Comparison of Change in EPIC Simulated Yields
Based on Spatial Scale of Climate Change

CSIRO grid/crop
NE
Corn 5.7 5.1 -10.9 5.8 2.3
Soybean 2.2 1.8 -17.5 2.1 -3.8
SE
Corn 5.0 4.5 -9.7 4.9 -2.2
NW
Wheat 1.85 1.93 5.4 1.96 4.0
SW
Wheat 2.04 2.20 8.0 2.17 6.2

NE = northeast grid; SE = southeast grid; NW = northwest grid; SW = southwest grid
OBS = yield (T/ha) calculated from observed climate
course = simulated yield (T/ha) calculated from coarse scale CSIRO climate change scenario
fine = simulated yield (T/ha) calculated from high resolution RegCM climate change scenario
% change = percentage change in yield from OBS
