Abstract
The TCCON (Total Carbon Column Observing Network) FTIR network provides highly accurate observations of greenhouse gases column-averaged dry-air mole fractions. As an important component of TCCON quality assurance measures, sealed cells 5 filled with approx. 5mbar of HCl are used for instrumental line shape (ILS) monitoring at all TCCON sites. Here, we introduce a calibration procedure for the HCl cells which applies a refillable, pressure-monitored reference cell filled with C2H2. Using this method, we identify residual variations of HCl purity between the TCCON cells as a non-negligible disturbance.
