Monterrey, Casanare, Colombia, nestled at coordinates 4.8783, -72.8972, is a small city deeply embedded within the expansive Llanos Orientales (Eastern Plains) region. The terrain is primarily flat to gently undulating, characteristic of this vast grassland ecosystem. Situated at a relatively low elevation, approximately 100 meters above sea level, Monterrey’s air quality is significantly influenced by its open exposure and proximity to agricultural activities. The city’s population of 14,828 suggests a strong urban-rural gradient, with surrounding areas dedicated to cattle ranching and agriculture – primarily rice and palm oil cultivation. These agricultural practices contribute to particulate matter through land preparation, harvesting, and potential burning of residual biomass. The Casanare River flows nearby, but its influence on local air circulation is limited due to the prevailing wind patterns. Unlike cities hemmed in by mountains, Monterrey experiences less topographic trapping of pollutants. However, the lack of significant natural barriers means pollutants can be readily transported from, and to, surrounding areas. The regional climate, typical of the Llanos, is hot and humid, with distinct wet and dry seasons, impacting pollutant dispersion. The absence of major industrial belts within the immediate vicinity means agricultural sources are dominant, though long-range transport from larger urban centres is possible.
Monterrey’s air quality follows a strong seasonal pattern dictated by the region’s bimodal rainfall regime. The drier season, typically from December to March, sees a noticeable increase in particulate matter. Reduced rainfall means less atmospheric cleansing, and agricultural activities like land preparation and burning of crop residues are more frequent. Dust from unpaved roads also contributes. Temperature inversions, common during the cooler nights of the dry season, can trap pollutants near the ground, exacerbating conditions. The wet season, spanning roughly April to November, generally brings improved air quality. Frequent rainfall effectively washes pollutants from the atmosphere, and increased humidity promotes particle deposition. However, even during the wet season, localized pollution events can occur due to agricultural practices. August and September, often the wettest months, are generally the most favourable for outdoor activity. Sensitive groups – children, the elderly, and those with respiratory conditions – should be particularly cautious during the dry season, limiting strenuous outdoor exertion and monitoring their health. Avoiding peak agricultural activity periods is also advisable. Fog, though infrequent, can also contribute to pollutant build-up during cooler mornings.
