Temporal classification of ozone and nitrogen (IV) oxide as pollution indicator of air on Split area

In this paper a set of quantitative descriptive and hourly analytical data of quality indicators (NO2 and O3) of air on Split area were analyzed by multivariate statistical technique. Multivariate statistical technique such as cluster analysis (CA), factor analysis (FA) and principal component analysis (PCA) were employed to investigate temporal classification of ozone and nitrogen(IV) oxide during the year 2015. The concentrations of these indicators of air quality are interdependent and influenced by different chemical processes, complex mechanisms of emission-production and consumption. The implementations of these analyses are very important to define the contribution of different sources of pollution in certain area. The obtained results show and explain similarity or dissimilarity of these indicators between period of time, identifications of pollution indicators responsible for temporal variations and hidden factors explaining the structure of database.
