pollutant concentration

The problem of building restoration is one of the key challenges of today in Ukraine, due to the consequences of military operations, as well as the expected depletion of stores of building materials and the harmful impact on the environment. One of the important sources of building materials, economically attractive and available in the Volyn region, is sand mining, on the basis of an appropriate permit from the Ukrainian Geological Survey.

The article addresses the urgent problem of computer modeling of large-scale environmental monitoring datasets using discrete wavelet transforms. The research object consists of time series of harmful pollutant concentrations in the atmosphere, including nitrogen oxides, benzene, and sulfur dioxide, collected from automated stations in Central and Eastern Europe. The input data are characterized by high stochasticity, noise, missing values, and temporal shifts, which significantly com- plicate the extraction of trends and patterns required for forecasting.
