Sonosari, nestled within the Yogyakarta Special Region of Indonesia, occupies a geographically significant position at approximately -7.8014° latitude and 110.3644° longitude. The village sits within the Kedu Plain, a fertile lowland area characterized by gently rolling hills and volcanic soils, a legacy of the region's complex geological history. This plain is bordered to the north by the Menoreh Hills, a range of ancient volcanic formations that influence local weather patterns and airflow. Sonosari’s elevation, while relatively low, contributes to a localized basin effect, potentially trapping pollutants under certain meteorological conditions. The proximity to the Progo River, flowing eastward, provides a natural drainage pathway but can also contribute to humidity and fog formation, impacting air quality. The surrounding landscape is predominantly agricultural, with rice paddies and smaller farms dominating the rural areas. This agricultural activity, while vital to the local economy, can introduce particulate matter and ammonia into the atmosphere, particularly during planting and harvesting seasons. Sonosari’s urban-rural gradient is gradual; the village itself is a small settlement, transitioning seamlessly into the agricultural landscape. Further east, towards Yogyakarta city, the density increases, and industrial activity becomes more prevalent, potentially impacting Sonosari’s air quality through long-range transport of pollutants. The Menoreh Hills act as a partial barrier, moderating the direct impact of Yogyakarta’s industrial emissions, but prevailing winds can still carry pollutants into the area. The region’s volcanic activity, though currently dormant, has historically shaped the terrain and soil composition, influencing vegetation and, indirectly, air quality.

Sonosari’s tropical climate dictates a distinct wet and dry season, profoundly influencing its air quality profile. The dry season, typically spanning from April to October, is characterized by lower rainfall and increased sunshine hours. However, this period often sees a rise in particulate matter concentrations. Reduced rainfall means less atmospheric cleansing, and the drier conditions encourage agricultural burning, a common practice for land preparation, releasing significant amounts of smoke and particulate pollution. Temperature inversions, where cooler air becomes trapped beneath a layer of warmer air, are more frequent during the dry season, particularly in the evenings, further exacerbating the trapping of pollutants within the Kedu Plain. The wet season, from November to March, brings frequent rainfall and higher humidity, generally leading to improved air quality as pollutants are washed from the atmosphere. However, periods of prolonged fog, often associated with the wet season, can reduce visibility and trap pollutants close to the ground. During these foggy periods, even relatively low levels of pollution can pose a health risk. The monsoon winds, shifting direction seasonally, play a crucial role in dispersing or concentrating pollutants. Months like July and August, within the dry season, often experience the highest particulate matter levels. Conversely, December and January, during the peak of the wet season, typically offer the best air quality. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, particularly on days with agricultural burning or fog. Limiting outdoor exertion and wearing masks can help mitigate exposure.
