Thermal Leak (Bands 5, 6 ,7 and 26)


Thermal out-of-band leakage into the SWIR Bands (5, 6,7,and 26) was evaluated by viewing the Earth at night with the MODIS instrument in day mode. Band 28 was selected to determine the leak coefficients. These coefficients were applied to mitigate the effect. The coefficients have been applied to the calculation of m1 after 12/16/2002, LUT version Energy near 5.3 ┬Ám contributes to the SWIR bands (Bands 5, 6, 7 and 26). In June 2003, Band 25 was selected to determine the leak coefficients.

Incomplete Calibration for Band 21


Band 21 calibration is imprecise at high temperatures.

Impact to L1B Data Set

This effect causes increased uncertainty in the brightness temperature due to the indirect nature of the calibration. Detector to detector striping exists, but is within specifications.

Estimated Impact to L2 Science Products

Science research will be seriously impacted until the calibration can be extended.
