Nandikotkūr, nestled in the state of Andhra Pradesh, India, occupies a relatively flat terrain at approximately 15.87°N latitude and 78.27°E longitude. The city’s geography is characteristic of the Krishna River delta region, a fertile agricultural zone dominated by rice paddies and sugarcane cultivation. This agrarian landscape significantly influences local air quality, with seasonal burning of crop residue contributing to particulate matter. Nandikotkūr is not directly adjacent to a major body of water, though the Krishna River flows within a reasonable distance, impacting local humidity and wind patterns. The surrounding landscape is predominantly rural, transitioning to more densely populated areas as one moves towards larger regional hubs like Vijayawada. While Nandikotkūr itself isn’t a major industrial centre, its proximity to developing industrial corridors along the river basin introduces potential sources of pollution. The urban-rural gradient is fairly sharp, with a noticeable increase in vehicular traffic and construction activity within the city limits. This concentrated activity, combined with the region’s generally low wind speeds, can exacerbate pollutant concentrations, particularly during calmer weather conditions. The relatively low elevation contributes to the potential for temperature inversions, trapping pollutants near the ground.

Nandikotkūr experiences a tropical climate with distinct wet and dry seasons. Air quality generally worsens during the dry season, from November to May, as dust from agricultural lands and construction activities becomes more prevalent. January and February often see stagnant air masses and temperature inversions, trapping pollutants and leading to poorer air quality. The pre-monsoon months of April and May are particularly challenging due to increased temperatures and wind speeds that stir up dust. The arrival of the southwest monsoon in June brings a temporary respite, with rainfall effectively washing away particulate matter and improving air quality. However, increased humidity can also promote the formation of secondary pollutants. Post-monsoon, from September to November, sees a gradual deterioration as agricultural burning increases in preparation for the next planting season. October is often a period of moderate pollution. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor exposure during the dry season and periods of agricultural burning. Monitoring wind direction is crucial; winds from agricultural areas will likely carry higher pollutant loads. Avoiding strenuous activity during peak pollution times is advisable.
