Red de control de la calidad del aire CO-LOCATION FIELD STUDY

Test procedure kunak SENSING ANYWHERE ■ POST-PROCESSING: None. Real corrected data is calculated directly in the device without any delay. No re-calibrations or corrections are applied during the field tests unless specified. Then, the initial calibration is maintained during the whole field tests and results shown in this study. ■ SAMPLING PERIOD: data is averaged every hour to match data from reference station. ■ 100% of KUNAKAIR data is used for analysis, therefore, any possible outlier is included in the statistics. ■ VALIDATION: statistics are only calculated if valid Reference Data is available....

Analysis and Characterization Procedure ▪ ACCURACY: is obtained as the mean absolute error (MAE) between KUNAKAIR measurements and the reference instruments. 90% CONFIDENCE INTERVAL: the 90% of the measurements are below this error. Also, the relative error of the maximum error in the 90% of measurements is shown. RELATIVE EXPANDED UNCERTAINTY: DATA QUALITY OBJECTIVE (DQO): concentration value from which DQO defined in the EU Air Quality Directive (2008/50/EC) is met. Also, it is shown the DQ obtained for the Limit Values set in EU directive for indicative measurements. AVAILABILITY: is defined...
