ozone value造句

• The difference between the two sampled values determines the actual ozone value at that time.
• The "'Total Ozone Mapping Spectrometer "'( TOMS ) is a satellite instrument for measuring ozone values.
• The ozone AQI between 100 and 300 is computed by selecting the larger of the AQI calculated with a 1-hour ozone value and the AQI computed with the 8-hour ozone value.
• The ozone AQI between 100 and 300 is computed by selecting the larger of the AQI calculated with a 1-hour ozone value and the AQI computed with the 8-hour ozone value.
• During one cycle, the ozone monitor will take one air sample through the air inlet, and scrub the ozone from the air; for the next cycle, an air sample bypasses the scrubber and the ozone value calculated.
• Note : USEPA generally truncates ozone values to whole PPB, so a value of 13.78 PPB would use a value of 13.0 in the NowCast calculation, and a value of 0.01378 PPM would use a value 0.013 PPM . Using un-truncated numbers may yield discrepancies with forecast data presented at the AIRNow site.
