Resumo
In 2024, Brazil experienced record-breaking wildfire activity, underscoring the escalating
influence of climate change. This study examines the long-range transport of wildfiregenerated
aerosol plumes to São Paulo, combining multi-platform observations to trace
their origin and properties. During August and September—a period marked by intense
fire outbreaks in Pará and Mato Grosso do Sul—lidar measurements performed at São
Paulo detected pronounced aerosol plumes. To investigate their source and characteristics,
we integrated data from the Earth Cloud Aerosol and Radiation Explorer (EarthCARE)
satellite, HYSPLIT back-trajectory modeling, and ground-based AERONET and Raman
lidar measurements. Aerosol properties were derived from aerosol optical depth (AOD),
Ångström exponent, and lidar ratio (LR) retrievals. Back-trajectory analysis identified three
transport pathways originating from active fire zones, with coinciding AOD values (0.7–1.1)
and elevated LR (60–100 sr), indicative of dense smoke plumes. Compositional analysis
revealed a significant black carbon component, implicating wildfires near Corumbá (Mato
Grosso do Sul) and São Félix do Xingu (Pará) as probable emission sources. These findings
highlight the efficacy of satellite-based lidar systems, such as Atmospheric Lidar (ATLID)
onboard EarthCARE, in atmospheric monitoring, particularly in data-sparse regions where
ground instrumentation is limited.
