LSCE and UMSA are conducting a campaign to measure vertical profiles and total columns of CO2, CH4 and CO in Bolivia, with logistical support from IRD, and support from ESA, ICOS-France, OBS4CLIM. The measurements aimed in particular at validating space-based measurements of CO2, CH4 and CO.

European ICOS stations observed significant increases in CO concentrations. This was due to air masses overflying fires in Canada. Interestingly, CO2 shows a negative anomaly: air masses have also flew over areas active in photosynthetic Carbon uptake, offsetting the CO2 emissions caused by fires.
