SATURN-07 CDOM calibration evaluation
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 |
