The Amazon forest is the largest tropical forest and is undergoing rapid transformations because of climate change. The uptake of carbon is affected by increasing temperatures, elevated CO2 concentrations, but also by the more frequent occurrence of large-scale droughts. Earlier studies have highlighted differences across the spatially heterogeneous basin, but in situ measurements over this large area are sparse. Here we will combine data from multiple satellite instruments to unravel processes of carbon exchange across a range of time scales. This will deliver key constraints for improving climate model projections and contribute to capacity for monitoring reforestation and deforestation activities.
