Abstract: Environmental problems are receiving increasing attention in socio-economic and health studies, fostering advances in recording and data collection of related real-life processes. However, traditional tools for data processing are often found too restrictive as they do not account for the rich nature of such data sets. In this paper, we propose a simple statistical perspective on forecasting environmental data collected sequentially over time across some predefined geographic region. We treat such data set as a surface (or functional) time series with a possibly complicated geographical domain. Using techniques from functional data analysis, we develop a forecasting methodology that allows to account for both geographic and temporal dependencies. This methodology allows integration of traditional multivariate techniques to provide forecasts surfaces. We demonstrate the practical value of our approach with a forecasting example of ground-level ozone concentration across Germany, showcasing its effectiveness and potential for broad application.
