Data for: Agricultural production in the United States and its synchronism with the cycles of solar activity

The present work focused on estimating the cross-correlation between the time series of agricultural production variables and the variables of the Space Weather Wolf Number (W) in the United States, in both cases the annual averages were processed. The Fast Fourier Transform (FFT) methodology was used.本研究聚焦于估算美国农业生产变量时间序列与空间天气沃尔夫数（Space Weather Wolf Number，W）变量间的互相关性，两类变量均采用年度平均值进行处理。本研究采用快速傅里叶变换（Fast Fourier Transform，FFT）方法开展分析。
