Introduction of the Professional Interpolation Software for Meteorology Data:ANUSPLINN

Spatial grid metrological data is an essential environmental factor for various geo-model and climate-model,and the interpolation software is a tool to make the data space-dependent.As a specially designed interpolation package for meteorological data,ANUSPLIN has advantages of its solid theory of thin plate spline function,high interpolation accuracy by the incorporation of parametric linear sub-model,in addition to the independent spline variables.Furthermore,it is more suitable for time series of meteorological data by processing one more surface layer one time.So many contents of ANUSPLIN,such as the interpolation theory,main data flows,parameters setting,model selection,statistic analyses and input-output formats are introduced through an example.It is expected that this paper is helpful for the researchers to use the ANUSPLIN more easily.
