Abstract:
At the Ny-Ålesund TCCON site, solar and lunar Fourier-Transform InfraRed (FTIR) absorption spectroscopy is performed to retrieve the column averaged dry-air mole fractions of various trace gases. In this data set, daily averages of the TCCON solar absorption measurements and nightly averages of lunar absorption measurements of xCO2 and xCH4 are provided. As an indication of the error of the measurement, the standard deviation of the daily mean and the number of contributing measurements are presented as well.
