Zusammenfassung |
The Total Carbon Column Observing Network (TCCON) produces precise measurements of the
column average 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 sufficient accuracy to compute total columns that can be used in combination with in
situ measurements. The TCCON must therefore be calibrated to World Meteorological
Organization (WMO) in situ trace gas measurement scales. We present a calibration of TCCON
data using WMO-scale instrumentation 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 column data within error. |
