| Abstract |
An analysis has been performed of the random errors involved in measurements of ozone, SO2, NO, and NOx made with the Radian-built air-monitoring trailers. Differences observed between 'known' test gas concentrations and the corresponding machine responses were used to quantify the error properties. Data obtained through quality-assurance audits, performed both by EPA and Radian, and through daily autocalibrations of the instrumentation were analyzed. |
