TAQMPM2.5\Automatic Monitoring
 

1.Manual monitoring and automatic monitoring are two different methods which can result in data inconsistency. The Manual monitoring method is current PM2.5 Air Quality Standard.
2.Referring to the method used by the U.S. EPA: "The linear relationship between manual monitoring and automatic monitoring can be established by statistical linear regression (FRM-like)." Thus using statistical linear regression to convert automatic monitoring PM2.5 measurements into FRM-like data came into effect May 2014, and was applied going back to January 2014.
