The effect of variance changes of temperature and precipitation on
simulated corn yield at three locations in the central U. S.
DEIA = Des Moines Iowa; ININ = Indianapolis, Indiana;
GINE = Grand Island, Nebraska; PV = precipitation variance change case;
TV = temperature variance change case;
2* = doubled variance; .5* = halved variance case.
Percentage Change is the percentage change of the changed variance case compared to the baseline (no change) case.
