The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite has been working well, except that 14 of the 20 detectors in Aqua MODIS band 6 (1.628-1.652 ) are ineffective. As a result, the periodic, along-scan strips in Aqua MODIS band 6 create problems in some high-level MODIS products. This paper demonstrates that MODIS bands 6 and 7 are highly correlated for each scene type. On this premise, we propose a within-class local fitting algorithm to recover missing reflectances of Aqua MODIS band 6. To test the efficacy of the proposed algorithm, experiments on real and simulated data are performed and the recovered images are evaluated qualitatively and quantitatively. The experimental results demonstrate that the proposed algorithm performs well.
