摘要: Pseudo-invariant ground targets have been extensively used to monitor the long-term radiometric calibration stability of remote sensing instruments. The NASA MODIS Characterization Support Team (MCST), in collaboration with members from U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center, has previously demonstrated use pseudo-invariant ground sites for monitoring Terra Landsat 7 ETM+ sensors. This paper focuses on results derived observations made over Sonoran Desert. Additionally, 5 TM data Desert site were evaluate temporal this site. Top-ofatmosphere (TOA) reflectances computed closely matched TM, ETM+, spectral bands selected regions interest. impacts due different viewing geometries, or effect of test Bi-directional Reflectance Distribution Function (BRDF), are also presented.
