| 1 | BMS | | Upwelling LI-190 | 05/13/2022 | 11:44:00 | 05/13/2022 | 12:25:00 | The LICOR Quantum sensor was facing toward the sun during this time so that it could be calibrated. Data should not be used during this time. |
|---|
| 2 | BMS | | Upwelling LI-190 | 05/12/2021 | 10:20:00 | 05/12/2021 | 12:13:00 | The relay multiplexer on the SRRL BMS radiometer tower had a problem (old age/possible moisture) that caused low voltage measurements on the main CR3000 wiring panel to read bogus, this includes all 40-South measurements and all upwelling shortwave measurements (except upwelling CMP11). |

| 3 | BMS | | Upwelling LI-190 | 09/29/2020 | 11:43:00 | 09/29/2020 | 12:18:00 | The LICOR Quantum sensor was facing toward the sun during this time so that it could be calibrated. Data should not be used during this time. |

| 4 | BMS | | Upwelling LI-190 | 09/14/2018 | 11:33:00 | 09/14/2018 | 12:28:00 | The LICOR Quantum sensor was facing toward the sun during this time so that it could be calibrated. Data should not be used during this time. |
|---|
| 5 | BMS | | Upwelling LI-190 | 06/14/2016 | 10:47:00 | 06/14/2016 | 14:50:00 | The LICOR Quantum sensor was facing toward the sun during this time so that it could be calibrated. Data should not be used during this time. |

| 6 | BMS | | Upwelling LI-190 | 04/27/2015 | 00:00:00 | 12/31/2023 | 23:59:00 | This Data Quality Statement (DQS) is in regard to the Albedo Quantum Calculation, be sure to check DQS in regard to both Upwelling LI-190 and Global LI-190 since both are used to calculate Albedo Quantum and the Global LI-190 has had numerous issues. As of 3/29/2024 at 10:18 MST the albedo calculation was updated to use Global PQS1 instead to resolve this issue. Historical data since 1/1/2024 was corrected on 3/31/2024 to use the Global PQS1. |

| 7 | BMS | Q20558 | Upwelling LI-190 | 03/22/2006 | 15:00:00 | 03/28/2006 | 14:32:00 | The LICOR Quantum sensor is reading very low (and negative when irradiance levels are low enough, near sunrise/set). Sensor was replaced with S/N Q20555. |
