      \\n Bit fields within each byte are numbered from the left: 7, 6, 5, 4, 3, 2, 1, 0. The left-most bit (bit 7) is the most significant bit. The right-most bit (bit 0) is the least significant bit. bit field Description Key --------- ----------- --- 0 Cloud Mask Flag 0 = Not determined 1 = Determined 2, 1 Unobstructed FOV Quality Flag 00 = Cloudy 01 = Uncertain 10 = Probably Clear 11 = Confident Clear PROCESSING PATH --------------- 3 Day or Night Path 0 = Night / 1 = Day 4 Sunglint Path 0 = Yes / 1 = No 5 Snow/Ice Background Path 0 = Yes / 1 = No 7, 6 Land or Water Path 00 = Water 01 = Coastal 10 = Desert 11 = Land ____ END BYTE 1 ______________ ___________________________________________ bit field Description Key --------- ----------- --- 1-KM FLAGS ---------------------- 0 Non- cloud obstruction Flag 0 = Yes / 1 = No 1 Thin Cirrus Detected (Solar) 0 = Yes / 1 = No 2 Snow cover from ancillary map 0 = Yes / 1 = No 3 Thin Cirrus Detected (Infrared) 0 = Yes / 1 = No 4 Cloud Adjacency (cloudy, probably 0 = Yes / 1 = No cloudy plus 1-pixel adjacent) 5 Cloud Flag - IR Threshold 0 = Yes / 1 = No 6 High Cloud Flag - CO2 Test 0 = Yes / 1 = No 7 High Cloud Flag - 6.7 micron Test 0 = Yes / 1 = No ____ END BYTE 2 ______________ ___________________________________________ bit field Description Key --------- ----------- --- 0 High Cloud Flag - 1.38 micron Test 0 = Yes / 1 = No 1 High Cloud Flag - 3.9- 12 micron Test 0 = Yes / 1 = No 2 Cloud Flag - IR Temperature 0 = Yes / 1 = No Difference 3 Cloud Flag - 3.9- 11 micron Test 0 = Yes / 1 = No 4 Cloud Flag - Visible Reflectance Test 0 = Yes / 1 = No 5 Cloud Flag - Visible/NIR Reflectance 0 = Yes / 1 = No Ratio Test 6 Cloud Flag - NDVI Clear Sky Restoral 0 = Yes / 1 = No Test 7 Cloud Flag - Night Land and Polar 0 = Yes / 1 = No 7.3-11 micron Test ____ END BYTE 3 ______________ ___________________________________________ bit field Description Key --------- ----------- --- 0 Cloud Flag - Ocean 8.6- 11 micron Test 0 = Yes / 1 = No 1 Cloud Flag - Clear Sky Restoral Test 0 = Yes / 1 = No Spatial Consistency 2 Cloud Flag - Clear Sky Restoral Test 0 = Yes / 1 = No Polar Night, Land, Sun-glint 3 Cloud Flag - Surface Temperature Test 0 = Yes / 1 = No 4 Suspended Dust Flag 0 = Yes / 1 = No 5 Cloud Flag - Night Ocean 8.6- 7.3 micron 0 = Yes / 1 = No Test 6 Cloud Flag - Night Ocean 11 micon 0 = Yes / 1 = No Spatial Variability Test 7 Cloud Flag - Night Ocean Low Emissivity 0 = Yes / 1 = No Low Cloud 3.9-11 micron Test ____ END BYTE 4 ______________ ___________________________________________ bit field Description Key --------- ----------- --- 250-m Cloud Flag - Visible Tests -------------------------------- 0 Element(1,1) 0 = Yes / 1 = No 1 Element(1,2) 0 = Yes / 1 = No 2 Element(1,3) 0 = Yes / 1 = No 3 Element(1,4) 0 = Yes / 1 = No 4 Element(2,1) 0 = Yes / 1 = No 5 Element(2,2) 0 = Yes / 1 = No 6 Element(2,3) 0 = Yes / 1 = No 7 Element(2,4) 0 = Yes / 1 = No ____ END BYTE 5 ______________ ___________________________________________ bit field Description Key ---------- ----------- --- 0 Element(3,1) 0 = Yes / 1 = No 1 Element(3,2) 0 = Yes / 1 = No 2 Element(3,3) 0 = Yes / 1 = No 3 Element(3,4) 0 = Yes / 1 = No 4 Element(4,1) 0 = Yes / 1 = No 5 Element(4,2) 0 = Yes / 1 = No 6 Element(4,3) 0 = Yes / 1 = No 7 Element(4,4) 0 = Yes / 1 = No ____ END BYTE 6 ______________ ___________________________________________
