Monitor Method Code¶
A three digit code representing the measurement method of the operational monitor. A method code is only unique within a parameter (that is, method 111 for ozone is not the same as method 111 for benzene). For QA assessments, this is the method of the monitor being assessed.
The submitted Monitor Method Code must match the previously defined method for the monitor for that day in AQS.
Must be a valid Monitor Method for the parameter.
