Resumo
In August 2019, a series of wildfires erupted in Australia, later termed "Black Summer," rapidly spreading
across various states and consuming a total area of approximately 103,000 square kilometers. This
study employed the MSP-Lidar I, an advanced remote sensing system, to analyze aerosol disturbances
in the stratosphere above São Paulo, with a focus on altitudes ranging from 15-30 km during January
2020. Through lidar measurements at three different wavelengths, we successfully identified and
analyzed the vertical dispersion of aerosol plumes. By utilizing atmospheric modeling, HYSPLIT, the
study traced the path of these plumes across the Pacific Ocean to São Paulo. The analysis revealed
three distinct plumes at specific altitudes, all originating from the regions affected by the Australian
wildfires. This research underscores the effectiveness of the MSP-Lidar I in tracking complex
atmospheric phenomena and significantly enhances our understanding of the long-term dynamics of
aerosol dispersion. These findings are crucial for air quality and global climate change studies, as they
underscore the far-reaching transcontinental impacts of large-scale wildfires. The study highlights
the urgent need for international collaboration in monitoring and mitigating the effects of such fires
on global atmospheric conditions.
