Newark, Ohio, situated at coordinates 40.0706° N, 82.4250° W, occupies a pivotal position within the Till Plains of central Ohio. This landscape, sculpted by glacial activity during the last Ice Age, is characterised by gently rolling hills and relatively flat terrain. The city’s elevation, hovering around 866 feet (264 meters), contributes to localized weather patterns. Newark lies within the watershed of the Licking River, a tributary of the Ohio River, influencing local humidity and potential for localized flooding events which can impact pollutant dispersion. Historically, the area was a mix of agricultural land and small-scale industry, a legacy still visible in surrounding land use. While agriculture remains present, the region has seen increasing suburban sprawl extending from Columbus, approximately 40 miles west. This urban-rural gradient creates complex air quality dynamics. The proximity to major transportation corridors, including Interstate 70 and State Route 161, introduces significant vehicle emissions. Furthermore, Newark’s location downwind of larger industrial centers to the west and north can result in the transport of pollutants, impacting local air quality. The relatively flat terrain can also exacerbate temperature inversions, trapping pollutants near the ground.

Newark, Ohio experiences a distinct four-season climate, profoundly influencing its air quality. Spring (March-May) often sees moderate pollution levels as temperatures rise and vehicle use increases after winter, coupled with agricultural burning. Summer (June-August) typically presents the cleanest air, aided by prevailing winds and rainfall that help disperse pollutants, though ozone formation can be a concern during hot, stagnant periods. August is often the most favourable month for outdoor activity. Autumn (September-November) brings a resurgence of pollution as temperatures drop, leading to increased wood burning for heating and the potential for temperature inversions trapping pollutants. November can be particularly challenging. Winter (December-February) is generally the period of poorest air quality. Cold temperatures encourage increased use of fossil fuels for heating, and frequent temperature inversions, common in the Ohio Valley, trap pollutants close to the ground. January and February are months to limit strenuous outdoor activity. Sensitive groups – children, the elderly, and those with respiratory conditions – should be particularly cautious during winter and autumn. Fog, common in the colder months, can exacerbate particulate matter concentrations. Meteorological conditions, like stagnant high-pressure systems, significantly worsen air quality during these periods.
