外文摘要：Since May 31， 2003， when the scan line corrector (SLC) on the Landsat-7 ETM+ failed， the primary foci of Landsat-7 ETM+ analyses have been on understanding and attempting to fix the problem and later on developing composited products to mitigate the problem。 In the meantime， the Image Assessment System personnel and vicarious calibration teams have continued to monitor the radiometric performance of the ETM+ reflective bands。 The SLC failure produced no measurable change in the radiometric calibration of the ETM+ bands。 No trends in the calibration are definitively present over the mission lifetime， and， if present， are less than 0。5% per year。 Detector 12 in Band 7 dropped about 0。5% in response relative to the rest of the detectors in the band in May 2004 and recovered back to within 0。1% of its initial relative gain in October 2004。
