Nagykáta, nestled in Pest County, Hungary, occupies a geographically significant position within the Budapest metropolitan area's periphery. Located approximately 30 kilometers east of the capital, its coordinates (47.4178, 19.7414) place it on a gently undulating plain, part of the Great Hungarian Plain, or Alföld. The terrain is predominantly agricultural, characterized by fertile loess soils ideal for crop cultivation, a defining feature of the surrounding landscape. This proximity to intensive agricultural practices, including livestock farming and the use of fertilizers, contributes to potential sources of ammonia and particulate matter. The town sits at a relatively low elevation, averaging around 110 meters above sea level, which can exacerbate the trapping of pollutants, particularly during periods of stable atmospheric conditions. While not directly adjacent to a major river, Nagykáta benefits from the drainage network of smaller streams flowing towards the Tisza River, influencing local humidity and potentially affecting pollutant dispersion. The urban–rural gradient is noticeable; Nagykáta retains a distinct village character, though it experiences increasing suburbanization due to its accessibility from Budapest. The eastern edge of the city borders agricultural fields, while to the west, residential areas gradually transition into more rural landscapes. The region's climate, a continental variety, with hot summers and cold winters, significantly impacts air quality dynamics, influencing temperature inversions and seasonal wind patterns. The presence of industrial zones further west, within the broader Pest County, introduces a regional pollution influence, occasionally impacting Nagykáta’s air quality.

Nagykáta’s air quality experiences a distinct seasonal cycle dictated by meteorological conditions and local activities. Spring (March-May) often sees elevated levels of pollen and dust, impacting respiratory health, particularly for allergy sufferers. Agricultural activities intensify during this period, releasing ammonia from fertilizers and contributing to particulate matter. Summer (June-August) typically brings drier conditions and higher temperatures, which can lead to photochemical smog formation, although the relatively low population density mitigates this somewhat. Stable atmospheric conditions, common in late summer, can trap pollutants near the ground. Autumn (September-November) marks a transition period. Harvest activities release dust and biomass burning can occur, contributing to particulate pollution. Temperature inversions, frequently occurring in October and November, trap cooler air near the ground, preventing the vertical dispersion of pollutants. Winter (December-February) often presents the most challenging air quality conditions. Cold temperatures and frequent fog events reduce atmospheric mixing, leading to pollutant accumulation. Residential heating, primarily using wood or coal in some households, adds to particulate matter and carbon monoxide levels. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should limit outdoor exertion during periods of fog and temperature inversions, particularly in the early morning hours. During the warmer months, outdoor activities are generally safer, but vigilance regarding pollen counts remains crucial. The prevailing winds, generally from the west, can carry pollutants from industrial areas, impacting air quality on certain days.
