Creates compiled files of daily maximum hourly averages for select parameters (those with a 1-hour NAAQS defined - currently O₃, SO₂, and NO₂). Automatically examines the current year of data. Can be run for any year to update previous files. Will normally need to update previous year file when you are finished with all data validation activity for the fourth quarter of the previous year. Will also need to update whenever a change is made to historical data. Creates compiled files of thirty-minute averages for select parameters (those with a 30-minute standard defined - currently SO₂ and H₂S). Automatically examines the current year of data. Can be run for any year to update previous files. Will normally need to update previous year file when you are finished with all data validation activity for the fourth quarter of the previous year. Will also need to update whenever a change is made to historical data. The generation of alert emails for 30-minute exceedances is disabled for any year except for the current calendar year. Creates compiled files of 3-hour averages (daily max, all 3-hour averages) for select parameters (currently O₃). This was used for a 3-hour surrogate involving ozone. Automatically examines the current year of data. Can be run for any year to update previous files. Will normally need to update previous year file when you are finished with all data validation activity for the fourth quarter of the previous year. Will also need to update whenever a change is made to historical data. Creates compiled files of 8-hour averages (daily max, all 8-hour averages) for select parameters (those with an 8-hour NAAQS defined - currently O₃ and CO). Automatically examines the current year of data. Can be run for any year to update previous files. Will normally need to update previous year file when you are finished with all data validation activity for the fourth quarter of the previous year. Will also need to update whenever a change is made to historical data. Creates compiled files of daily block averages (midnight to midnight) for select parameters (those with an 24-hour NAAQS defined - currently PM-2.5, PM-10, SO₂, and O₃ which does not have a 24-hour NAAQS defined). Automatically examines the current year of data. Can be run for any year to update previous files. Will normally need to update previous year file when you are finished with all data validation activity for the fourth quarter of the previous year. Will also need to update whenever a change is made to historical data. Creates compiled files of rolling 24-hour averages for select parameters (currently PM-2.5 and PM-10). Automatically examines the current year of data. Can be run for any year to update previous files. Will normally need to update previous year file when you are finished with all data validation activity for the fourth quarter of the previous year. Will also need to update whenever a change is made to historical data. Creates three files for each year: Data Loss, High Values (if defined for any parameters), and Peak Values. The Data Loss file contains information from all sites and parameters for any hourly averages that are not flagged as ambient. The High Values file contains any parameters that exceed the high value threshold defined in the parameter definition. The Peak Values contains the maximum daily average for every parameter. Automatically examines the current year of data. Can be run for any year to update previous files. Will normally need to update previous year file when you are finished with all data validation activity for the fourth quarter of the previous year. Will also need to update whenever a change is made to historical data. Creates a file of any hourly ozone averages that exceed the 1-hour threshold which is currently tied to the 1-hour ozone NAAQS definition. Automatically examines the current year of data. Can be run for any year to update previous files. Will normally need to update previous year file when you are finished with all data validation activity for the fourth quarter of the previous year. Will also need to update whenever a change is made to historical data. Creates compiled files of daily block averages (midnight to midnight) for all AutoGC parameters. Automatically examines the current year of data. Can be run for any year to update previous files. Will normally need to update previous year file when you are finished with all data validation activity for the fourth quarter of the previous year. Will also need to update whenever a change is made to historical data. Creates the Discrete Data Loss file for each year. The Discrete Data Loss file contains information from all sites and parameters for any discrete measurements that are not flagged as ambient. Automatically examines the current year of data. Can be run for any year to update previous files. Will normally need to update previous year file when you are finished with all data validation activity for the fourth quarter of the previous year. Will also need to update whenever a change is made to historical data.
