Abstract

The relationship between normalized corn yields and monthly rainfall was examined at the county level. The gridded NCEP (National Centers for Environmental Prediction) multi-sensor rainfall data, and the quality control and real-time NWS (National Weather Service ) cooperative data were employed for computing the monthly rainfall estimates. The correlation between normalized corn yield and rain suggests that the real-time multi-sensor data is of comparable quality to the quality control gage data for purposes of predicting county crop yields. The rainfall is generally between 125mm and 50mm for large yields and less than 100mm for low yields.
