2. Introduction/Motivation
The Moderate Resolution Imaging Spectroradiometer (MODIS) is a 36-spectral-band VIS/NIR/IR sensor
MODIS is a great success to help better understand global change, to assist policy makers in making sound decisions concerning the protection of our environment
Due to sensor problem, 40% of the data of band 6 on Terra/MODIS is bad. Other 60% are good.
This band of Aqua/MODIS has been widely used for detection of snow/cloud/aerosol.
Results using various methods are shown in the report. The best results are shown here.

How to use the 60% good data to correct the 40% bad data?

4. Scattering between band 6 and band 7
R= for 1,100,802 samples
band 6 ( x-coordinate)
band 7 ( y-coordinate)
Band 6 = *band7
