Flag=1 (Good): Temperature is within -2 to 35 degrees C and depth is within 0 to 2000m. Flag=3 (Suspect): Values are near the boundaries of expected ranges. Flag=4 (Bad): Values exceed global physical limits (e.g., temperature below -2C or above 35C, negative depth, depth exceeding sensor rating).

A spike is identified when a single point deviates significantly from both its predecessor and successor. Flag=1 (Good): No spike detected, temperature change is gradual and consistent. Flag=3 (Suspect): Small spike detected (1-2 degrees C difference), could be real thermocline crossing or minor sensor noise.

variable qc_rollover   byte  
attribute qc_rollover _FillValue byte 127
attribute qc_rollover actual_range byte 1, 3
attribute qc_rollover comment String Digit Rollover Test: Detects sensor digit rollover errors where values suddenly jump when they exceed the sensor's digital range (e.g., jumping from 99.9 to 0.0 instead of continuing to 100.0). Flag=1 (Good): No rollover pattern detected in the data. Flag=3 (Suspect): Pattern resembles possible rollover but could be real environmental change. Flag=4 (Bad): Clear rollover signature detected - sudden large jump that resets to near-zero or sensor minimum, indicating sensor range exceeded or firmware bug.

attribute qc_temp_stuck actual_range byte 1, 4
attribute qc_temp_stuck comment String Stuck Value (Flat Line) Test: Identifies when the temperature sensor reports identical values for an extended period, which is physically unlikely in a moving ocean environment. Flag=1 (Good): Normal variability in temperature readings. Flag=3 (Suspect): Temperature shows unusually low variability over several readings (variance less than 0.01 degrees C), could indicate sensor in thermally stable layer or beginning of sensor failure. Flag=4 (Bad): Temperature is completely constant (zero variance) over many consecutive readings, indicating sensor malfunction, frozen/stuck sensor, or data transmission repeating same value.

Flag=1 (Good): Normal variability in salinity readings. Flag=3 (Suspect): Salinity shows unusually low variability over several readings, could indicate sensor in stable water mass or beginning of sensor failure. Flag=4 (Bad): Salinity is completely constant (zero variance) over many consecutive readings, indicating sensor malfunction, frozen/stuck sensor, or data transmission repeating same value.

variable qc_RoC   byte  
attribute qc_RoC _FillValue byte 127
attribute qc_RoC actual_range byte 1, 3
attribute qc_RoC comment String Rate of Change (RoC) Test: Evaluates whether the rate of temperature change over time or depth is physically realistic for the ocean environment. Unlike the spike test which looks at isolated points, this test examines sustained trends. Flag=1 (Good): Temperature change rate is within expected oceanographic bounds (typically less than 1 degree C per 10m depth or per minute). Flag=3 (Suspect): Rate of change is elevated but possible in strong thermoclines or frontal zones. Flag=4 (Bad): Rate of change exceeds physical possibility, indicating sensor drift, calibration issues, or data corruption.
