Alto Garças, nestled in the heart of Mato Grosso, Brazil, at coordinates -16.9439, -53.5278, presents a unique geographic context influencing its air quality. The city sits within the Cerrado biome, a vast tropical savanna ecoregion characterized by rolling hills, gallery forests along waterways, and a distinct dry season. Its elevation, approximately 360 meters above sea level, contributes to localized weather patterns. The Araguaia River lies relatively close, impacting humidity and potentially contributing to fog formation during cooler months. While not heavily industrialized, the surrounding region is dominated by extensive agricultural activity, primarily cattle ranching and soybean cultivation. This agricultural landscape is a significant factor; land clearing through burning, a common practice for pasture creation and crop residue management, is a major source of particulate matter. The urban-rural gradient is relatively sharp, with the city itself being a comparatively small settlement surrounded by large expanses of agricultural land and natural Cerrado vegetation. This proximity means that air quality within Alto Garças is heavily influenced by regional land use practices and meteorological conditions that transport pollutants from surrounding areas. The terrain, while generally undulating, doesn’t offer significant natural barriers to air flow, meaning pollutants can disperse, but also accumulate under certain conditions.
Alto Garças experiences a pronounced wet and dry season, dictating the annual air quality narrative. The dry season, typically from May to September, is when air quality deteriorates most significantly. This is directly linked to increased agricultural burning for land preparation and pasture renewal. Lower humidity and stable atmospheric conditions during these months trap pollutants near the ground, leading to higher concentrations of particulate matter (PM2.5 and PM10). October and November mark the transition, with sporadic rainfall offering temporary relief, but burning often continues. The wet season, from December to April, generally brings improved air quality. Frequent rainfall effectively washes pollutants from the atmosphere, and higher humidity reduces the likelihood of dust suspension. However, even during the wet season, localized burning can still occur, impacting air quality. Temperature inversions, common during cooler nights, can exacerbate pollution events regardless of the season. Sensitive groups – children, the elderly, and individuals with respiratory conditions – should be particularly cautious during the dry season, limiting strenuous outdoor activity and monitoring their health. Avoiding outdoor exertion during periods of visible smoke is crucial. The months of August and September are typically the most challenging for air quality, while December through February offer the most favourable conditions.
