Remote sensing of greenhouse gases with FTIR spectroscopy and estimate of their emissions

Abstract

A portable direct solar viewing Bruker EM27/SUN FTIR (Fourier Transform InfraRed) spectrometer has been installed in the urban city of Thessaloniki, Greece since January 2019, in the frame of the COllaborative Carbon Column Observing Network (COCCON), performing measurements of total column-averaged dry air mole fractions of greenhouse gases such as carbon dioxide (XCO2), methane (XCH4) and water vapor (XH2O) or carbon monoxide (XCO). Concerning the annual variability, the amplitude of the seasonal cycle in Thessaloniki’s CO2 concentrations follows the pattern of a typical mid-northern hemisphere COCCON site with a discernible seasonal variability and an interannual increase of about 2-3 ppm. XCO2 shows maximum concentrations with 424.94 ± 0.573 ppm, while a minimum is observed at 2019/07/22 with a value of 404.82 ± 0.602 ppm. XCO does not always show a pronounced annual cycle. XCO shows higher values during winter due to anthropogenic emissions (such as incomplete combustion of fossil ...
