Carlet, nestled in the heart of Valencia, Spain, occupies a geographically significant position within the Camp de Carlet comarca, a region characterized by a gently undulating plain. Located approximately 45 kilometers west of Valencia city, its coordinates (39.2264, -0.5211) place it within a landscape historically shaped by agricultural practices and, increasingly, urban expansion. The terrain is predominantly flat, averaging around 80 meters above sea level, which unfortunately limits natural air dispersion, particularly during periods of atmospheric stability. The surrounding landscape is a mosaic of cultivated fields – primarily rice paddies and citrus groves – interspersed with pockets of Mediterranean scrubland. This agricultural intensity contributes to localized emissions, particularly from agricultural machinery and fertilizer use. To the east, the sprawling urban area of Valencia exerts a considerable influence, with potential for transboundary pollution transport. The Turia River, though not directly adjacent to Carlet, flows nearby, influencing local humidity and potentially affecting the behaviour of pollutants. The urban–rural gradient is relatively gradual, with smaller villages and agricultural holdings surrounding Carlet, creating a continuous, albeit evolving, landscape. The absence of significant elevation changes and the proximity to both agricultural zones and the larger urban centre of Valencia combine to create a setting where air quality is susceptible to both local and regional influences, demanding careful monitoring and mitigation strategies. The relatively flat topography can exacerbate the effects of temperature inversions, trapping pollutants close to the ground.

Carlet’s air quality experiences a distinct seasonal rhythm dictated by Valencia’s Mediterranean climate. Summers (July-August) are typically hot and dry, characterized by stagnant air masses and frequent temperature inversions, particularly during the evening and early morning hours. These inversions trap pollutants released from agricultural activities, vehicle emissions, and domestic heating, leading to a noticeable increase in particulate matter and ground-level ozone. Spring (April-May) and Autumn (September-October) generally offer improved air quality, with more frequent wind patterns aiding in pollutant dispersal. However, agricultural burning, a traditional practice in the region, can occasionally contribute to localized spikes in smoke and particulate matter during these transitional seasons. Winters (November-March) are comparatively wetter, with occasional rainfall helping to cleanse the atmosphere. Fog, common during these months, can also trap pollutants, creating localized pockets of poor air quality, especially in the mornings. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during summer evenings and mornings, limiting strenuous outdoor activity and monitoring local air quality reports. The agricultural cycle significantly impacts air quality; periods of planting and harvesting see increased activity and emissions. While rainfall generally improves conditions, prolonged dry spells can exacerbate the build-up of pollutants, making spring and autumn a time to be mindful of air quality forecasts and adjust outdoor plans accordingly. The combination of temperature, wind patterns, and agricultural practices creates a complex interplay influencing Carlet’s air quality throughout the year.
