Evaluation of Different Types of Aerosols From Wildfires in South America Using Ground‐Based Observations, Reanalysis and CMIP6 Models

open access: yesInternational Journal of Climatology, Volume 45, Issue 16, 30 December 2025.
We evaluate MERRA‐2 and CAMS reanalysis products against AERONET observations and compare them with CMIP6 models. CAMS shows better performance in capturing fire‐derived aerosols (BC AOD and OC AOD), with peak values during the dry season (August–October). Both reanalyses capture spatiotemporal AOD variability, although systematic overestimation occurs
