Note: Bits are listed from the MSB (bit 31) to the LSB (bit 0).
Bit(s) Description
28-31 band 15 data quality four bit range;
0000 -- highest quality
0111 -- noisy detector
1000 -- dead detector; data interpolated in L1B
1001 -- solar zenith >= 86 degrees
1010 -- solar zenith >= 85 and < 86 degrees
1011 -- missing input
1100 -- internal constant used in place of climatological data
for at least one atmospheric constant
1101 -- correction out of bounds pixel constrained to extreme
allowable value
1110 -- L1B data faulty
1111 -- not processed due to deep ocean or clouds
