Description
The brightness temperature for each resolution unit (DN) is twice as large as anticipated.
Impact to L1B Data Set
N/A
Estimated Impact to L2 Science Products
This data characteristic causes a complication in optimization of the Terra SST product.
Cause of Effect
Bands 31 and 32 have application to both surface temperature and fire detection studies. The MODIS Science Team expected that the Bands 31 and 32 would need dual electronic gains. However, Santa Barbara Research Group was able to meet all specifications with a single gain.
Mitigation Approach/ Added Testing to Characterize Effect
In LUT V2.4.3.1, the L_max values for bands 31 and 32 were increased to correspond to a saturation temperature of about 388K.
Estimated Schedule to Complete
TBD
