The table below contains the quality flags associated with CDOM sensor calbration evaluations and the associated scaling used to bring various sensors into alignment. Refer to the QA/QC general information page for information on the different quality levels. The following slides provide details on CDOM data scaling & data quality evaluation: SATURN CDOM Sensor Performance & Data Scaling.pptx
SATURN-07
| Quality Flag | Start Time | End Time | Scale Factor | Offset | Comment | Instrument |
|---|---|---|---|---|---|---|
| QL3 | 12/4/12 | 3/22/13 | 0.769 | -2.243 | This CDOM sensor was installed at SATURN-07 for several deployments between late 2012 and mid-2014. Other sensors were deployed between and after these deployments. Sensor checks in reference solutions were used to scale output from the SATURN CDOM sensors to a common scale. The data from this sensor were scaled by a factor of 0.767 and corrected for a small offset. | FLCDSB-1686 |
| QL2 | 4/23/13 | 10/17/13 | 0.876 | 0.216 | Sensor checks in reference solutions were used to scale output from the SATURN CDOM sensors to a common scale. The data from this sensor during this time were scaled by a factor of 0.88 and corrected for a small offset. | WSCD-1337 |
| QL3 | 10/31/13 | 1/30/14 | 0.769 | -2.243 | This CDOM sensor was installed at SATURN-07 for several deployments between late 2012 and mid-2014. Other sensors were deployed between and after these deployments. Sensor checks in reference solutions were used to scale output from the SATURN CDOM sensors to a common scale. The data from this sensor were scaled by a factor of 0.767 and corrected for a small offset. | FLCDSB-1686 |
| QL3 | 1/30/14 | 4/11/14 | 0.814 | -2.824 | This CDOM sensor was installed at SATURN-07 for several deployments between late 2012 and mid-2014. Other sensors were deployed between and after these deployments. Sensor checks in reference solutions were used to scale output from the SATURN CDOM sensors to a common scale. The data from this sensor were scaled by a factor of 0.767 and corrected for a small offset. | FLCDSB-1686 |
| QL2 | 4/29/14 | 10/23/14 | 1.183 | -0.67 | This sensor was deployed for a single deployment at SATURN-07 during 2014. Sensor checks in reference solutions were used to scale output from the SATURN CDOM sensors to a common scale. The data from this sensor during this time were scaled by a factor of 1.18 and corrected for a small offset. | WSCD-1339 |
| QL4 | 1/15/15 | 1/29/16 | 0.72 | -0.758 | Beginning in early 2017 Turner Designs Cyclops CDOM sensors replaced the WETLabs sensor at SATURN-07. The sensors have had multiple issues with performance while deployed. While the standard readings were used to scale sensor output for the the cyclops deployments at SATURN-07, it should be noted that standard readings with these sensors have not yielded consistent results. These data and corrections are questionable and should be used with caution. | CD218-0535 |
