A continuing series of field campaigns to Lunar Lake, Nevada, has been established for the development of ground-truth measurement protocols and assessment of measurement uncertainties for the ground-based calibration of on-orbit satellite sensors. In June 1997, an ensemble of field radiometers was deployed to validate the fundamental reflectance and radiance measurements of the Land Satellite (Landsat-5) Thematic Mapper (TM) and the Satellite Pour l'Observation de la Terre (SPOT-2) Haute Resolution Visible (HRV) satellite instruments. Prior to their deployment to Lunar Lake, many of the field instruments measured a common sphere source at the University of Arizona. The results, presented in this work, showed large variations in the relative stabilities of the field instruments, and demonstrate the need for in-depth characterization of field instruments for an accurate assessment of instrument performance and emasurement uncertainty.
