to compare against the 8H standard from regulator, How do i workout averaging for any particular date and fetch the 8 H average value and compare for the compliance/ exceedance...is it rolling average, if so how I calculate - need some literature for better understanding to confirm what I believe the way is....
Hey there Sivarajan Radhakrishnan! When it comes to ambient air quality monitoring for parameters like Ozone and CO, understanding the 8-hour averaging period is crucial. Basically, it means that the concentration of these pollutants is averaged over an 8-hour time frame to assess their levels accurately.
My monograph can be a good resource:

To calculate the 8-hour average for a particular date, you'll Sivarajan Radhakrishnan need to collect data points at regular intervals throughout the day and then average them over an 8-hour period. This could involve taking readings every hour and then averaging the values for the 8-hour window.
Now, as for comparing these averages against regulatory standards, it's indeed essential to ensure compliance and identify any exceedances. If there's a rolling average involved, it means continuously updating the average as new data points become available.

For a more comprehensive understanding and confirmation of your Sivarajan Radhakrishnan approach, seeking literature on air quality monitoring standards and methodologies would be beneficial. Look for resources that delve into the specifics of calculating and interpreting 8-hour averages for Ozone and CO levels. It'll provide the clarity and confidence you Sivarajan Radhakrishnan need in your Sivarajan Radhakrishnan monitoring process. Let me know if you Sivarajan Radhakrishnan need further assistance!
Take a step back. Air quality standards are based on health studies. Ozone health studies show that one-hour exposures at a specific level demonstrate health impacts. These studies show exposure to ozone levels for a longer timeframe at a lower level demonstrate health impacts. The longer the averaging the timeframe, the more stringent the standard. The law mandelates application of a margin of safety in the determination of the level of the standard. Lastly, the primary (health based) or secondary (non-health-based reasons) is a goal for standard attainment. Setting air quality standards is a long process, the law dictates a review of the air quality standards at regular intervals.
