Modelling Night Air Quality Data Using Spatial Interpolation Techniques; A Case Study of Nnamdi Azikiwe University, Awka Campus.

Abstract

This study investigates the nocturnal air quality of Nnamdi Azikiwe University (Unizik) Awka Campus using spatial interpolation techniques for modeling. With increasing concerns over air pollution's adverse effects on human health, particularly during nighttime hours, understanding and mitigating such impacts is imperative. The research aims to assess the spatial distribution of air pollutants across the campus area during nighttime, focusing on key pollutants such as particulate matter (PM), nitrogen dioxide (NO2), sulfur dioxide (SO2), and ozone (O3). To analyze the air quality data collected from a network of monitoring stations positioned across the Unizik Awka Campus, various spatial interpolation techniques such as inverse distance weighting (IDW), kriging, and ordinary least squares (OLS) regression will be utilized. The study will make use of data obtained from the university's environmental monitoring program, which includes meteorological parameters and pollutant concentrations measured at multiple locations over an extended period. The research project intends to use advanced technology like Geographic Information System (GIS) and statistical techniques to create spatial models that can accurately depict the distribution of air pollutants within the campus area during nighttime. The main objective of this research is to provide valuable insights into the spatial variability of air quality parameters, which will help in identifying the hotspots of pollution and evaluating the potential exposure risks to the campus community. This study's results are expected to enhance our knowledge of air pollution patterns at night within the university campus environment. In addition, the spatial models developed during the research can be useful for environmental management and policy-making. By using these models, targeted interventions can be implemented to improve air quality and protect the health and well-being of students, faculty, and staff members who live or work within the Unizik Awka Campus vicinity.
