Total averaged-dry air mole fractions of greenhouse gases for the region of Thessaloniki, such as carbon dioxide, methane, water vapor, carbon monoxide . Measurements were performed using a portable Bruker EM27/SUN spectrometer in the frame of the COllaborative Carbon Column Observing Network (COCCON), which measures direct solar radiation and each spectrum is obtained every 58 seconds, during clear-sky days. Data also include other measured quantities such as: the uncertainty of each measurement (rms), the time of measurement (UTC), the solar zenith ang...
