AcronymsTable 8.3.1.3.3.2-1 gives the format for the LAC/HRPT Level 1b data record for NOAA-N (Version 3, post-April 28, 2005, all spacecraft). Eight and 16-bit extracts of the LAC/HRPT Level 1b data will be supported by CLASS for NOAA-N, but are still to be determined at the time of this writing.

| QUALITY INDICATORS | ||||||||
| Quality Indicator Bit Field (if a bit is on (=1), the statement is true) bit 31: do not use scan for product generation bit 30: time sequence error detected within this scan (see below) bit 29: data gap precedes this scan bit 28: insufficient data for calibration (see below) bit 27: earth location data not available (see below) bit 26: first good time following a clock update (nominally 0) bit 25: instrument status changed with this scan bit 24: sync lock dropped during this frame bit 23: frame sync word has errors bit 22: frame sync returned to lock bit 21: frame sync word not valid bit 20: bit slippage occurred during this frame bits 19-9: <zero fill> bit 8: TIP parity error detected bits 7-6: reflected sunlight detected ch 3B (0=no anomaly; 1=anomaly; 3=unsure) bits 5-4: reflected sunlight detected ch 4 (0=no anomaly; 1=anomaly; 3=unsure) bits 3-2: reflected sunlight detected ch 5 (0=no anomaly; 1=anomaly; 3=unsure) bit 1: resync occurred on this frame bit 0: pseudonoise occurred on this frame |

| Scan Line Quality Flags [Time Problem Code] (If a bit is on (=1),
the statement is true. All bits off implies the scan time is as
expected.) bit 7: time field is bad but can probably be inferred from the previous good time bit 6: time field is bad and can't be inferred from the previous good time bit 5: this record starts a sequence that is inconsistent with previous times (i.e., there is a time discontinuity). This may be associated with a spacecraft clock update. (See bit 26, Quality Indicator Bit Field.) bit 4: start of a sequence that apparently repeats scan times that have been previously accepted bits 3-0: <zero fill> |
30 | 30 | u | 1 | 1 | 0 | ||
| Scan Line Quality Flags [Calibration Problem Code] (If a bit is on (=1), the statement is true. These bits complement the channel indicators; all bits set to 0 indicates normal calibration.) bit 7: scan line not calibrated: all IR channels failed calibration. bit 6: scan line marginally calibrated: one or more IR channels marginally calibrated, or one or more, but not all, IR channels failed calibration. bit 5: scan line not calibrated: bad or insufficient PRT data bit 4: scan line marginally calibrated: marginal PRT data bit 3: some uncalibrated channels for this scan line (i.e., one or more, but not all, IR channels failed calibration). bit 2: No visible calibration due to either the presence of MIRP pseudonoise in place of AVHRR data or calibration processing turned off. bit 1: <zero fill> bit 0: <zero fill> |
31 | 31 | u | 1 | 1 | 0 | ||
| Scan Line Quality Flags [Earth Location Problem Code] (If a bit is
on (=1), the statement is true. All bits set to 0 implies the earth
location was normal.) bit 7: not earth located because of bad time; earth location fields zero-filled bit 6: earth location questionable: questionable time code (see time problem flags above) bit 5: earth location questionable: marginal agreement with reasonableness check bit 4: earth location questionable: fails reasonableness check bits 3-2: <zero fill> bit 1:<zero fill> bit 0: <zero fill> |
