Abstract

Bivariate splines are smooth piecewise polynomial functions over a triangulation of polygonal domain. We use these functions to approximate the ozone concentration based on the measurements at EPA stations over the U.S. and forecast the value, say at Atlanta. I will first explain bivariate splines and then explain our approach for forecasting. Finally numerical results will be demonstrated to show that our bivariate splines can do a pretty good job of prediction. A comparison of a traditional forecasting method will also be given.
