Abstract

The data completeness requirements for the production of defensible annual averages of air quality parameters are discussed. Data quality objectives concerning time coverage and data capture specified by current legislation are critically examined and the improved, combined metric of data coverage is proposed. Best practice proposals to ensure the representativeness of air quality data across the calendar year are proffered. These are based on minimising the bias between the annual average calculated using the data acquired and the annual average which would have been calculated if data coverage had been 100 %. In all cases the optimum solution is for air quality network operators to aim for 100 % data coverage.
