总碳柱观测网络（TCCON）在全球多个站点对CO2、CO、CH4、N2O和H2O的柱平均干空气摩尔分数进行精确测量。这些观测依赖于光谱参数，这些光谱参数不具有足够的准确度来计算可以与原位测量组合使用的总柱。因此，TCCON必须根据世界气象组织（WMO）现场痕量气体测量标度进行校准。我们提出了一个校准的TCCON数据使用WMO规模的instrumentation飞机上，测量剖面超过四个TCCON站在2008年和2009年。这些校准与2004年和2006年的类似观测进行了比较。结果表明，每种气体的单个全局校准因子在误差范围内准确捕获TCCON总柱数据。
The Total Carbon Column Observing Network (TCCON) produces precise measurements of the column av- erage dry-air mole fractions of CO2, CO, CH4, N2O and H2O at a variety of sites worldwide. These observations rely on spectroscopic parameters that are not known with suffi- cient accuracy to compute total columns that can be used in combination with in situ measurements. The TCCON must therefore be calibrated to World Meteorological Orga- nization (WMO) in situ trace gas measurement scales. We present a calibration of TCCON data using WMO-scale in- strumentation aboard aircraft that measured profiles over four TCCON stations during 2008 and 2009. These calibrations are compared with similar observations made in 2004 and 2006. The results indicate that a single, global calibration factor for each gas accurately captures the TCCON total col- umn data within error.
