set PM2.5 for the Parameter, and in Step 3 set the county to “Nevada”
