Missour, nestled within the Fès-Meknès region of Morocco, occupies a geographically significant position at approximately 33.05°N, -3.98°W. The city’s terrain is characterized by gently rolling hills, part of the Middle Atlas mountains' foothills, contributing to a modest elevation averaging around 600 meters above sea level. This elevation, while not extreme, influences local air circulation patterns. Missour sits within a transitional zone, bordering both agricultural lands and increasingly, peri-urban development. The surrounding landscape is a mosaic of olive groves, cereal fields, and scattered woodlands, typical of the Moroccan interior. While not directly adjacent to a major river, the nearby Oued Er-Reham provides a limited source of moisture and influences microclimates. The urban–rural gradient around Missour is relatively gradual, with small villages and agricultural plots interspersed within the expanding urban footprint. This proximity to agricultural activity introduces potential sources of particulate matter, particularly during harvest seasons when burning of crop residues can occur. Further afield, the industrial belt surrounding Fès, a major economic hub, exerts an indirect influence, with potential for transported pollutants. The city’s location within a basin-like topography can exacerbate air quality issues, particularly during periods of temperature inversion, trapping pollutants close to the ground. The prevailing winds, generally from the northwest, play a crucial role in dispersing or concentrating pollutants, depending on their strength and direction.

Missour’s air quality experiences a distinct seasonal cycle dictated by its Mediterranean climate. The dry season, spanning roughly from April to October, typically sees the highest pollution concentrations. During these months, reduced rainfall and increased temperatures contribute to stagnant air conditions, particularly during the summer months (July-August). Temperature inversions, common in the autumn (September-October), trap pollutants near the ground, leading to periods of poor air quality. Agricultural practices, including the burning of crop residues after harvest, significantly contribute to particulate matter pollution during this period. The winter months (November-March) bring cooler temperatures and occasional rainfall, which helps to cleanse the atmosphere and reduce pollution levels. However, periods of fog, particularly in December and January, can trap pollutants, creating localized air quality concerns. Spring (March-April) marks a transition period, with increasing rainfall and wind speeds gradually improving air quality. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, particularly during periods of stagnant air or fog. Outdoor activities are generally more favorable during the wetter winter months and the transitional spring season. Avoiding strenuous activity during peak pollution episodes, especially in the late afternoon and early evening when temperatures are typically highest, is advisable. Maintaining awareness of local weather conditions and air quality forecasts is crucial for minimizing exposure.
