Goniometric observations of light scattered from soils and leavesThe laboratory established at NASA-Goddard to measure and model the light-scattering properties of soil samples and individual plant leaves employs two goniometers: one for the measurement of directional reflectance and transmittance from vertically-mounted leaf samples, and the other for measurement of directional reflectance from such horizontal, semiinfinite particulate surfaces as soil samples. Sample observations of various soil minerals and plant leaves are presented; these goniometric data are compared to the results of a reflectance model from particulate surfaces and those of a ray-tracing model of leaf reflectance and transmittance.
