Test site characteristicsTest site selection is the most important choice indetermining the uncertainties in reflectance-basedapproachP Goal is to understand the interaction between the surfaceand the atmosphereP Test site characteristics! High, flat spectral reflectance and nearly lambertian! Large geographic size with spatial uniformity! Low aerosol loading (high elevation)! Accessible and historical understanding of siteP Other choices such as radiative transfer code, aerosolmodel, instrumentation are also important! However, consistency of these will give good precision! Site selection will more dramatically impact theuncertainties and can increase the importance of theabove items
Spectral reflectance of test sitesIdeal surface is flat spectrallyP Removes uncertainty due to lack of knowledge in thesensor spectral responseP Allows for a direct comparison of sensors withoutspectral corrections
