Statistical analysis of in situ spectroreflectance data from sample plots of the shortgrass prairie indicates that green biomass, chlorophyll concentration, and leaf water content are directly inter-related to that composite property of the plot called the "functioning green biomass." Correlations between the reflectance and these three measures of the functioning vegetation have been calculated at 91 wavelength intervals of 0.005 micrometers between 0.350 and 0.800 micrometers by using computer analysis. These spectrocorrelation results show the spectral regions of the optimum sensitivity for remotely estimating the green biomass, chlorophyll, and leaf water of a prairie surface and substantiate the direct interrelationship between these parameters. Comparisons between spectrocorrelation curves from two sampling periods in the growing season identifying regions of the spectrum between 0.350 and 0.800 micrometers that are relatively unaffected by increasing amounts of standing dead vegetation and continue to show strong consistent correlations to the amount of functioning green biomass. /Author/
