Nitrogen dioxide is found in the atmosphere as a key ingredient in the photochemical formation of smog and acid rain, nitrogen dioxide is a poisonous gas that is formed during combustion. Toxic at high concentrations, it reacts with moisture in the air to form nitric acid, which is highly corrosive and dangerous to plants and animals. In this study, we present a predictive model for nitrogen dioxide concentrations measured between 2017 and 2024 at ground level in a national network of monitoring stations. The model is based on a statistical approach to measurements from 152 automatic measurement points, with an hourly resolution. The analysis carried out allowed the construction of a mathematical model in order to make an effective prediction. The algorithms used were of the Recursive least squares filter type. The application used was made possible by running a dedicated software in PyCharm. It was found that the model for daytime concentrations depends linearly on a series of parameters monitored by the national network.
