Quality Control Flags
Quality control flags indicate any assumption(s) made on the data. The qualifier is any single or combination of the following values.
| Value |
Corresponding description |
| mid_point_assumed |
Midpoint- if the exact location of the Aircraft Report is not provided, the midpoint between two locations is assumed. |
| no_time_stamp |
No time stamp - if a time stamp is wrong or not provided. |
| flt_lvl_range |
Flight level range - if a range instead of a specific altitude is given for flight level information. |
| above_ground_level_indicated |
Above ground level (AGL)- if the flight level is expressed as AGL as opposed to mean sea level (MSL). Or if the flight level is recorded as "during descent" (DURD), in which case the surface elevation plus 100 ft. is used from the closest identifier. |
| no_flt_lvl |
No flight level - if no flight level information can be deciphered from the raw Aircraft Report. The decoder fills in the flight level with the altitude of the cloud observation. If this information is unavailable, then the altitude of icing is used. If icing information is absent, then the altitude of turbulence is used. |
| bad_location |
Bad location - if the location from the "/OV" group is greater than 500 km from the leading identifier, or if the location identifier is not available. In this situation, the lat and lon from the leading identifier is used. |
