Effects of Temperature and Barometric Pressure on CO2 ...

Temperature and Barometric Pressure affect CO2 measurement individually as well as in combination. Table 4 shows the measured CO2 concentration for the range of Barometric Pressures recorded in DeSoto from 2005 to 2010 along with temperatures from 50 to 90°F. If the actual CO2 concentration was 1,000 ppm at 77°F and sea level, the measured ...
