Data sets

COS Atmospheric Greenhouse Gas Mole Fractions of CO2, CH4, CO, 14CO2 and Meteorological ObservationsSeptember 2015–April 2019 for 19 stations (49 vertical levels), final quality controlled Level 2 data (Version 1.0) ICOS ERIC–Carbon Portal

Short summary
Continuous measurements of greenhouse gases using high-precision spectrometers started in 2011 on a tall tower with three sampling inlets at 10 m, 50 m and 120 m above the ground at the OPE station, in the eastern part of France. The measurement strategy for carbon dioxide (CO2), methane (CH4) and carbon monoxide (CO) follows the ICOS recommendations. Over the 2011–2018 period, the CO2 and CH4 data show trends with annual growth rates of 2.4 ppm yr−1 and 8.8 ppb yr−1 at the 120 m level.
