Aircraft profiles show the eastern Amazon emitting more carbon than it absorbs
Gatti and colleagues publish results from repeated vertical aircraft profiles flown over four sites through the 2010s, finding the eastern and especially southeastern basin to be a net carbon source while the wetter northwest remains a sink. Unlike a drought-year measurement, this describes a change of state in one region rather than a temporary perturbation across all of it.
Observed — measured or witnessed, with the observation cited.

Amazonia as a carbon source linked to deforestation and climate change
Supports the finding, from repeated vertical aircraft profiles over four Amazonian sites during the 2010s, that the eastern and especially southeastern basin is a net carbon source while the northwest remains a sink. V55 verification basis: not retrieved in this session; flux magnitudes are deliberately not quoted.
