Crop-climate modeling using spatial patterns of yield and climate. Part 1: background and an example from Australia.

Abstract

A new technique in statistical crop-climate analysis, the direct linking of spatial patterns of crop yield and spatial patterns of climate, is explored. Yield and climate data from networks of crop reporting districts and meteorological stationsa are decomposed into orthogonal components using principal components analysis. Each yield component is then expressed as a function of the climate components using multiple regression.-from Authors
