GPAZ Yorkton Station Data April 1 2019 to July 1 2019

NOTE FOR DATA FROM JAN 1, 2019 TO MAY 20, 2020: Ozone measurements from the GPAZ stations were compared to the National Air Pollution Surveillance (NAPS) station located in Regina. The general observation was that the average ozone measurements at the three GPAZ stations dropped below the measurements at the NAPS station at approximately the same time that the daily span values began to decrease. Based upon these observations, it is expected that degrading ozone scrubbers in each of the instruments resulted in measurements that were biased low. It was determined that a correction factor should be applied to the recorded data in order to most accurately reflect actual ozone concentrations at each of the sites for a period of time prior to the ozone scrubbers being replaced. The corrections were based on daily instrument zeros and spans over the same time period. Historical data from April 1, 2019 to July 1, 2020 from the Yorkton station. Contains hourly measurements for O3, NO, NO2, NOX, SO2, H2S, CS, FPM, Wind speed, Wind direction, Temperature, BP, RH, and Rain.
