Licey al Medio, nestled within the Cibao Norte province of the Dominican Republic, occupies a strategically important position within the island’s fertile agricultural heartland. Located at approximately 19.43°N, 70.62°W, the city’s geography is characterized by gently rolling hills and plains, typical of the Cibao Valley. This valley, a significant portion of the Dominican Republic’s breadbasket, is bordered by the Cordillera Central mountain range to the north and the Sierra de Neiba to the south, influencing regional weather patterns and air circulation. Licey al Medio sits at a relatively low elevation, around 150 meters above sea level, contributing to a warmer climate and potentially trapping pollutants closer to the ground. The Ozama River, a major waterway, flows nearby, providing irrigation for the extensive agricultural activities – primarily sugarcane and livestock farming – that define the surrounding landscape. The urban–rural gradient transitions rapidly from the city’s core to intensive agricultural fields, with smaller rural settlements scattered throughout the valley. While Licey al Medio isn't directly adjacent to a major industrial belt, its proximity to Santiago, a significant industrial and commercial hub, means it can be affected by transboundary pollution. The prevailing easterly trade winds, common to the Caribbean, play a crucial role in dispersing or concentrating pollutants, depending on their strength and direction relative to the city’s topography. The surrounding landscape, dominated by agricultural fields and scattered vegetation, contributes to both natural sources of air pollutants (e.g., dust from tilling) and potential sinks (e.g., vegetation absorbing CO2).

The Dominican Republic’s tropical climate dictates Licey al Medio’s air quality patterns, exhibiting a distinct wet and dry season rather than the four traditional seasons. The dry season, typically spanning December to April, often sees a slight increase in particulate matter concentrations. This is due to reduced rainfall, which limits the natural cleansing effect of precipitation, and increased agricultural activity, including sugarcane burning, a common practice for land clearing and preparation. The drier air also promotes the formation of temperature inversions, particularly during calmer periods, trapping pollutants near the ground. During these inversions, pollutants released from agricultural practices and occasional vehicle emissions can accumulate, impacting local air quality. The wet season, from May to November, brings frequent rainfall and higher humidity. This increased precipitation effectively ‘washes’ the atmosphere, removing particulate matter and reducing overall pollution levels. However, heavy rainfall can also lead to increased soil erosion and dust storms, temporarily elevating particulate concentrations. Wind patterns are crucial; consistent easterly trade winds generally disperse pollutants, but periods of calm can lead to localized build-up. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should be particularly cautious during the dry season, especially during periods of agricultural burning or when temperature inversions are present. Limiting outdoor exertion during these times and ensuring adequate ventilation indoors is advisable. The transition months (April/May and November/December) often experience variable conditions, requiring vigilance and awareness of local air quality conditions.
