Hato Corozal, nestled within the Meta Department of Colombia, occupies a geographically significant position in the Amazon River basin's periphery. Located at approximately 3.18° N, 73.75° W, the town’s terrain is predominantly flat, characteristic of the Llanos Orientales, a vast tropical grassland plain. Its elevation, relatively low at around 200 meters above sea level, contributes to a stable atmospheric layer, which can, under certain conditions, trap pollutants. The surrounding landscape is dominated by expansive pastures used for cattle ranching, a major economic driver in the region, and interspersed with patches of gallery forest along smaller tributaries of the Guaviare River, which flows nearby. This agricultural intensity contributes to localized emissions, particularly from livestock and agricultural machinery. Hato Corozal’s position on the edge of the Amazon biome means it experiences high humidity and significant rainfall, influencing the dispersion of airborne particles. The urban–rural gradient is gradual; the town blends seamlessly into the surrounding agricultural landscape, with limited industrial activity directly within Hato Corozal itself. However, larger industrial zones, often related to agricultural processing or resource extraction, are present in nearby regional hubs, potentially impacting air quality through long-range transport of pollutants. The flat topography and limited natural barriers mean that wind patterns, while generally consistent, can be influenced by regional weather systems, affecting pollutant dispersal and creating localized areas of higher concentration.

Hato Corozal’s tropical climate dictates a distinct wet and dry season pattern, profoundly influencing its air quality. The dry season, typically spanning from December to April, often sees a slight increase in particulate matter concentrations. Reduced rainfall means less atmospheric cleansing, and the persistent use of agricultural machinery for land preparation and harvesting contributes to elevated dust levels. Temperature inversions, common during the cooler nights of the dry season, can trap pollutants close to the ground, exacerbating localized air quality issues. Conversely, the wet season, from May to November, brings frequent rainfall and increased humidity, naturally scrubbing the atmosphere and generally improving air quality. However, periods of intense rainfall can also lead to soil erosion and the suspension of fine particles, temporarily degrading air quality. Fog, particularly during the transition months (April/May and October/November), can also trap pollutants, creating short-lived episodes of reduced visibility and potentially impacting respiratory health. During the dry season, sensitive groups like children, the elderly, and individuals with pre-existing respiratory conditions should limit prolonged outdoor activity, especially during the early morning hours when inversions are most likely. The wet season generally offers more favourable conditions for outdoor pursuits, though vigilance regarding potential dust events following heavy rainfall remains prudent. Maintaining good ventilation indoors and avoiding exposure to smoke from agricultural fires are crucial year-round preventative measures.
