| Subject: | TWP/AOD/C2 - Reprocess: airmass field is incorrectly set to -1 when failing QC. |
| DataStreams: | twpmfrsraod1michC2.c1 |
| Description: | The qc_airmass field indicates that values in the airmass field are set to -9999, the missing_value, when qc_airmass = 1 (QC bit 1 has tripped). In reality, the values are set to -1 and will not be filtered out by programs that automatically remove missing values. This will be fixed in a future reprocessing task. |
| Suggestions: | Either filter out any negative airmass values or filter out values that match times when qc_airmass > 0. |
