Paragould, Arkansas, nestled in the northeastern corner of the state, occupies a geographically transitional position within the Mississippi Alluvial Plain and the foothills of the Ozark Mountains. The city’s coordinates (36.0555, -90.5149) place it within Greene County, a landscape characterized by gently rolling hills and fertile agricultural land. Elevation averages around 285 feet above sea level, contributing to relatively stable atmospheric conditions. The St. Francis River flows nearby, influencing local humidity and occasionally contributing to fog formation, which can trap pollutants. Paragould’s urban character is that of a regional hub for agriculture, with surrounding areas dominated by soybean, rice, and cotton farming. This agricultural activity introduces potential sources of particulate matter, including dust from fields and emissions from farm machinery. While not a heavily industrialized area, the presence of some light manufacturing and transportation corridors (Highway 49 and I-57) adds to the potential for localized air pollution. The urban-rural gradient is pronounced; moving away from the city center quickly leads to open farmland and forested areas. This gradient impacts dispersion patterns, with pollutants potentially concentrating within the city basin during calm weather conditions. The prevailing winds generally flow from the southwest, influencing the transport of pollutants into and out of the area.

Paragould’s air quality follows a distinct seasonal pattern, largely dictated by meteorological conditions and agricultural practices. Spring (March-May) often sees elevated particulate matter due to agricultural tilling and burning, coupled with increased pollen counts. Warm, humid air can lead to stagnant conditions, trapping pollutants near the ground. Summer (June-August) typically experiences better air quality, thanks to stronger winds and convective mixing, which disperse pollutants. However, ozone formation can be a concern during hot, sunny days. Autumn (September-November) brings a return of agricultural burning and cooler temperatures, potentially leading to temperature inversions – where a layer of warm air traps cooler, polluted air below. These inversions are most common in October and November. Winter (December-February) generally has the cleanest air, with reduced agricultural activity and stronger, more consistent winds. However, wood burning for heating can contribute to localized particulate matter spikes, particularly during calm, cold periods. Sensitive groups, including children, the elderly, and those with respiratory conditions, should limit strenuous outdoor activity during spring burning seasons and periods of temperature inversion. Monitoring local conditions and heeding any health advisories is crucial for protecting respiratory health throughout the year.
