Key_:
bit on means:
bit 0: inland water flag
bit 1: low visible screen failed, reversed snow detection
bit 2: low NDSI screen failed, reversed snow detection
bit 3: combined temperature and height screen failed, snow reversed because too warm and too low
This screen is also used to flag a high elevation too warm snow detection,
in this case the snow detection is not changed but this bit is set.
bit 4: too high swir screen and applied at two thresholds:
QA bit flag set if band6 TOA > 25% & band6 TOA <= 45%,
indicative of unusual snow conditon, or snow commission error;
snow detection reversed if band6 TOA > 45%
bit 5: MOD35_L2 probably cloudy
bit 6: MOD35_L2 probably clear
bit 7: solar zenith screen, indicates increased uncertainty in results
