Manufacturing and technology industries produce large amounts of air pollutants. Ulsan Metropolitan City, South Korea, is well-known for its large industrial complexes; in particular, the concentration of SO<sub>2</sub> here is the highest in the country. We assessed SO<sub>2</sub> monitoring sites based on conditional and joint entropy, because this is a common method for determining an optimal air monitoring network. Monthly SO<sub>2</sub> concentrations from 12 air monitoring sites were collected, and the distribution of spatial locations was determined by kriging. Mean absolute error, Root Mean Squared Error (RMSE), bias and correlation coefficients were employed to evaluate the considered algorithms. An optimal air monitoring network for Ulsan was suggested based on the improvement of RMSE.
