Carbon monoxide (CO) and ethane (C 2 H 6 ) trends from ground-based solar FTIR measurements at six European stations, comparison and sensitivity analysis with the EMEP model
Trends in the CO andC 2 H 6 partial columns ~0–15 km) have been estimated from four European ground-based solar FTIR (Fourier Transform InfraRed) stations for the 1996–2006 time period. The CO trends from the four stations Jungfraujoch, Zugspitze, Harestua and Kiruna have been estimated to −0.45 ± 0...
