A Land Product Characterization System chart comparing Landsat 7 ETM+ to MODIS

Detailed Description

This Land Product Characterization System tool plot represents Top of Atmosphere (TOA) reflectance mean from one of the desert calibration sites named Algeria 3 for both L7 ETM+ and Terra MODIS. The acquisitions have been considered from launch to the current date for both sensors. This plot shows only green band TOA reflectance mean from both sensors for the chosen Centre National d'Etudes Spatiales (CNES) Region of Interest (ROI). It should be noted that MODIS has near daily temporal resolution compared to L7 ETM+ 16-day temporal resolution; therefore, MODIS has a much larger number of acquisitions than ETM+.
