Abstract
A simple but innovated calibration procedure for the measurements of volatile organic compounds in the atmosphere is introduced via the use of CCl2FCCIF2 (CFC-113) long-term global data set as an illustration. Non-linear response for the electron capture detector toward CFC-113 was carefully calibrated within and beyond the measurement working range. Our measurement results, after correction for non-linearity, are in excellent agreement with those of the ALE/GAGE monitoring program, suggesting our calibration method along with its results are experimentally sound and well executed. Our global measurements show that, after years of rapid growth of CFC-113 in the atmosphere, its concentration had been leveling-off and even started to decline in 1995.
