Short summary

We estimate 2019 Brazilian fire carbon monoxide (CO) emissions using CO retrievals from multiple satellites in a new top-down inversion framework. The retrievals strongly constrain fire emissions and complement existing inventories. National-scale posterior emissions align well with the new Global Fire Emissions Database v5.1, supporting progress in fire emission models. Yet, posterior emissions in the Cerrado and Caatinga are systematically higher than inventories; we discuss potential drivers.
