Tansient light fluctuation measurements are reported for soybean, corn, and brome‐alfalfa canopies. The frequencies of the light fluctuations are obtained with variance spectra and band‐pass filter analysis. The variance contributions for frequencies from 0.01 Hz to 30 Hz are given for the three canopies. The distribution of flux density levels was also measured and reported.
