Do you have to recertify data if it is null coded after you have certified the data?
If you replace a sample measurement number with a null code, then AQS will reset the certification flag to "M". Alternatively, if you have a date-time where there is no raw data value and submit a null code for that date-time then AQS should not change the flag.

What is the difference between Agency and Screening Group?
Historically, AQS used an abstraction called "Screening Groups" for security access control - i.e. who was allowed to modify data in AQS. Under this model, Monitors were owned by Screening Groups and users were assigned to screening groups based on which monitors they needed to access. This security model has…
