Bom Sucesso, nestled in the heart of Minas Gerais, Brazil, occupies a geographically significant position within the Serra da Mantiqueira mountain range. Located at approximately -21.0328° latitude and -44.7578° longitude, the city sits at an elevation of around 880 meters (2887 feet) above sea level, contributing to a generally cooler climate compared to lower-lying regions of Brazil. The surrounding landscape is characterized by rolling hills, dense Atlantic Forest remnants, and small agricultural plots, creating a distinct urban–rural gradient. Bom Sucesso’s terrain is undulating, with several small streams and seasonal waterways carving through the landscape, though no major rivers directly traverse the city. Its regional position places it within a zone transitioning between the more densely populated industrial belt of the Southeast and the agricultural heartland of Minas Gerais. This proximity influences land use patterns, with a mix of small-scale farming (coffee, sugarcane, and livestock) and some light industrial activity present in and around the city. The Atlantic Forest, though fragmented, still exerts a considerable influence on local microclimates, providing some natural air filtration. However, agricultural practices, particularly burning during land clearing and sugarcane harvesting, can contribute to localized air pollution events. The city’s relatively isolated location, while offering scenic beauty, also means that air pollutants can sometimes become trapped due to the topography, especially during periods of atmospheric stability. The surrounding hills act as barriers, hindering the dispersion of emissions from both local sources and those carried in from regional industrial areas.

Bom Sucesso experiences a tropical savanna climate, characterized by distinct wet and dry seasons rather than the four traditional seasons. The dry season, typically spanning from April to September, often sees a noticeable increase in air quality concerns. During these months, lower rainfall and reduced vegetation cover lead to a higher prevalence of dust and particulate matter, particularly from agricultural activities like sugarcane harvesting, which frequently involves controlled burns. Temperature inversions are more common during the dry season, trapping pollutants closer to the ground, especially in the mornings. The wet season, from October to March, brings increased rainfall and higher humidity, naturally cleansing the air and dispersing pollutants. However, periods of intense rainfall can also lead to increased mold and fungal spore concentrations, impacting indoor air quality. Fog, while infrequent, can occur during cooler periods in the dry season, further exacerbating air stagnation and trapping pollutants. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry months, particularly during periods of agricultural burning. Limiting outdoor exertion during the early morning hours when inversions are most likely to occur is advisable. Maintaining indoor air quality through proper ventilation and air filtration can also provide relief. The transition periods between wet and dry seasons often present unpredictable air quality conditions, requiring vigilance and awareness of local weather patterns and agricultural practices.
