Rocklin Unified School District

The Placer County Air Pollution Control District recommends we use the Placer County Website to monitor the air quality as they are maintaining and verifying the accuracy of their sensors. 

During a fire it is important that we monitor the PM 2.5.   The public health officer has recommended school closure if this reading is 500 or greater. 
Here is the county website.  There are not monitors in Rocklin so we need to look at Roseville and Lincoln.
